3.0 Methods

3.1 Study Area

The study area includes all watercourses (e.g., rivers, streams, sloughs, and ditches) located adjacent to or that intersect Highway 99 and are within 30 m of the Project alignment, as well as other watercourses located within the same study area width within the broader Highway 99 corridor between Bridgeport Road in Richmond and Highway 91 in Delta. At the Fraser River South Arm, as well as Deas and Green sloughs, the study area extends to a width of 500 m on either side of the Project alignment (Appendix A, Figure 1a).

For major water features within the study area, information pertaining to fish presence and fish habitat, including basic water quality data, is relatively well-documented. Field sampling therefore focused on upland channelized watercourses (ditches) where fish presence and fish habitat values were largely unknown. Sampling occurred at representative sites at approximately one-kilometre intervals along ditches that parallel Highway 99, and in ditches that intersect the Highway 99 right-of-way (ROW). Given the relatively uniform nature of the typically low-gradient, channelized ditches, this sampling is representative to characterize fish species presence and to assess fish habitat values.

3.2 Temporal Scope

Fish and fish habitat sampling was undertaken in 2014 to document existing conditions in watercourses within the study area. Because water levels, water quality, and fish presence are expected to show appreciable variation seasonally, fish sampling was conducted in spring (March 31-April 1, April 15-16, and April 21-22) 2014 and autumn (October 15-16, 18-19, and 19-20) 2014 to capture the widest range of conditions. Sampling during these time periods also maximizes the potential to document fish species that might be present on a seasonal basis, given anticipated poor water quality conditions during the summer months due to, for example, high water temperatures coinciding with low dissolved oxygen levels. Habitat assessments were primarily conducted during low flows and low water level conditions in the summer (July 14-16), complemented with additional observations during spring and autumn sampling. Water quality measurements were taken during all spring, summer, and autumn field sampling events to provide further information on fish habitat values.

3.3 Study Methods

3.3.1 Literature Review of Major Water Features

Information on hydrology and hydraulics, biophysical characteristics (i.e., fish habitat values, including riparian zone features), and fish use was compiled for the entire length of major watercourses (i.e., river, streams, and sloughs) within the study area. Fish habitat information, including the state of riparian vegetation and water quality data for major watercourses within the study area was complemented with data collected during the 2014 field studies.

3.3.2 Field Habitat Assessment

Aquatic habitat assessments were conducted for major water features and upland watercourses within the study area. It was determined during a review of existing information, and confirmed during spring sampling, that upland watercourses within the study area are relatively uniform in nature. Detailed on-site habitat assessments were therefore conducted at watercourses that appeared to be of higher value to fish, and at a subset of other ditches considered representative of other watercourses within the study area. This approach is consistent with field methods applied to similar studies undertaken in support of linear infrastructure projects in the Lower Mainland. The remaining ditches were assessed based on photographs taken in the field and imagery available online through online mapping services for Richmond, and Delta (Delta 2012, Richmond 2014).

Habitat assessments (both detailed assessments and those based on field photographs and online imagery) were conducted in accordance with Resources Information Standards Committee (RISC) prescribed and standardized guidelines for collection of fish habitat data. For the detailed on-site assessments, data were recorded using RISC site cards, digital forms created in iForm (spring sampling), and FlowFinity (summer and autumn sampling) software installed on an iPad. Photographs were taken of all assessed watercourses.

Approximately 100 m of each watercourse were surveyed at each detailed habitat assessment site. Existing conditions such as water flow, channel and morphological characteristics, and the presence of barriers to fish passage, were visually assessed and recorded. In addition, mesohabitats (pools, riffles, runs, glides) were described. The following physical attributes were measured at each site to characterize watercourse conditions and fish habitat:

Stream stage (the amount of water passing through the channel)

Channel and wetted width (m)

Extent and type of instream fish cover



6

Type and width (m) of riparian vegetation, and crown closure (per cent)

Dominant and subdominant streambed materials

Channel morphology, pattern, and confinement

Field crews investigated the connectivity of watercourses within the study area, and within approximately 100 m outside the study area boundaries. Habitat assessments were conducted primarily during low flows in the summer, but also complemented with additional observations during spring and autumn sampling.

3.3.3 Field In Situ Water Quality Assessment

Basic in situ water quality information was obtained at the majority of sites where fish sampling or habitat assessment was conducted, to better understand habitat values and habitat suitability for different fish species. Water quality parameters were measured at 25 sites in the spring during lead-up to freshet (June 1 per Government of Canada 2014b); 15 sites in the summer, during low flows; and 35 sites in autumn, during the beginning of the rainy season. Water quality parameters were collected using a YSI multi-parameter meter and included temperature (°C); dissolved oxygen (DO, in mg/L), conductivity (µS/m), and pH. The meter was calibrated according to the manufacturer’s instructions prior to each round of field sampling. Digital photographs were taken at each site to document conditions at the time of assessment.

Water quality results for temperature, DO, and pH were evaluated against B.C. Water

Quality Guidelines for the Protection of Aquatic Life (B.C. WQG; B.C. MOE 2006) (Table 3-1). The results were used to help determine habitat suitability and likelihood of fish presence, including the potential seasonality of use.

2 Dependent on fish life stage. The instantaneous minimum concentration of DO for protection of aquatic life is 9 mg/L for buried embryo/alevin life stages and 5 mg/L for all other life stages. Because upland water features typically do not provide suitable spawning habitat for salmonids, the 5 mg/L criterion was used.

3.3.4 Fish Sampling

Information regarding fish presence, distribution, and relative abundance was obtained by conducting a desktop literature review of historic fish sampling records from watercourses within the study area (DataBC 2014, FISS 2014) and fish sampling using gee-type minnow traps in accordance with Fish Collection Methods and Standards (RIC 1997), and Reconnaissance

(1:20,000) Fish and Fish Habitat Inventory Standards and Procedures (RISC 2001). Fish sampling was undertaken within a subset of sites where the literature review identified a gap in fish distribution data. Sampling locations were limited to smaller ditches and lesser sloughs within the study area. Fish presence in major watercourses within the study area (e.g., Fraser River, Deas Slough, and Green Slough) was described using existing published information (e.g., FISS, technical and government reports).

Minnow traps were set at 26 sites during the spring sampling session and 35 sites in the autumn session. Two to four traps were deployed per site, depending on the size of the watercourse and its connectivity and proximity to adjacent sampling sites. Traps were soaked overnight, for a period of approximately 24 hours (range: 18.5 to 24.6 hours). Fish were identified to the species level using freshwater fish species field keys (e.g., McPhail and Carveth 1999). Fish total length was measured to the nearest mm. When non-salmonid species were captured, minimum and maximum fish total length was recorded.

Minnow trapping was selected over other fish sampling techniques (e.g., backpack electrofishing) given the morphology and water quality in the majority of watercourses in the study area. Characteristically high conductivity and turbidity, along with easily disturbed fine bottom sediments, would have substantially reduced the effectiveness of electrofishing sampling.

3.3.5 Incidental Observations

Incidental captures of non-focal aquatic organisms (e.g., amphibians and invertebrates) were identified, recorded in field notes, and released in accordance with RISC guidelines for capturing and handling of live animals (B.C. MELP 1998, RISC 1998, B.C. MOE 2008).

3.4 Data Analysis

Field data were recorded electronically using electronic equivalent of RISC fish collection and habitat assessment forms created in iForm (spring sampling) and FlowFinity (summer and autumn sampling) software installed on an iPad. Data were wirelessly downloaded into a data management system and imported directly into a Microsoft Access database developed for the freshwater fish study program. Data from hardcopy field forms were entered manually into that database.



8

Geomatics data management was supported by the use of ESRI’s geographic information system (GIS) mapping software, specifically ArcSDE SQL server database and ArcGIS server web mapping software. The database information was cross-referenced with photographs and geographic coordinates. Inconsistencies were identified and reviewed to determine the cause of the discrepancy and, if necessary, discrepancies were reconciled

All determination of fish habitat quality and likelihood of fish species occurrence was qualitative (did not involve statistical calculations or modelling). Watercourses were classified based on commercial, recreational, and Aboriginal (CRA) fisheries values, as described in Table 3-2. Where the existing classification for a watercourse was insufficiently assigned or missing, watercourses were coded in accordance with the classification system described in Table 3-2 with consideration of fish access, historic and recent fish sampling data, physical habitat characteristics, and water quality.

Table 3-2 Fish and Fish Habitat Study Watercourse Classification System

CRA Fish Habitat Value Coding Description

Potential for CRA fish presence

Red

Year-round habitat for CRA or listed fish species (e.g., salmonids, eulachon (Thaleichthys pacificus), white sturgeon (Acipenser transmontanus), or green sturgeon (A. medirostris))

Dashed-red Seasonal habitat for CRA or listed fish species (e.g., overwintering habitat for juvenile salmonids)

No CRA fish presence

Orange Significant upstream source of food or nutrients to red or dashed-red habitat

Yellow Non-CRA fish bearing, but with no value to CRA or listed fish species (e.g., resident fish only)

Green No value for fish (CRA, listed, or other fish species) Notes: Watercourse classification was built upon existing municipal mapping (Delta 2003a, 2012, Richmond 2014),

along with previous classification conducted for the Ministry during baseline studies for the South Fraser Perimeter Road Project (Coast River 2006). Existing classifications from municipal mapping provide a varying amount of detail, ranging from a binary description of potential salmonid presence (Richmond 2014) to classification schemes similar to that described in Table 3-2 (Delta 2003a, Coast River 2006).

4.0 Results

This section presents the main findings of the literature review and field studies, and briefly describes data gaps, potential biases, and incidental observations.

4.1 Information Review of Previous Fish Sampling

The FISS (2014) documents fish presence in major catchments and some ditches within the study area (Appendix B, Table 1). Additionally, the Corporation of Delta (2002, 2003a) has assessed fish presence in the major Delta catchment areas FA-5, FA-4, BBA-2, BBA-3, and BBA-1 that overlap with the study area (Appendix A, Figure 2). Past sampling efforts in the vicinity of the Project have resulted in the capture of native and introduced resident fish species. A complete list of these species is provided in Appendix B, Table 2.

4.2 Study Results

The results of the literature review and field studies are presented below. Habitat assessment, water quality, and fish sampling results within upland ditches are also summarized. Data from all detailed habitat assessments are provided in Appendix B, Table 3. Representative photographs of all watercourses are presented in Appendix C, Photos 1 through 112. Water quality data are presented in Appendix B, Tables 4, 5, and 6. Fish capture data are provided in Appendix B, Tables 7 and 8.

