Preface

The Swan Canning Environmental Monitoring and Reporting project is a long term

monitoring project consisting of regular sampling of the Swan and Canning Rivers

and Swan-Canning catchment, enabling regular water quality reporting and annual

reporting on estuarine and catchment compliance. The project was designed and

implemented in 1994 by the Swan River Trust and Department of Water (then Water

and Rivers Commission) as part of the Swan-Canning Cleanup Program Action Plan.

The project currently falls under the Swan River Trust’s Healthy Rivers Action Plan

and is jointly operated by the Water Science branch of the Department of Water and

the Swan River Trust.

The catchment sampling conducted for this monitoring project is captured under the

Department of Water WIN data management project SG-C-SWANCATCH, consisting

of fortnightly sampling of sixteen sites.

In March 2010 a new catchment sampling project was implemented to address gaps

in existing catchment monitoring and to provide data for predictive modelling of the

Swan-Canning catchment. This catchment sampling consists of fortnightly sampling

of sixteen sites (since April 2012) and falls under the Department of Water WIN data

management project SG-C-SCWQIP (Swan Canning Water Quality Improvement

Plan). Note that this catchment sampling project was initially run from January 2007

to June 2008 as SG-C-SWANCCI but was closed due to limited funding.

Some important catchment sampling changes are listed below:

• Changed from weekly to fortnightly sampling in 2001.

• Changed from specific conductivity (compensated at 25°C) to uncompensated conductivity in October 2001 and back to specific conductivity in September 2006

• Added parameters Dissolved oxygen and pH in September 2006 (changed instrument from WTW to Quanta).

• Added parameters Dissolved organic nitrogen and Total organic carbon in October 2006. Total organic carbon only sampled to July 2008.

• October 2006 Canning River site moved ~550m downstream from McKenzie Grove to Seaforth for better site access and to align with location of gauging station.

• October 2006 extra Ellen brook site (EBAC) added to regular sampling near confluence with Avon River. Stopped sampling March 2009 due to site access issues. Site location changed (SWN9) and sampling restarted March 2010.

• April 2011 SCWQIP Claise Brook site moved from SCCIN5 to CB13.

• May 2011 South Belmont Main Drain site moved ~100m upstream from SWS11 (Great Eastern Hwy) to SWS13 (Severin Walk, Abernathy Rd) due to tidal influence at the old site (SWS11). The gauging station has also been moved (~750m upstream to Cleaver Terrace).



• The Wandoo Creek catchment site was moved downstream to WNDCK (August 2011) as the former site, SCCIN4, was almost always dry, even in winter.

• From April 2012 onwards the SCWQIP sites list was modified and now consists of 16 sites (down from 17); four of which are new sites selected after a period of expanded monitoring where 36 sites were monitored for nine months (Aug 2011 to March 2012).

Summary

This Swan-Canning catchment quarterly data report presents background and

current quarter data collected from a total of fifteen sites from the SWANCATCH

project. Data for the lower Ellen brook site (SWN9) and the sixteen SCWQIP sites

have not been presented yet as sampling only began in March 2010. Data is

presented in graphical and tabular form for ten key analytes; Total Nitrogen, Nitrogen

as ammonia/ammonium, Total Oxidised Nitrogen, Dissolved Organic Nitrogen, Total

Phosphorus, Soluble Reactive Phosphorus, Dissolved Organic Carbon, Total

Suspended Solids, Dissolved Oxygen and Specific Conductivity.

At each site the data is presented as a graph showing the background five years of

data as monthly box plots overlain by the current year monthly medians. Catchment

data is presented over a calendar year (January to December), with quarterly reports

corresponding to the quarters of the year (Jan-Mar, Apr-Jun, Jul-Sep, Oct-Dec) and

each quarterly report adding to the “current year” data already presented.

This data report is the second quarterly report for 2013 and presents 2013 data from

January to June over background data from 2008 to 2012. The background monthly

box plots display the median, 25th, 75th, 10th and 90th percentiles where sufficient data

exists. The graphical program used (Sigma Plot) requires a minimum of 3 data points

to calculate 25th and 75th percentiles and a minimum of 9 data points to calculate 10th

and 90th percentiles. Due to the ephemerality of many of the catchment sites and the

fortnightly sampling regime, the background monthly sample numbers may often be

quite low. For clarity the background monthly sample numbers (n=) have been

reported on each graph. All data recorded below the laboratory limit of reporting was

halved in order to be graphed.

The current year’s data (2013) is also presented in tables showing monthly minimum

and maximum values and the number of samples collected for each analyte.

Data, collected from the sixteen SWANCATCH and sixteen SCWQIP sites, is also

displayed in tabular form near the end of this report with quarterly means and

standard deviations of the ten key analytes displayed for all sites in one comparison

table for each quarter reported.

During the final quarter of 2013 Perth received only 50mm of rainfall, roughly half the

long term average (90mm). By the end of the year six of the 15 catchments had

ceased to flow which is unusual (especially given the higher than average rain

received during the third quarter of the year) and especially notable was that the

Avon, a supposedly permanent system, had ceased to flow by the final sampling

event of 2013 (31/12/2013).

Flow data is included for gauged catchments with a full year of data, of which there

are eight; although the Walyunga gauging station data (616011) is used for the upper

Swan river site (SWN5) so flow data for nine sites in total is provided. This year’s flow

data however doesn’t include the three Water Corporation gauged sites, for which

there is still no data.
