Results from recent studies in Bear Creek will also be used to infer emigration timing, fecundity, and survivalratios of chinook fry in Little Bear Creek (Seiler, 2001). The validity of inferring similar trends is based onproximity, genetics, and stream temperature.

INSTREAM HABITAT DATA

Existing instream habitat data is available, but not fully compatible with current City of Woodinville goals.King County accomplished the most recent instream habitat survey conducted in Little Bear Creek during1999. The final draft report will be available by mid-April. King County surveyed most, but not all of LittleBear Creek within the City of Woodinville. The protocol used was a hybrid of the Timber-Fish-Wildlife(TFW) and May (1996) methodologies. Although this hybrid protocol was suitable in addressing KingCounty's needs, it is not comparable with on-going efforts in the upper watershed being conducted bySnohomish County or the draft protocol for WRIA 8. The results of recent macroinvertebrate studies willalso be incorporated into the final report (Morley, 2000).

Additional outdated data is also available in Reconnaissance Report No. 17 — Little Bear Creek (King County,1987). This report is very subjective, and does not provide references for the information contained within.Of particular interest will be checking if potential fish blockage and erosion concerns highlighted in 1987have been addressed.

The upper watershed in Snohomish County has not been surveyed. However, sections of Little Bear Creek inSnohomish County will be surveyed by Snohomish County (Purser, personal communication, 2001). Thisdata will hopefully be available for incorporation into the City of Woodinville Little Bear Creek HabitatCorridor study.

WATER QUALITY AND QUANTITY DATA

Water quality and quantity data is available for Little Bear Creek. King County has collected water qualityand quantity data in Woodinville for several years (King County, 1994). This data will be consolidated andanalyzed in the final report. Water quality data for the upper watershed within Snohomish County is alsoavailable and will be consolidated and analyzed in the final report (Snohomish County, 2000). Both countieshave provided recent unpublished water quality data to DEA for inclusion into the final report. DEA stillproposes to monitor temperature at the upstream and downstream city boundary to determine if temperature isa limiting factor and if temperature increases within the lower section of Little Bear Creek. This data willallow city planners and policy makers to determine if current land use activities and riparian coverage withinthe City of Woodinville are influencing stream temperature.

WILDLIFE DATA

Limited recent site-specific wildlife data is available for lands within the City of Woodinville. Four primarysources of existing literature to be utilized include the Priority Habitat and Species data (WDFW, 2001),Washington State Gap Analysis (Cassidy et al., 1997), Birding in Seattle and King County (Hunn, 1982), andKing County Wetland-Breeding Amphibian Monitoring Program (Richter et. al., 1999). Additional data has