4.2.1 Fraser River South Arm

In addition to the Fraser River South Arm, the study area includes several upland watercourses (Appendix A), the existing conditions of which are described below.

Hydrology and Hydraulics 4.2.1.1

The Fraser River is the largest river on the west coast of Canada, draining approximately 250,000 km2 of mountainous terrain in southern B.C. (Kostaschuk and Luternauer 2004). Downstream of Hope, the Fraser River divides into a gravel reach and a sand reach, as determined by the dominant bed-load type (Rosenau and Angelo 2007). The gravel reach extends from Hope downstream to the Fraser River’s confluence with the Sumas River near Mission. The sand reach spans downstream of the gravel reach, from the Sumas River confluence to the river mouth at Sand Heads (Rosenau and Angelo 2007).



10

At the New Westminster trifurcation off the eastern tip of Lulu Island, the lower Fraser River splits into three branches: the South Arm, which extends approximately 35 km to Sand Heads; Annacis Channel, which rejoins the South Arm a short distance downstream; and the North Arm, which further divides into the Middle Arm at the eastern tip of Sea Island near its mouth (Appendix A, Figure 1a).

The South Arm is an estuarine ecosystem influenced by the presence of a tidally driven salt water wedge that flows near the river bottom underneath a freshwater surface layer (Kostaschuk 2002). Mean annual river discharge at Port Mann Bridge (approximately 25 km upstream of the study area) is about 3,600 m3/s (Gray and Tuominen 1999). River flows fluctuate on an annual basis. Heaviest flows occur between May and July during freshet, with normal maximum flows exceeding 8,000 m3/s in June (NHC 2009). From December through March, flows are lower at approximately 1,450 m3/s (NHC 2009). Although dependent on discharge, tide level, bathymetry, and local control from training structures, the South Arm discharges on average approximately 85 per cent of the total river flow (Schaefer 2004).

From the Sumas River confluence downstream to the Fraser River mouth, the riverbed displays a series of deep pools, typically in the river bends and at locations where the river channel narrows. The water surface drops fairly uniformly with no apparent gradient to the riverbed (NHC and Triton 2006). Even during extreme flood conditions, the river gradient is approximately 5 cm/km, indicating that the water level is affected strongly by downstream control, rather than local hydraulic conditions (NHC and Triton 2006). Downstream of New Westminster, the South Arm has deepened appreciably in response to dredging, river training, and confinement by bridges and dikes. On average, bed levels in the South Arm have lowered by 0.1 m/year since the 1970s (NHC and Triton 2006).

The Fraser River transports an average of 17.3 million tonnes of sediment annually (measured at Mission, 84 km upstream of the river mouth), consisting of 35 per cent sand, 50 per cent silt and 15 per cent clay (McLean et al. 1999). Most of the sediment is transported during freshet through the South Arm (McLaren and Tuominen 1999). Heavier sand particles settle on the riverbed during transport; however, finer silt and clay are carried in suspension and deposited in the estuary. About 30 per cent of the sediment is delivered to Sand Heads at the mouth of the Fraser River (Williams et al. 2009). The riverbed in the South Arm is composed almost entirely of sand with a mean particle size of 0.25 mm to 0.35 mm, with little seasonal variation (Kostaschuk et al. 1989). During freshet, sand dunes form on the river bottom from sediment transported by the river. As the flow increases, the dunes expand in height and length, and migrate along the river bottom producing scour or fill as they move (NHC 2009).



11

The river channel width at the Tunnel crossing is approximately 570 m, measured from top of bank to top of bank. Bed levels in the vicinity of the Tunnel crossing have formed as a result of natural scour and deposition, as well as maintenance dredging occurring annually in the river mainstem. The greatest bed level changes seem to have occurred from 1988 through 1989 and 2000 to 2001. Upstream of the Tunnel, the main channel at the dam on Deas Slough experienced about two to four metres of local deposition, while at Deas Island, the river bed lowered by about three to four metres due to scouring. Downstream of the Tunnel crossing, the thalweg impinges on the left bank to the upstream third of Kirkland Island and there is evidence of bank scour. Between the Tunnel and the Lulu Island Delta Main, there is a hole at the left bank that was scoured by four metres between 1988 and 2000, and by lesser amounts in subsequent years. Corresponding deposition occurred immediately downstream of the scour hole. Local deposition also occurred in Ladner Harbour between 2001 and 2009.

Physical Fish Habitat 4.2.1.2

The shoreline of the Fraser River South Arm is characterized by a variety of shore-based industries (e.g., lumber mill; grain, forest products, and rolled paper distribution) and shipping terminals (e.g., Fraser Wharves, Annacis Auto Terminals, Fraser Surrey Docks) (FREMP 2006). The New Westminster trifurcation training structure, which serves to decrease sedimentation, thus reducing dredging requirements, is within this river segment, approximately 15 km upstream of the Tunnel (FREMP 2006).

Despite channeling to minimize sedimentation, annual maintenance dredging (hopper and cutter suction) occurs at several locations within this segment (FREMP 2006, PMV 2014a). Within St. Mungo’s Bend and Annieville Channel, upstream of the study area, regular dredging occurs to allow access by large vessel traffic (FREMP 2006). Infrequent and localized clamshell dredging also takes place to maintain boat and barge access, access to small craft harbours, and moorage (FREMP 2006).

Productive shoreline habitat in the Fraser River South Arm downstream of the trifurcation is generally confined to a narrow band of intertidal marshes, mud- and sandflats around Tilbury Island, along the north and south banks of Annacis Channel, and along the Fraser River banks on the southwest side of Annacis Island (BIEAP - FREMP 2014). Given the extensive industrial activity along the shoreline of the South Arm, a high proportion of habitat is classified as of low (green-coded) or moderate (yellow-coded) productivity (BIEAP - FREMP 2014).



12

Shoreline habitats along the South Arm and their respective FREMP (2014) designations within the study area include the following (also see Appendix A, Figure 3):

1. Low productivity (green-coded) riprap armouring is located on the north bank of the South Arm, upstream of the Tunnel crossing. A short section (approximately 55 m) of shoreline on the north bank just upstream of the Tunnel crossing was designated as high productivity (red-coded) habitat, following works to compensate for disturbance associated with riverbank erosion protection undertaken in 1987. Compensation works included the creation of an intertidal bench that was incorporated into a riprap slope. A narrow strip of upland deciduous woodland, dominated by black cottonwood (Populus

trichocarpa), backs the armoured shoreline by the Tunnel crossing.

2. Riprap armouring offering habitat of moderate productivity (yellow-coded) is located on the north bank of the South Arm, downstream of the Tunnel crossing. A narrow strip of upland vegetated areas, consisting of grass and deciduous woodland dominated by black cottonwood, backs the armoured shoreline downstream of the Tunnel crossing. Compensation works have been undertaken also within this section of shoreline. Riparian habitat, intertidal marsh, and subtidal riverbed habitat were created in 2005 to compensate for disturbance of riparian and in-river habitat associated with the Deas Refit Complex Expansion Project.

3. Shrub and deciduous tree woodland, predominantly black cottonwood, fronted by moderate productivity (yellow-coded) sandflat habitat is located on the south bank of the South Arm (north bank of Deas Island), upstream and downstream of the Tunnel crossing. A small, narrow marsh also occurs downstream of the Tunnel crossing, within moderate productivity (yellow-coded) habitat on the south bank. Riprap armours intermittent sections of the shoreline.

Aquatic Resources 4.2.1.3

The food web of the lower Fraser River ecosystem is detritus-based, with much of the production derived by bacteria living on detrital organic material (Levings 2004). Sources of carbon in the food web include material from shoreline and riparian vegetation, as well as from benthic algae growing on the substrate (Kistritz et al. 1983, Levings 2004). Detritus is used by invertebrates such as chironomids, harpacticoid copepods, and amphipods for secondary production in the estuary, which are in turn consumed by fish (Levings 2004).

The lower Fraser River supports 42 species of fish, six of which are introduced from outside the Fraser River basin (Richardson et al. 2000). Of the native fish species, seven are anadromous and 10 are considered transient within the estuary and lower reaches of the river (Healey 1997). Anadromous species of high CRA importance that rely on aquatic habitats throughout the Fraser River estuary during different stages of their life cycle, include five species of Pacific salmon, i.e., chinook (Oncorhynchus tshawytscha), chum (O. keta), coho (O. kisutch), pink (O. gorbuscha), and sockeye (O. nerka), as well as coastal cutthroat trout (O. clarkii), and steelhead/rainbow trout (O. mykiss).



13

Other fish species that inhabit the lower Fraser River mainstem and its tidal sloughs, backwaters and tributaries include prickly sculpin (Cottus asper), peamouth (Mylocheilus

caurinus), redside shiner (Richardsonius balteatus), northern pikeminnow (Ptychocheilus

oregonensis), starry flounder (Platichthys stellatus), lamprey (Lampetra sp.), and threespine stickleback (Gasterosteus aculeatus) (Richardson et al. 2000).

Introductions of non-native fish species have occurred in the lower Fraser River; however, no major shifts in the species composition, density, and biomass of the native fish community have been recorded (Richardson et al. 2000). Three non-native species that are well-documented to reside in the Lower Fraser River are carp (Cyprinus carpio), brown catfish (Ameiurus nebulosus), and black crappie (Poxomis nigromaculatus).

Life histories, biology and habitat requirements for Pacific salmon, sturgeon, eulachon, trout, and char species of the lower Fraser River are summarized below.

Chinook salmon

Chinook salmon is the largest in size of the Pacific salmon species that return to the Fraser River and its tributaries to spawn (DFO 2011). Spawning locations in the Fraser River watershed are widely distributed over 900 km from the mouth of the Fraser River (DFO 2011). More than 100 spawning sites have been identified in numerous tributaries of the Fraser River (Candy et al. 2002, DFO 2011).

Chinook salmon return to the Fraser River to spawn over an extended period from February to November, as three-, four-, or five-year-old fish (DFO 2011). Generally, stream-type chinook migrate upriver between March and September, while ocean-type chinook migrate between September and November, only a few weeks or even days before spawning (Fraser et al. 1982, Candy et al. 2002, Parken et al. 2008). Spawning occurs from August to December, depending on the stock (Candy et al. 2002).

In their natal streams, chinook spawn from August to December, depending on the stock (Candy et al. 2002). Adult chinook, like other Pacific salmon species, deposit their eggs in gravel and die after spawning. Chinook fry emerge in March through June (Fraser et al. 1982). After emergence from gravel in locations well upstream of the lower Fraser River’s sand reach, stream-type juvenile chinook rear in freshwater for one or more years (Healey 1983, 1991) and migrate to sea as smolts between January and July (Healey 1991, Boehlert 1997). Ocean-type chinook migrate to sea during their first year of life between April and October, after spending only two to five months in fresh water (Healey 1983, 1991). On average, estuarine residence time of juvenile chinook likely ranges between one week to one month (Quinn 2005, Northcote



14

et al. 2007). Stream-type chinook generally do not occupy tidal channels; however, ocean-type chinook are found rearing in the tidal marshes of the Woodward Island complex and Ladner Marsh of the inner Fraser River estuary (Levy and Northcote 1982, Northcote et al. 2007). Their abundance peaks in May and June (Northcote et al. 2007). As they grow, chinook juveniles enter the ocean and begin their offshore migration. The diet of younger juvenile chinook in the inner estuary consists of epibenthic prey (harpacticoid and cyclopoid copepods) associated with the detrital food web (Northcote et al. 2007). Contribution of terrestrial insects and fish to the diet of juvenile chinook increases as they grow (Northcote et al. 2007).

Fraser River chinook are subject to numerous fisheries (DFO 2011). Lower Fraser River ocean-type chinook are commonly caught off the west coast of Vancouver Island, while the South Thompson ocean-type chinook are commonly caught in Alaska, northern, and central B.C. (Tucker et al. 2011). Fraser River chinook salmon stocks are not federally or provincially listed; however, they have experienced depressed production in recent years (DFO 2011). The lower Fraser River chinook stock is numerically dominated by autumn-returning, ocean-type fish originating from the Harrison River (DFO 2011). Over the last decade, Fraser River stream-type chinook escapements declined steeply between 2003 and 2009, with smolts that entered the ocean in 2005 and 2007 having fared particularly poorly (Pacific Salmon Commission 2013). Recent escapements indicate that the declining trend in stream-type chinook may have halted. The rebuilding process has been particularly slow, however, with fish exhibiting early maturation, smaller body size, and lower fecundity (Pacific Salmon Commission 2013). In contrast, escapements for ocean-type chinook have been increasing or showing no discernible trends (Pacific Salmon Commission 2013).

Limiting factors for chinook populations include fisheries-induced and natural (e.g., due to predation) mortality, climatic variability, habitat degradation, or combination. Fraser River chinook are subject to numerous coastal and offshore fisheries. Coastal catches are dominated by ocean-type fish, and fishing mortality exerts some pressure to ocean-type stocks (DFO 2011). Coastal fisheries to some extent, as well as offshore fisheries likely limit the recovery of stream-type chinook (Tucker et al. 2011). Other limiting factors include variability in climatic and oceanographic conditions. Shifts in ocean conditions influence prey availability and abundance, which in turn affect chinook growth rates, year class strength, and survival (Beamish and Mahnken 2001, Trudel et al. 2007, MacFarlane 2010, Duffy and Beauchamp 2011, Tucker et al. 2012). For example, good feeding conditions for rearing chinook that enter the marine environment may result in early rapid growth, which is thought to increase likelihood of survival (Pearcy 1992, Trudel et al. 2007). Natural mortality due to predation may also limit chinook recovery. For example, chinook salmon account for more than 80 per cent of the diet of



15

southern resident killer whales (Orcinus orca) from May to September, when southern resident killer whales are in their summer critical habitat (Hilborn et al. 2012a). Habitat degradation as a result of urbanization, resource extraction activities, and agricultural land use has also contributed to chinook population declines (DFO 1999).

Chum salmon

Chum salmon have the widest geographic distribution of all Pacific salmon, ranging in North America from Monterey, California to the Arctic coast (Salo 1991). Historically in the North Pacific Ocean, they may have constituted up to 50 per cent of the annual biomass of all Pacific salmon combined (Salo 1991). Chum salmon spawn in streams of various sizes, including the lower Fraser River mainstem between Chilliwack and Hope (Ryall et al. 1999).

Chum salmon are the last of the Pacific salmon to return to their natal streams. Returning chum salmon can be divided into early (summer) and late (fall) run stocks (Salo 1991). In the Fraser River, chum are fall run stocks that migrate upstream to spawn from September to December, with peak spawning migration occurring in October (Grant and Pestal 2009). The runs consist of three-, four-, and five-year-old chum, with four-year-olds dominating (Beacham and Starr 1982, Pauley et al. 1988, Salo 1991).

The majority of spawning locations for chum in the Fraser River watershed are located in tributaries of the lower Fraser River downstream of Hell’s Gate, near Hope, as chum are reputed to be poor or unwilling leapers (Salo 1991). Chum rarely ascend fish ladders or other significant obstacles, and only few spawning locations occur in tributaries in the Fraser River canyon (Ryall et al. 1999, Holtby and Ciruna 2008). Most (>90 per cent) of the Fraser River chum production comes from about 10 tributary streams in the lower Fraser River that have natural spawning populations and, in some cases, major hatchery production facilities (Ryall et al. 1999, Holtby and Ciruna 2008). These include the Harrison, Chehalis, Chilliwack, and Stave rivers (Ryall et al. 1999, Holtby and Ciruna 2008).

Once chum salmon arrive at the mouth of their natal stream, they may spend several days milling before ascending. In Skagit Bay, located in Puget Sound, Washington, chum salmon have been reported to mill for about three weeks (Eames et al. 1981). The milling period becomes shorter as the spawning season progresses. Returning adult chum salmon stop feeding just before entering fresh water (Pauley et al. 1988).



16

After emergence, chum fry promptly migrate downstream to the estuary where they linger until they transition to higher salinity waters (Salo 1991). Outmigration occurs from February to June, and peaks between mid-March and the end of April (Beacham and Starr 1982, Salo 1991).

In the estuary and lower reaches of the Fraser River, chum fry prey mainly on harpacticoid copepods (Mason 1974, D’Amours 1987, Webb 1991, Levings et al. 1995). Other prey include gammarid amphipods, chironomid larvae and pupae, and adult insects (Mason 1974, Dunford 1975, Levings et al. 1995). In the estuary, residence time for chum fry has been recorded to range from 11 days to a few weeks (Healey 1982, Levy and Northcote 1982). Movement into the deeper waters of the Strait of Georgia occurs in June, and movement out of the Strait of Georgia occurs soon after, in July (Healey 1980). Migration of chum fry to salt water is obligatory within the first summer after hatching, as chum salmon juveniles lose their ability to tolerate brackish salinities (Pauley et al. 1988). At sea, immature chum salmon become widely distributed throughout the north Pacific Ocean (Pauley et al. 1988).

Chum salmon are harvested in CRA fisheries throughout B.C. (DFO 2012). Catches of inshore chum stocks have been fluctuating since the early 1950s (Ryall et al. 1999). Since the implementation of fisheries management tools in the 1980s, the Fraser River chum stock has exhibited moderate growth (Ryall et al. 1999, Pacific Salmon Commission 2014), with total escapement estimates consistently above the escapement goal from 1990 to the mid-2000s (Hilborn et al. 2012b). Although escapement levels declined from the mid-2000s, the trend appears to be reversing since 2011 (Pacific Salmon Commission 2014). In 2013, the Marine Stewardship Council certified the Fraser River commercial chum fishery as sustainable and well-managed (Marine Stewardship Council 2013).

Coho Salmon

In North America, coho salmon are distributed from Kotzebue Sound in northwest Alaska, to Monterey Bay in California (Sandercock 1991). In B.C., they can be found in nearly every accessible coastal stream. They also migrate some distance inland in large rivers and spawn in smaller tributaries of the Skeena, Bella Coola, Nass, and Taku rivers, and in the middle tributaries of the Fraser River. Coho is the most widespread of the Pacific salmon in B.C., with no one area being the dominant producer (Sandercock 1991).

Coho have the least variable life history of the Pacific salmon species. Adult coho typically return to spawn in the fall and early winter, and discrete seasonal runs do not generally exist (Holtby and Ciruna 2008). They migrate actively during daylight hours, with diel vertical migration also influenced by water turbidity, degree of sexual maturity, and run size (Sandercock 1991).



17

The eggs incubate during winter in the gravels of suitable spawning streams, with incubation timing generally ranging from six to eight weeks (Sandercock 1991). From mid-March to late June, free-swimming fry emerge and take up residency in the stream for a year or more (Fraser et al. 1982, Sandercock 1991). When they are about to transition physiologically into smolts, they begin moving downstream in aggregations of 10 to 50 fish. Outmigration generally occurs from mid-April to mid-June, with a peak observed in mid-May (Fraser et al. 1982). In the estuary, growth is rapid (Sandercock 1991). Similar to chinook, coho smolts remain in the estuary and lower reaches of the Fraser River for a few weeks while physiologically adapting to higher salinity conditions (Fraser et al. 1982).

Coho salmon are not federally or provincially listed; however, the Interior Fraser populations were designated as Endangered by COSEWIC (COSEWIC 2002). The status of the Interior Fraser Coho Salmon is anticipated to be re-assessed by COSEWIC and an updated status report is expected to be produced in 2015 (Decker and Irvine 2013). Coho are taken in net, as well as hook and line CRA fisheries; however, catches in south coastal B.C. have declined from 1.55 million fish in the mid-1980s, to virtually zero in the late 1990s, and have remained low since then (DFO 2002). This decline was largely attributed to overharvesting, and was followed by implementation of conservation measures, such as limiting the exploitation rate to three per cent or less, time and area fisheries closures, as well as non-retention (DFO 2012).

Pink Salmon

In North America, pink salmon is distributed from the Sacramento River, California, to the Beaufort Sea, east of Point Barrow, northwestern Alaska. In B.C., pink salmon distribution ranges from the Taku River on the north B.C. coast to the Fraser River (Heard 1991). Pink salmon have a fixed two-year life cycle resulting in ‘even-year’ and ‘odd-year’ brood lines that are reproductively isolated. In Puget Sound, the southeastern Vancouver Island, and the Fraser River, ‘even-year’ pink are either absent or quite rare (Holtby and Ciruna 2008).

Pink salmon have the shortest life cycle of all Pacific salmon since they always mature as two-year-old fish (Labelle 2009). In the Fraser River, pink salmon return in odd years (Labelle 2009). Return migration typically peaks from late July to early September (Heard 1991). Spawning occurs mostly in September and October, and is typically concentrated in the Fraser River tributaries below Hope, with significant spawning also occurring in the Thompson River (Labelle 2009). The eggs incubate in the gravel for five to eight months (Heard 1991). From mid-April to mid-May, free-swimming fry emerge at night and migrate quickly downstream using sections of the river mainstem characterized by fast-flowing water (Heard 1991). In the estuary, pink fry migrate quickly through the marshes of the lower Fraser River and rear in nearshore areas of the estuary and adjacent coastal waters of the Strait of Georgia (Godin 1981, Levy and Northcote 1982).



18

Pink salmon are not federally or provincially listed (B.C. CDC 2015). They are the most abundant salmon species in B.C. and the Fraser River is a major contributor to total pink salmon production. Fisheries catches increased from the 1950s to the late 1980s, when they exceeded 20 million fish, but subsequently declined in the 1990s (Labelle 2009). Since 1999, exploitation rates on Fraser River pink salmon have decreased substantially, averaging only eight per cent of the total return (Labelle 2009). Fisheries targeting Fraser River pink salmon are limited due to conservation constraints for stocks of concern of other salmonid species, such as the Cultus Lake sockeye, the Interior Fraser coho, and the Interior Fraser steelhead (Labelle 2009).

Sockeye Salmon

In North America, spawning populations of sockeye salmon have been reported from the Sacramento River, California, to the Chukchi Sea, northwestern Alaska (Burgner 1991). Sockeye salmon are found throughout B.C., especially in large river systems with an abundance of large nursery lakes, such as the Skeena and Fraser River systems (Burgner 1991, Holtby and Ciruna 2008). The Fraser River system contains 50 to 60 sockeye salmon stocks that spawn in tributaries of about 22 nursery lakes (Groot and Cooke 1987).

Sockeye salmon has three distinct life history types (Burgner 1991). Kokanee are not anadromous and spend their entire life in fresh water (Burgner 1991). Lake-type sockeye spawn in streams and rear for a year or more in freshwater nursery lakes. River-type sockeye spawn in streams, but rear in flowing water and may transition into smolts soon after emergence. Sea-type sockeye is a special variety of river-type sockeye that rear in the river for several months after emergence from the gravel and enter the ocean in their first year of life (Wood et al. 2008). Lake- and river-type sockeye are found throughout B.C., although river-type predominate northern glacial rivers, whereas lake-type predominate large river systems, such as the Fraser, Skeena, and Nass (Holtby and Ciruna 2008). In the Fraser River, the largest population of sea-type sockeye occurs in the Harrison River (Beamish et al. 2010).

Sockeye salmon are commercially the most valuable of Pacific salmon in the North Pacific region, comprising about 50 per cent of the Fraser River salmon fishery (Birtwell et al. 1987b). Fraser River sockeye salmon typically return as four-year-old adults and populations have characteristic timings of return, broadly classified into four groups or runs (Gable and Cox-Rogers 1993). The early Stuart run consists of populations that spawn in tributaries to Stuart, Takla, and Trembleur lakes of the upper Fraser River watershed (Gable and Cox-Rogers 1993). The three remaining runs, early summer, summer, and late, are not geographically discrete, and each contains populations from throughout the Fraser River drainage (Gable and Cox-Rogers 1993).



19

The peak arrival for early Stuart sockeye typically occurs in early July, followed by the early summer run in late July, the summer run in early August, and the late run about the third week of August (Gable and Cox-Rogers 1993). Late-run stocks may hold in the Fraser River estuary for several weeks before migrating upriver. Consequently, their spawning migration may peak in late September (Gable and Cox-Rogers 1993). At spawning grounds, eggs incubate during winter, and in spring free-swimming fry emerge that take up residency in a downstream nursery lake (Burgner 1991). After rearing for a year, sockeye smolts (age 1+) migrate downstream in fast flowing, mid-channel areas of the river and leave the estuary rapidly (Birtwell et al. 1987b). Smolt outmigration from nursery lakes generally occurs from mid-April to late-May (DFO 2014a). One notable exception is the Harrison sockeye that have a unique age structure and life history compared to all other stocks. Harrison sockeye fry migrate to the estuary shortly after gravel emergence and rear in sloughs of the inner Fraser River estuary, including Deas Slough, before entering the Strait of Georgia (Dunford 1975, Levy and Northcote 1981, 1982, Birtwell et al. 1987b). In Deas Slough, sockeye underyearlings have been caught from April to October, with peak abundance from late June to early July (Birtwell et al. 1987b). Upon entering the Strait of Georgia, sockeye smolts migrate primarily through the Johnstone and Queen Charlotte straits towards the North Pacific Ocean (Groot and Cooke 1987).

Sockeye salmon spawn in a variety of habitats, including headwater streams, small tributaries, river outlets, and lake beaches. Spawning occurs from early August to late November, with average spawning dates exhibiting considerable variability within regions (Linley 1993). Free-swimming fry emerge in spring and rear in freshwater habitats (Burgner 1991). After about a year or more, sockeye smolts (age 1+) migrate downstream in fast flowing, mid-channel areas of the river, and leave the estuary rapidly (Birtwell et al. 1987b). Smolt out-migration generally occurs from early April to the end of May (Beamish et al. 2010). One notable exception is the Harrison sockeye that have a unique age structure and life history compared to all other stocks. Sea-type Harrison sockeye fry migrate to the estuary shortly after gravel emergence and rear in Fraser River estuary habitats, including Deas Slough and Ladner Reach, before entering the Strait of Georgia (Dunford 1975, Levy and Northcote 1981, 1982, Birtwell et al. 1987b). In Deas Slough, sockeye underyearlings have been caught from April to October, with peak abundance from late June to early July (Birtwell et al. 1987b).

Residence time in the Strait of Georgia ranges from 45 to 59 days, with a mean of 54 days (Preikshot et al. 2012). Upon entering the Strait of Georgia, sockeye smolts disperse either as a result of innate behaviour, physical forcing in the marine environment, or both. Relatively large abundances of juvenile sockeye salmon migrate into the waters of the Gulf Islands (Preikshot et al. 2012). During rearing in the marine environment, juvenile sockeye diet is dominated by



20

amphipods, followed by tunicates and calanoid copepods (Beamish et al. 2010, Preikshot et al. 2010). Typically, sockeye juveniles migrate to the North Pacific Ocean in June or July through the Johnstone Strait (Preikshot et al. 2012). However, some Harrison sockeye may migrate later in the calendar year from October to December through the Juan de Fuca Strait (Beamish et al. 2010).

Sockeye salmon are not federally or provincially listed; however, the Cultus Lake population was designated as Endangered by COSEWIC in 2003 (COSEWIC 2003a). On average, sockeye is the most important of the Pacific salmon species in terms of commercial landed value, followed by chinook and chum (DFO 2012). Sockeye salmon is also caught in sport fisheries and in Aboriginal active food driftnet (i.e., gillnet) fisheries on the Lower Fraser River.

Most Fraser River sockeye stocks are recovering from collapse in the early 1900s as a result of river blockages and overfishing (Cass et al. 2000). Since the mid-1980s, efforts undertaken for rebuilding of the stocks have included setting of escapement targets, which were informed by results from historical catch reviews, stock-recruitment analyses, and spawning and lake rearing habitat capacity estimates. To increase escapement, average exploitation rates were also reduced (Cass et al. 2000). Sockeye spawning escapement to the Fraser River gradually increased from an average of 1.5 million fish per year in the 1950s to 10.7 million fish per year in the 1990s (Cass et al. 2000). Increases in escapement have mainly occurred in the large actively managed stocks and cycle lines (e.g., Early Stuart, Late Stuart, Quesnel and Late Shuswap), whereas escapements to less actively managed stocks (e.g., Cultus) have been highly variable since the 1950s (Cass et al. 2000). Recently, escapement variability has been particularly large, with the 2009 return (1.6 million) and 2010 return (28.3 million) among the lowest and highest, respectively, on record since 1952 (DFO 2014b).

White Sturgeon

White sturgeon are known to occur in the mainstems of large river systems of the Pacific coast of North America, such as the Fraser, Columbia, and Sacramento rivers. In the Fraser River, they are distributed from the river mouth upstream past the Morkill River, northwest of McBride. They also occur in the lower reaches of large tributaries, such as the Harrison, Nechako, and Stuart rivers, and in large lakes, such as Fraser, Takla, Trembleur, Stuart, Williams, and Harrison lakes (COSEWIC 2003b).



21

White sturgeon in the lower Fraser River are considered anadromous, with limited migration into marine waters and juvenile rearing in the estuary (COSEWIC 2003b). They are long-lived (>100 years), with delayed sexual maturity, and high first-year mortality (Hatfield et al. 2004). Spawning occurs in the meandering reach of the lower Fraser River from the confluence of the Sumas River upstream to the Coquihalla River; there is no evidence of spawning in the tidally influenced river mainstem (Levings and Nelson 2003). Spawning occurs during peak freshet (from May to July; COSEWIC 2003b, Hatfield et al. 2004) in side-channels and large tributary river fans, in low-velocity near-bed flows, over gravel, cobble, and sand (Levings and Nelson 2003, Perrin et al. 2003).

After hatching, larvae remain near the riverbed in close proximity to spawning habitat, where they feed on zooplankton and dipteran chironomids (Perrin et al. 2003). Juvenile white sturgeon disperse more readily into feeding, and overwintering habitats (Fraser River White Sturgeon Working Group 2005). They rear in the lower reaches of tributaries, large backwaters, side-channels, and sloughs throughout the lower Fraser River (Glova et al. 2008). Higher catches of juvenile white sturgeon have been reported from the Annacis Channel and Hatzic Slough, and to some extent from the Port Mann Bridge, Stave and Matsqui areas (Glova et al. 2008). Near the study area, white sturgeon have been reported from the BC Ferries Fraser Shipyards in the South Arm, the main river channel off Deas Island, immediately upstream of the Tunnel crossing, and upper Deas Slough (Levings and Nelson 2003, Glova et al. 2008). Juveniles rear in a wide range of water depths (1.3 to 6.0 m), but more commonly are found in slow-flowing areas less than five metres deep with fine substrates in side channels, side pools, backwaters and nearshore mainstem open channels (Glova et al. 2008).

Although adult white sturgeon may briefly move into shallower areas to feed during spring and summer, they are typically found in deep nearshore areas, adjacent to heavy flows, defined by deposits of sand and fine gravel with backwater and eddy flow characteristics (COSEWIC 2003b). Important spring and summer feeding areas include the Matsqui Channel and Hatzic Eddy upstream of Mission, as well as the mouth of the Pitt River, and the waters at the Port Mann Bridge, Barnston, Douglas, and Annacis islands (Glova et al. 2010). Adult white sturgeon are mainly piscivorous, and feed primarily on eulachon, salmon, and cyprinids (Lane and Rosenau 1995). As water temperatures decrease in the fall and winter, white sturgeon migrate to overwintering areas where they likely become sedentary and congregate in densely spaced groups (Neufeld et al. 2010, Ghilarducci and Reeve 2012). Overwintering habitats include areas of deeper, slow-moving water, widely scattered from Deas Island to the Sumas River confluence (Neufeld et al. 2010, Ghilarducci and Reeve 2012).



22

The lower Fraser River population of white sturgeon was down-listed to Threatened by COSEWIC in 2012 from the 2003 designation of Endangered (COSEWIC 2003b). It is provincially Red-listed (B.C. CDC 2015). White sturgeon in the lower Fraser River underwent historic fishery removals in the early 1900s, which significantly reduced the population (Walters et al. 2005). However, the population appears to be recovering as a result of ongoing fisheries management (Walters et al. 2005). A commercial fishery in the lower Fraser River no longer exists (Fraser River White Sturgeon Working Group 2009). Since 1994, commercial gill net fisheries are not permitted to take sturgeon, and First Nations are discouraged from taking sturgeon unless the fish died in their nets. Also since 1994, sturgeon caught recreationally in the tidal and non-tidal waters of the lower Fraser River must be released (Fraser River White Sturgeon Working Group 2009).

Green Sturgeon

Green sturgeon (A. medirostris) in B.C. span the entire coast (Scott and Crossman 1973). The extent of freshwater habitat use is unknown (COSEWIC 2004). Since 1985, there have been about 15 to 20 reports of green sturgeon in the lower Fraser River, from the river mouth to 90 km upstream. There is no evidence that spawning has ever occurred in Canadian rivers (COSEWIC 2004). Green sturgeon are long-lived, slow-growing, and reach sexual maturity at an advanced age (Houston 1988). They spend their first one to four years in freshwater, and gradually adjust to estuarine conditions as they grow older. They enter the marine environment as sub-adults but maintain estuarine holding areas (COSEWIC 2004). When in the marine environment, green sturgeon are thought to undergo a northern migration. Green sturgeon in B.C. are thought to originate from spawning populations in the U.S. (COSEWIC 2004). Green sturgeon have been caught incidentally in large bottom-trawl hauls in the Strait of Georgia, and in salmon gill nets at the mouth of the Fraser River (COSEWIC 2004). Habitat requirements in brackish environments are thought to resemble those of white sturgeon (COSEWIC 2004).

COSEWIC re-assessed the status of green sturgeon in 2013 and maintained its designation as species of Special Concern (COSEWIC 2014). The species is listed as Special Concern under Schedule 1 of the Species at Risk Act (SARA) (Government of Canada 2006), and is provincially Red-listed (B.C. CDC 2015). A comprehensive population size and trends analysis has not been done for the green sturgeon population in Canada. However, catch information, which is largely anecdotal prior to 1996, may indicate that the green sturgeon population has suffered a decline over the past few decades (COSEWIC 2014).



23

Eulachon

A small, schooling, anadromous fish species, eulachon return to the lower Fraser River to spawn when they are three to four years of age (Cambria Gordon Ltd. 2006). Spawning migration spans from mid-March to mid-May (Hay and McCarter 2000, LGL and Terra Remote Sensing 2009). Spawning occurs in the river mainstem and occasionally in large tributaries, from Deas Island to Mission, but spawning locations vary among years (Hay and McCarter 2000, Hay et al. 2002). Due to inter-annual variation in spawning locations, the entire lower Fraser River is considered to contain suitable spawning habitat for eulachon (B. Ennevor, Fisheries Resource Manager, DFO, personal communication, January 6, 2014).

Preferred spawning habitat is located in areas of relatively slow current (<0.7 m/s), on plateaus or edges composed of stable fine-medium and coarse sand, pebbles, and gravel, in depths of less than seven metres (LGL and Terra Remote Sensing 2009). To reach spawning habitat, eulachon transit through areas of relatively slow current that are five to 12 m deep and with stable sandy substrates (LGL and Terra Remote Sensing 2009). Immediately after hatching, larvae are rapidly flushed to sea, where they remain in low-salinity surface waters of the Fraser River estuary and rear for several weeks or longer (Hay and McCarter 2000). Juvenile, sub-adult, and adult eulachon exhibit schooling behaviour and live near the ocean bottom at depths of 20 to 150 m (Hay and McCarter 2000). When eulachon reach maturity, and prior to entering the river, they hold in brackish water while making physiological changes that allow them to survive in fresh water.

Eulachon (Central Pacific Coast and Fraser River populations) were designated in 2011 by COSEWIC as Endangered (COSEWIC 2011), and are provincially Blue-listed (B.C. CDC 2015). The Fraser River and Central Pacific Coast populations of eulachon are currently being considered for listing as Endangered under SARA (DFO 2014c). Although historically very abundant, eulachon returning to the lower Fraser River began declining steadily in the mid-1940s, and exhibited a steeper decline in the 2000s (Moody 2008, Schweigert et al. 2012). Commercial and recreational harvesting of eulachon in the Fraser River have been suspended since the early 2000s, and only a very small Aboriginal ceremonial fishery continues today (Schweigert et al. 2012).

Coastal Cutthroat Trout

Coastal cutthroat trout are found in a wide range of habitats. In B.C., they inhabit low-elevation lakes and rivers along much of the coast, including streams in the Fraser River basin. Inland penetration is generally less than 150 km (Costello 2008). Their relatively small size at maturity allows them to use smaller streams than other salmonids (Slaney and Roberts 2005).

The Fraser River, including its tributary streams, supports all cutthroat life history forms. These include resident forms in headwater streams that exhibit little instream movement, river-run forms that move between small spawning-rearing tributaries and large river mainstem foraging areas, lake-run forms that migrate between lakes and foraging/spawning areas instream, and anadromous (sea-run) forms that migrate to the estuary or the ocean for less than a year before returning to fresh water to spawn (Slaney and Roberts 2005). Sloughs and backwaters along the lower Fraser River mainstem provide rearing, overwintering, and migratory habitat for anadromous, river-run, and (potentially) lake-run cutthroat trout.

Unlike Pacific salmon, but consistent with other trout and char, coastal cutthroat trout are able to spawn multiple times in successive years. Spawning usually occurs from late winter to spring (McPhail 2007), though sea-run populations have also been known to spawn during the fall (McPhail 2007). Spawning typically occurs in small, low-gradient streams (Hartman and Gill 1968), in pool tail-outs with gravel substrate ranging from 5 mm to 50 mm (Slaney and Roberts 2005). Newly hatched alevins remain in gravel until fry emerge, usually between March and June (Trotter 1997). Fry initially occupy microhabitats with low flow levels, gradually moving into deeper microhabitats with higher flow and more cover, such as large woody debris, streambank root masses, instream and overhanging vegetation (Solazzi et al. 2000, Slaney and Roberts 2005).

Depending on the life-history form, adults either remain in the natal stream, or migrate to lakes or larger river systems to forage before returning to spawn. Sea-run cutthroat stay in freshwater systems for one to five years before migrating to the ocean (Trotter 1997, Slaney and Roberts 2005), between the months of March to June (Slaney and Roberts 2005). While at sea, coastal cutthroat trout remain close to shore before returning to fresh water in the spring (Trotter 1989). Generation time for coastal cutthroat trout is three to five years (Peterson and Fausch 2008).

Coastal cutthroat trout are primarily carnivores, though their diet varies by life form and life history stage. Fry feed on small prey, particularly chironomid larvae (Glova 1984). Resident form adults feed primarily on insects, whereas lacustrine form adults tend to feed on a wider variety of prey, including zooplankton and small fish (McPhail 2007). In the ocean, sea-run cutthroat feed on small fish, and invertebrates including amphipods, isopods, decapods, and euphausiids (Trotter 1989, Brodeur and Pearcy 1990).

Coastal cutthroat trout (ssp. clarkii) are provincially Blue-listed (B.C. CDC 2015). Population sizes of coastal cutthroat trout are typically in the order of tens to hundreds of individuals, even in the largest systems. As a result, cutthroat populations are susceptible to disturbance (e.g., logging, resource extraction, urban development, stream channelization), particularly



25

when it leads to impairment of habitat quality (Costello 2008). Historically, coastal cutthroat trout have supported diverse and regionally important sport fisheries throughout the Fraser River basin. Although increasingly restrictive fishing regulations have come into effect, angling pressure has likely been another significant factor limiting natural coastal cutthroat production, particularly near urban areas (Post et al. 2002).

Rainbow/Steelhead Trout

Rainbow trout occur in two life history forms, based primarily on where they spend their time feeding and maturing. Stream resident rainbow trout reside entirely in fresh water. Fish of the second form, known as steelhead, are anadromous. Steelhead leave fresh water as juveniles and migrate into the ocean where they grow to maturity before migrating back to their natal spawning grounds (Barnhart 1986). Larger streams with steep gradients emptying directly into the ocean usually support steelhead trout, as do larger rivers, such as the Fraser River (Hartman and Gill 1968). Spawning occurs in spring (February through June) over shallow gravel riffles of a river mainstem or a suitable clear water stream (Barnhart 1986). Hatching occurs approximately within three to four weeks. By mid-summer, fry emerge from the gravel and rear in fresh water for two to five years before smolting and migrating to the ocean (Barnhart 1986). Newly emerged fry rear in shallow depths and over small gravel substrates, and move into deeper and faster-flowing habitats as they grow (Roberge et al. 2002). Yearlings and larger juveniles are associated with large substrates and relatively deep and fast-flowing waters (Rempel et al. 2012). Juvenile steelhead smolts migrate to salt water between late April and mid-June, where they feed and grow rapidly (Levy and Parkinson 2014). Upon maturity, steelhead return to their natal streams to spawn, and spawning occurs more than once (Levy and Parkinson 2014). Spent spawners migrate to the ocean to feed and may return to their spawning grounds within the same year, or skip a year before spawning again (Levy and Parkinson 2014).

Rainbow/steelhead trout are not provincially or federally listed. However, wild steelhead stocks in the lower Fraser River have declined to 30 per cent of estimated carrying capacity since the early 1990s, largely due to reduced ocean survival and impaired freshwater habitat quality (Lill 2002). Fisheries restrictions and area closures have led to a reduction of angling pressure. Fishing tends to be restricted to recreational fisheries, as well as limited and localized Aboriginal harvesting (Beacham et al. 2004). Steelhead are also incidentally caught in salmon fisheries (Beacham et al. 2004). In the early 2000s, the Greater Georgia Basin Steelhead Recovery Action Plan was initiated with the primary objective to stabilize and restore wild steelhead stocks and habitats within the lower Fraser River (Lill 2002). Initiatives within the action plan include habitat protection and restoration, stream enrichment, as well as research including stock assessment (Lill 2002).

Dolly Varden

Dolly Varden (Salvelinus malma) are found in coastal areas of the Pacific Ocean from Washington to Southeast Alaska. In B.C., Dolly Varden can be found in most coastal drainages, and are associated with cool-body watersheds (McPhail 2007). Dolly Varden are largely a coastal and anadromous species entering the ocean regularly, with distribution of this species not typically extending far inland (i.e., past Hope, within the Fraser River system) (McPhail 2007). Dolly Varden are commonly smaller than bull trout (S. confluentus), inhabiting small streams and feeding primarily on drift. In contrast, bull trout (described below) are typically larger, piscivorous, inhabiting cool waters throughout the interior, and generally absent from shorter coastal rivers (McPhail 2007). Where distributions overlap, Dolly Varden and bull trout coexist, without extensive hybridization (McPhail and Baxter 1996). Within B.C., their geographic ranges overlap in northern and western-central Coast Mountain drainages, and in the lower Fraser Valley (McPhail and Baxter 1996).

Dolly Varden occurs in three life-history forms: an anadromous form that migrates between freshwater streams and the ocean, a stream-resident form that remains in rivers and streams for most of its life, and a lake-run form that remains within a single freshwater body and spawns in adjacent streams (McPhail 2007).

Spawning occurs in autumn within headwaters of small streams. Females lay between 70 and 500 eggs, in pool tail-outs (McPhail 2007). Fry emerge from the gravel in spring (April/May), with juveniles remaining in the stream for two to four years (Armstrong 1970). Juveniles use a variety of habitats, including areas of still or moving water, with gravel or muddy substrates having dense instream vegetation, or open water with little or no instream complexity (Armstrong and Morrow 1980). Large rivers are important as overwintering habitats for larger juveniles, as well as sub-adult anadromous Dolly Varden. The lower Fraser River is likely used as a migratory corridor by Dolly Varden, due to its proximity to nearshore estuarine and coastal feeding and overwintering grounds.

Dolly Varden smolts migrate to the ocean in spring and may remain for only two to four months before returning to fresh water (Armstrong and Morrow 1980), where they feed on the eggs and flesh of decaying salmon (Bond and Quinn 2013). Alternatively, Dolly Varden may remain in marine waters well into the fall months, returning only for spawning or overwintering in freshwater habitats (Bond and Quinn 2013). Spawning can occur over multiple years, but does not necessarily occur in successive years (Mochnacz et al. 2010). Dolly Varden movement patterns are complex and often influenced by a combination of age, size, or maturational state, and the relative abundance of resources in marine and fresh waters. Local environmental



27

conditions influence the relative benefit of each habitat, and Dolly Varden may respond with flexibility in the timing of movements among habitats (Bond and Quinn 2013). Generation time for Dolly Varden is five years (Scott and Crossman 1973).

The diet of Dolly Varden varies with life history stages, and is also apparently influenced by the presence of competing fish species. The stream-resident form tends to feed near the bottom of creeks on nymphs and larvae of aquatic insects, with diet shifting to larger prey as fish grow (McPhail 2007). The lake-run form feeds on zooplankton, shifting to benthos found on the lake floor when trout are present (McPhail 2007). Sea-run Dolly Varden feed on macroinvertebrates, juvenile salmon, and other species of fish (Armstrong 1965).

Dolly Varden are not provincially or federally listed. Although population sizes within the Fraser River basin are largely unknown, Dolly Varden are thought to be susceptible to disturbance (e.g., logging, resource extraction, urban development, stream channelization), particularly when it degrades habitat quality and reduces availability of suitable spawning and rearing habitat (COSEWIC 2010). Dolly Varden have and continue to support diverse and regionally important sport fisheries throughout the Fraser River basin.

Bull Trout

Bull trout are endemic to western Canada and the U.S. Pacific Northwest. The species' current distribution extends from the Oregon-California border and northern Nevada, north to southern Yukon, and southwestern Northwest Territories (McPhail 2007). Although bull trout reach the Pacific coast (B.C. Fraser and Squamish River drainages; Washington: Skagit River drainage, Olympic Peninsula), they are generally restricted to interior drainages (COSEWIC 2012). In B.C., bull trout are found in the cool waters of most major interior watersheds (i.e., upper Columbia, Peace, Liard, and Yukon River drainages), and in major coastal watersheds that penetrate into the interior (Fraser, Homathko, Klinaklini, Skeena, Nass, Iskut-Stikine, and Taku River drainages) (McPhail 2007).

Of the salmonids present within the Fraser River watershed, bull trout are notably a cold water species generally found in waters below 18°C and most commonly in temperatures less than 12°C (Dunham et al. 2003). They exhibit variable life histories (McPhail and Baxter 1996, McPhail 2007), including stream resident, adfluvial (lake-run), large river (fluvial), and sea-run.

Stream resident bull trout are typically associated with high gradient, headwater streams in mountainous regions. They are usually separated from other populations by barrier (e.g., falls, velocity barriers, high temperature) (McPhail and Baxter 1996, McPhail 2007). Stream resident bull trout are non-migratory, and spend their entire life in small streams (McPhail and Baxter 1996, McPhail 2007).



28

Adfluvial bull trout migrate between lakes or reservoirs and tributary rivers or streams where they spawn. Spawning can also occur in the inlet or outlet of lakes (Carl et al. 1989). In lakes, adults forage in the littoral zone in the fall and spring, and move to deeper water in the summer, most likely due to temperature constraints (McPhail and Baxter 1996).

Fluvial bull trout live in large rivers and major tributaries, and often migrate to smaller rivers or streams to spawn. Adult bull trout tend to concentrate in cooler areas of the river mainstem, and are often associated with the mouths of spawning streams (McPhail and Baxter 1996, McPhail 2007). Some fluvial bull trout populations are anadromous, and spend part of their life at sea.

Anadromous bull trout populations are suspected to occur in the Squamish and lower Fraser rivers (McPhail and Baxter 1996, McPhail 2007). Because anadromous char populations occur where bull trout and Dolly Varden overlap, evidence that these char are bull trout rather than Dolly Varden is often circumstantial. One char tagged in the Squamish River was recaptured in the Skagit River, after a journey of about 150 km through the Strait of Georgia. Also, tagged char in the Pitt River above Pitt Lake have been recaptured in the Fraser River estuary (McPhail and Baxter 1996).

Bull trout spawn in shallow stream habitats characterized by relatively low gradient, a predominance of small gravel (<20 mm), relatively low water velocity (0.03-0.80 m/s), and proximity to cover (e.g., cut banks, log jams, pools, overhanging vegetation) (McPhail and Baxter 1996). Spawning occurs in the fall, when water temperatures drop below 9°C, which is likely the cue to initiate redd building and spawning behaviour (McPhail and Baxter 1996). Egg incubation occurs during the winter, and fry emerge from the gravel in early spring (mid-April to mid-May) (McPhail and Baxter 1996). Bull trout fry are closely associated with shallow edges of rivers and streams, especially in areas of large, loose gravel, where they use the interstitial habitat for cover (McPhail and Baxter 1996).

Juvenile bull trout rear in spawning streams for at least two years before migrating to the larger rivers, or the ocean, depending on the form (Pratt 1992, McPhail and Baxter 1996). In fresh water, juvenile bull trout tend to shift to deeper, slower-flowing water in the fall, where they stay in contact with coarse substrates and remain closer to cover, which provides ice-free refuge throughout winter (COSEWIC 2012). They forage near the substrate and in the water column, but not at the surface (McPhail and Baxter 1996). As they grow, juveniles shift their diet from benthic organisms and drift to small fish, such as sculpins, mountain whitefish, and trout fry (Pratt 1992).



29

Migratory forms seek suitable feeding and overwintering habitat in larger streams and rivers, as well as nearshore coastal areas (COSEWIC 2012). After spawning, bull trout move to overwintering habitats by September or October (Hayes et al. 2011, COSEWIC 2012). The lower Fraser River is likely used as a migratory corridor by bull trout, due to its proximity to nearshore estuarine and coastal feeding and overwintering grounds. Generation time for bull trout is five to seven years (Rieman and Allendorf 2001).

Bull trout are provincially Blue-listed and were designated by COSEWIC in 2012 as being of Special Concern (B.C. CDC 2015). Bull trout populations found in the south coast region of B.C. are currently being considered for listing as species of Special Concern under SARA (DFO 2014d). In B.C., bull trout populations are thought to be diminishing (Hammond 2004). Limiting factors include habitat fragmentation resulting from development associated with resource extraction and logging activities, as well as degradation of habitat quality such as through obstruction to movement, stream channel instability, sedimentations, lack of cover, or increasing water temperatures (Hammond 2004). Furthermore, increasing angling effort may pose additional pressure to diminishing bull trout populations, as new roads allows access to streams that were previously remote (Hammond 2004).

Deas Slough 4.2.1.4

Hydrology and Hydraulics

Deas Slough is a backwater feature of the lower Fraser River South Arm. The slough was formerly a side arm of the river that was dammed off at its upstream end in 1949 (Birtwell et al. 1987a). It is situated about 15 km upstream from the Fraser River mouth at Sand Heads. It is approximately 2,700 m long, 250 m wide, with an average depth of five metres (Birtwell et al. 1987a). Some deeper sections exist in dredged locations in front of the two marinas situated on, and occupying about one-third of the shore of the slough’s south bank (Birtwell et al. 1987a).

In contrast to riverine areas in the South Arm where the riverbed is dominated by sandy substrate, the bottom material in the slough is predominantly silt and clay (Birtwell et al. 1987a). Infrequent and localized dredging takes place to maintain access to small craft harbours and moorage (FREMP 2006). Recent dredging (February 2014) was initiated in lower Deas Slough to re-establish the depth and width of the navigation channel, and to remove materials around the Ferry Road boat ramp that had been affecting recreational boating activity (PMV 2014b). By November 2014, approximately 60,000 m3 of river bottom were removed by cutter suction and disposed of via in-river dispersal (PMV 2015).



30

Deas Slough is tidally influenced, with salt water intrusion during the winter freshwater low-flow period, resulting in vertical stratification of the water column. Salinities at depth increase progressively as freshwater flows decrease. However, a sill at the mouth of Deas Slough prevents saline penetration in water greater than four metres deep; thus, salinity at depth is not as high (i.e., approximately 10 practical salinity units) as that recorded in the river just outside the slough, which often reaches 26 practical salinity units (Birtwell et al. 1987a). Stratified conditions in the deeper pockets of the slough are also associated with low levels of dissolved oxygen, and reduced oxidation-reduction potential likely due to low photosynthetic activity, and higher pH (ranging from 6.4 to 8.2), also reflecting the influence of salt water (Birtwell et al. 1987a).

With the onset of freshet, increased river flows reduce salt water intrusion, with low salinity levels characterizing slough waters throughout the water column (Birtwell et al. 1987a). Influx of turbid fresh water reduces water clarity of the slough’s surface water; however, DO levels are generally high (Birtwell et al. 1987a). With the progression of freshet, oxidation-reduction potential also rises in response to increased photosynthetic activity (Birtwell et al. 1987a).

Physical Fish Habitat

The shoreline along Deas Slough is designated primarily as highly productive (red-coded) habitat (BIEAP - FREMP 2014). The intertidal bench transitions shoreward from a mudflat into a brackish marsh, with varying width from approximately 10 m along the north and south banks to approximately 200 m at the upstream end of the slough near the Delta Deas Rowing Club, and on either side of the Deas Slough Bridge north support pier (BIEAP - FREMP 2014). Marsh vegetation is dominated by hard-stemmed bulrush (Schoenoplectus acutus), Arctic rush (Juncus

arcticus), Lyngbye’s sedge (Carex lyngbyei), and common cattail (Typha latifolia) (BIEAP - FREMP 2014). Riparian vegetation backing the marsh along the north and east banks of Deas Slough consists of reed canary grass (Phalaris arundinacea), and shrub species such as hardhack (Spiraea douglasii) (BIEAP - FREMP 2014). The riparian zone on the south bank is narrow and confined to the crest and slope of the dike, consisting primarily of mowed grass and clumps of Himalayan blackberry (Rubus armeniacus) (BIEAP - FREMP 2014).

Deas Island is a Metro Vancouver regional park and defines the slough’s north bank. Most of the areas south of the slough are farmland (grass, crops). Some of the land is below sea level, and is intersected by ditches to facilitate drainage (Birtwell et al. 1987a). Within the park, as well as immediately upstream of the Deas Slough Bridge south support pier, upland vegetation consists of deciduous, mixed, and coniferous tree woodland (BIEAP - FREMP 2014) dominated by black cottonwood, with an understory of red alder and willow, a shrub layer of salmonberry (R. spectabilis) and blackberry, as well as salal (Gaultheria shallon), and huckleberry (Vaccinium sp.) (Birtwell et al. 1987a).



31

Intertidal habitat of low (green-coded) to moderate (yellow-coded) productivity also occurs in Deas Slough (Appendix A, Figure 3; BIEAP - FREMP 2014) described as follows:

A short (about 50 m) section of shoreline at the upstream end of the slough at the Delta Deas Rowing Club pier, as well as approximately 300 m of shoreline fronting the Deas Island Yacht Club marina on the south bank, are classified as habitat of moderate productivity (yellow-coded).

Riprap-armoured shoreline in the vicinity of support piers and pedestals of the existing Deas Slough Bridge on the north and south banks of the slough is characterized as habitat of low (green-coded) to moderate (yellow-coded) productivity.

The shoreline fronting the dock, boat launch, and haul-out area at the Captain’s Cove marina on the south bank of the mouth of Deas Slough is characterized as low-productivity habitat (green-coded).

Aquatic Resources

The vertically stratified nature of Deas Slough perpetuates a shallow, productive, low-salinity environment that is used for rearing and overwintering by a number of fish species. Deas Slough is important rearing habitat for underyearling sockeye salmon, which are present in the slough from April to October, with maximum abundance in late June and late July (Birtwell et al. 1987b). Underyearling starry flounder also rear in the lower and, to a lesser extent, in upper Deas Slough in spring and summer, while adult starry flounder are present in the slough in the autumn and winter (Birtwell et al. 1993). Other fish species that have been recorded in Deas Slough include chinook, chum, coho, and pink salmon, prickly sculpin, Pacific staghorn sculpin (Leptocottus armatus), slimy sculpin (C. cognatus), largescale sucker (Catostomus

macrocheilus), northern pikeminnow, peamouth, redside shiner, threespine stickleback, longfin smelt (Spirinchus thaleichthys), white sturgeon, mountain whitefish (Prosopium williamsoni), and the non-native American shad (Alosa sapidissima) (FISS 2014). Refer to Section 4.2.1 for summaries of the biology, habitat requirements, and status of Pacific salmon, sturgeon, eulachon, trout, and char.

Green Slough 4.2.1.5

Hydrology and Hydraulics

Green Slough drains into the lower Deas Slough and ultimately into the lower Fraser River South Arm. The channel parallels Highway 99 for approximately 155 m from its confluence with Deas Slough until it bends southwest along River Road West for approximately 1.2 km to the Westminster Avenue junction in Delta. Green Slough is outside of Delta’s Fraser River dikes; therefore, it is tidally influenced, and flows into the Fraser River are not impeded. The Green Slough pumping station located at 5596 River Road drains agricultural and residential runoff from Crescent Slough into Green Slough.



32

Green Slough is 15 m to 20 m wide along most of its length, although channel width narrows to about 10 m near the pump station. The channel is characterized as a very low-gradient glide, with fairly uniform depths that range from about 0.9 m to 1.5 m. Water levels and flows are relatively stable throughout the year with no surface turbulence, providing perennially wetted fish habitat. The substrate consists predominantly of fines (silt).

The Green Slough pump station consists of two flood boxes and four pumps of a combined capacity of 6.25 m3/s (LGL et al. 2009). The pumps are not screened to prevent fish entrainment, and no fish deflection or entrainment prevention devices are employed at the station (LGL et al. 2009). The pump station is run in two modes: drainage occurs from late September/late November to mid-May/early June to provide flood protection, while irrigation occurs from mid-May/early June to late September/late November to provide agricultural water supply. The side-hinged flood box flap gates are operated using head differential between the upstream and downstream water levers. They typically close whenever water levels are higher downstream than upstream, i.e., on rising tides (LGL et al. 2009). Slough water levels are manipulated by means of chaining shut the flap gates, inserting stop logs into the flood boxes, or opening a sluice gate or flap gate inset to allow for limited water exchange (LGL et al. 2009). As part of the Delta Irrigation Enhancement Project, the operation of this pump station was modestly modified in 2013 to provide enhanced upstream fish access.


Green Slough is classified as an environmentally sensitive area (ESA) under Delta’s Official Community Plan. An ESA designation identifies areas of high environmental value requiring protection or mitigation of environmental impacts for any proposed development. As a backwater feature that is tidally influenced, Green Slough provides perennially wetted rearing and overwintering salmonid habitat (LGL et al. 2009). Along Green Slough's length, the riparian buffer is 30 m wide, and overhanging vegetation is ample; however, since it is a very low-gradient glide with a predominance of fines, Green Slough does not offer valuable salmon spawning habitat (LGL et al. 2009).

The shoreline of Green Slough is classified as habitat of high productivity (red-coded) (BIEAP - FREMP 2014). A tidal marsh comprises the lower elevations of the intertidal bench, with vegetation consisting of Lyngbye’s sedge, hard-stemmed bulrush, scouring rush (Equisetum

hyemale), and the non-native purple loosestrife (Lythrum salicaria) (BIEAP - FREMP 2014). Riparian vegetation backing the marsh consists of low and tall shrubs of hardhack, red-osier dogwood (Cornus stolonifera), non-native Himalayan blackberry and Scotch broom (Cytisus

scoparius), with isolated areas with black cottonwood (BIEAP - FREMP 2014).



33

At EastpointPark Reserve, immediately downstream of the Green Slough pump station, marsh habitat was created and the riparian zone was restored with plantings of native vegetation, to compensate for loss of riparian and mudflat habitat as a result of riprap installation and sheet piling in Green Slough during bridge construction at Admiral Blvd (BIEAP - FREMP 2014). Tidal flows were also improved by removing an old wooden culvert that had collapsed (BIEAP - FREMP 2014).

Compensation works were also undertaken in 1997 at the mouth of Green Slough to restore habitat that was disturbed during upgrade and maintenance works within the existing Captain’s Cove Marina Ltd. marina facility. Compensation included the creation of an intertidal marsh bench, as well as riparian plantings on top of riprap slope (BIEAP - FREMP 2014).

Aquatic Resources

Fish passage into Green Slough is unobstructed. Although salmonid spawning values do not apply, this backwater feature is expected to provide high-value rearing and overwintering habitat for fish, including Pacific salmon, particularly coho and chinook (LGL et al. 2009). Habitat values for salmonids upstream of the flood box and pump station at the confluence with Crescent Slough is anticipated to be relatively low, given impeded fish access, water withdrawal for agricultural use, and high water temperatures in the summer (LGL et al. 2009).

Historical records of cutthroat trout from Crescent Slough exist from 1983 (FISS 2014); however, no salmonids have been detected in the slough since then. Green Slough is also used by non-salmonid species, such as threespine stickleback, prickly sculpin, redside shiner, peamouth, and brassy minnow (Hybognathus hankinsoni) (FISS 2014). Non-native fish species also reported from Green Slough include brown catfish, black crappie, pumpkinseed (Lepomis

gibbosus), carp, goldfish (Carassius auratus), and largemouth bass (Micropterus salmoides) (FISS 2014). Refer to Section 4.2.1 for summaries of the biology, habitat requirements, and status of Pacific salmon, sturgeon, eulachon, trout, and char.

Detailed habitat assessments were conducted at 33 of 106 minor upland watercourses (Appendix B, Table 3) as well as Green Slough. The remaining 73 were assessed using photographs taken in the field and from imagery available online through City of Richmond (Richmond 2014) and DeltaMap (Delta 2002, 2003a, b, 2012). Ditches and sloughs within the study area are low-gradient (≤0.5 per cent) with fine sediment substrates. Mesohabitats consist solely of straight runs without any pools or riffles. Overall instream cover was found to be generally limited (absent at 13 sites, trace at 48 sites, and moderate at 42 sites), with the exception of four sites that have abundant cover, i.e., Westminster Highway Ditch South, east of Highway 99; Highway 99 Ditch Southwest (between 64 St and Highway 17); and Burns Drive Cross-Ditch #1. The main cover observed in these watercourses is overhanging and instream vegetation. Instream features provided trace cover at only few sites: trace cover provided by small or large woody debris, deep pools, and undercut banks occur at 11, 12, and 11 sites, respectively. Ninety-three of 107 sites have either no or less than 20 per cent crown closure, nine sites have less than 40 per cent, four have less than 70 per cent, and one has greater than 90 per cent. Riparian vegetation was observed to consist mainly of grassed roadside shoulders, shrubs lining ditch banks, and adjacent agricultural fields.

In Situ Water Quality

Table 4-2 summarizes the spring, summer, and autumn water quality data from upland watercourses sampled within the study area, in relation to the B.C. WQG criteria for temperature, DO, and pH. Water quality data are provided in Appendix B, Tables 4 through 6.

All sites sampled in the spring and autumn met the B.C. WQG criteria for temperature; however, all of the sites sampled in summer exceeded the criteria. Dissolved oxygen (DO) concentrations were below the water quality guidelines for at all sites sampled in spring and summer, aside from three in the spring sampling, four in the summer, and 7 in the autumn. The B.C. WQG criteria for pH were met for nine of 25 sites sampled in spring, 13 of 15 sites sampled in the summer summer, and 11 of 34 sites sampled in autumn. Conductivity varied across sites but was generally low.

Fish Presence and Distribution

Including Crescent Slough, fish presence has been previously documented in 39 of the assessed upland watercourses within the study area (Delta 2002, 2003a, FISS 2014). Crescent Slough and Big Slough are the only watercourses with historic records of CRA species (i.e., cutthroat trout, chinook and coho salmon); however, these capture dates are from 1983 (FISS 2014), and this watercourse is generally considered to be non-salmonid bearing, especially within reaches close to the Highway 99 ROW (Hemmera 2006).

During the spring sampling period, 88 minnow traps were set at 26 sites within the study area for a total of 1,971 hours of sampling effort. In autumn, 88 traps were set in 34 watercourses for a total of 1,994 hours of sampling effort. Species captured include the native species brassy minnow and threespine stickleback, and the non-native brown catfish, goldfish, and pumpkinseed. Historic and recent fish capture data for the study area are summarized in Table 4-3.

The City of Richmond classifies ditches along the west side of Highway 99 south of Westminster Highway flowing towards the Fraser River South Arm as salmon-bearing. Along the east side of Highway 99, salmon-bearing status is assigned to ditches south of Bridgeport Road to Steveston Highway. However, no salmonid species have been previously documented within Richmond ditches (FISS 2014), and extensive sampling efforts in the study area in 2014 did not result in capture of salmonids. Connectivity of these ditches to the Fraser River South Arm appears to be very limited by the presence of pump stations and flood boxes. Located at the south end of Highway 99 Ditch West (between Steveston Highway and Fraser River), and at the intersection of Steveston Highway and No. 6 Road, this flood-control infrastructure appears to pose considerable restrictions to salmonid access into this ditch network. Connectivity and distance of the watercourses from the Fraser River South Arm are also expected to limit access and use. Classification of these watercourses according to the codes and definitions presented in Table 3-2 reflects these limitations on fish access, results of fish sampling efforts in 2014, and low fish habitat values, which includes relatively poor water quality observed in ditches within the study area.

North of the Fraser River South Arm, Highway 99 Ditch West (between Steveston Highway and Fraser River South Arm) is classified as dashed-red, and Highway 99 Ditch East (between Steveston Highway and Fraser River South Arm) as yellow. Jacobsen Way/Hartnell Road Ditch is also classified as dashed-red, because it has the potential to flow directly into Highway 99 Ditch West (between Steveston Highway and Fraser River) (Appendix A, Figure 1f). North of Steveston Highway, Highway 99 ditches are classified as orange until King Road, and yellow north of that location (Appendix A, Figure 1b-1f).

South of Fraser River South Arm and its well-connected Deas and Green sloughs, Delta catchment areas FA-5 and FA-5 overlap with the study area and have some potential to support salmonid species, such as cutthroat trout. Salmonid presence was documented more than 30 years ago (Delta 2003a, FISS 2014); however, previous sampling conducted for the Ministry’s South Fraser Perimeter Road (SFPR) project and sampling efforts applied in 2014 did not result in the capture of any salmonids. Access to these Delta ditches by salmonids from the Lower Fraser River/Green Slough is likely impaired by flood-control infrastructure. Flows into Crescent Slough are limited by a flood box and pump station at the confluence with Green Slough (LGL et al. 2009). In classifying these ditches, consideration was given to distance from Green Slough. Ditches from Deas Slough to Highway 17A are therefore classified as dashed-red; ditches east of Highway 17A are not continuous with those west of Highway 17A and are classified as yellow and orange.

4.3 Incidental Observations

Incidental observations include aquatic and terrestrial wildlife other than fish that were either captured in minnow traps or observed during the course of the field work. Amphibian captures include the non-native American bullfrog (Lithobates catesbeianus), green frog (L. clamatans), and northwestern salamander (Ambystoma gracile). Invertebrate captures include dragonfly naiads (Aeshna sp.), water beetles, aquatic snails, and leeches (Table 4-4).

5.0 Discussion

The major results arising from the information review and field freshwater fish and fish habitat study of existing conditions are discussed below.

5.1 Key Findings

5.1.1 Commercial, Recreational, or Aboriginal Fish Values

The review of existing information confirmed that extensive fish and fish habitat information is available for the major watercourses that intersect the study area, including the lower Fraser River, specifically South Arm, and Deas and Green sloughs. Major watercourses have suitable habitat to meet the life history needs of various fish species that are considered to have CRA fisheries values. The full list of CRA fish species that occur within the study area includes five species of Pacific salmon (coho, chinook, chum, pink, and sockeye), two species of trout (coastal cutthroat, and rainbow/steelhead), two species of char (Dolly Varden and bull trout), two species of sturgeon (green and white), and eulachon.

The Fraser River South Arm and tidal features in the lower river reaches (e.g., Deas and Green sloughs) are well-documented as providing important habitat values for all of the aforementioned CRA fish species. Most notably, the lower river is a significant upstream migration corridor for adult Pacific salmon and a rearing habitat corridor for out-migrating juveniles. Juvenile salmon (especially chinook, chum, and to a lesser extent coho) receive considerable feeding and refuge benefits from key estuarine tidal habitats, in particular tidal marshes and adjacent un-vegetated flats, as they move downstream into the lower estuary. These same river reaches and well-connected tidal backwaters also provide important habitat values for various life history stages of coastal cutthroat trout, rainbow trout (including steelhead), white sturgeon, and eulachon. Adult green sturgeon also potentially occur, but in low numbers and primarily in the lower estuary.

Upland watercourses within the study area comprise mainly roadside or agricultural ditches. Fish access into these ditches is typically limited by flood control infrastructure (i.e., dikes with pump stations and flood boxes), which impacts their connectivity to higher-value CRA fish waters located further downstream. With specific consideration towards salmonids (i.e., Pacific salmon, trout and char), which are the most likely CRA fish to occur in these ditches, low gradients and finer streambed substrates preclude any potential for spawning. The most likely life history stage of salmonids that would inhabit these ditches are juvenile fish, in particular rearing juvenile Pacific salmon (e.g., chinook and coho salmon). Based on fieldwork in 2014, water quality tends to be quite poor seasonally, with relatively high water temperatures, low



52

DO concentrations, and seasonally acidic pH levels. These conditions are expected to preclude or deter the use of these watercourses by rearing salmonids, except during winter months when more suitable water quality conditions may occur.

Although fish sampling occurred at 61 sites during the spring and autumn 2014, when water levels and water quality should have been most suitable for salmonids, no salmonids were caught in upland ditches within the study area.

All of the watercourses within the study area were classified based on a classification scheme that focuses primarily on CRA fisheries values. Watercourse reaches with CRA values are described in this report and mapped in the appended watercourse classification maps (Appendix A) as year-round CRA fish habitats (red-coded), seasonal CRA fish habitats (dashed-red-coded), or as a significant upstream source of food and nutrients to CRA fish habitats (orange-coded). For the upland watercourses, this coding is generally based on potential rather than confirmed CRA fish habitat values. Furthermore, it is noted that potential habitat use by CRA fish is considered to decrease with distance from downstream confirmed CRA fish habitats into which these watercourses drain. This assumption is based on the best professional judgement of this report’s authors; additional fieldwork would be required to more definitely characterize the full distribution of CRA fish.

5.1.2 Non-Commercial, Recreational, or Aboriginal Fish Values

With the exception of major watercourses and a select few minor upland watercourses within the study area, the majority of the remaining watercourses are low-gradient channelized ditches characterized by fine bottom substrates and poor connectivity to downstream CRA waters. Additionally, the use of these watercourses by fish may be limited by poor water quality conditions, in particular high temperatures and low DO levels. In the warmer summer months, these poor water quality conditions would presumably be heightened due to lower flows, higher water temperatures, and lower DO concentrations. As a result, some of these ditches may not support any fish (even resident fish) on a year-round basis.

Numerous different resident fish species have been previously documented within the study area (refer to Appendix B, Table 1); however, fish fauna captured by minnow trapping in 2014 were limited to three native fish species (threespine stickleback, brassy minnow, and bull trout) and two introduced fish species (goldfish and pumpkinseed). All of these fish, in particular threespine stickleback and the three introduced species, are known to be tolerant of poor water quality conditions and therefore are not unexpected within the study area.



53

Based on the watercourse classification scheme developed for this study, non-CRA watercourse reaches are described in this report and mapped in the accompanying watercourse classification maps (Appendix A) as resident fish habitats (yellow-coded) or non-fish bearing habitats (green-coded). The majority of the watercourses overlapping with the Project alignment have non-CRA fish habitat values.
