This report summarizes and interprets data collected in the field from 1999-2001 about habitat conditions for multiple species of salmonids and other aquatic biota in aquatic ecosystems of the Snoqualmie Watershed, including the mainstem Snoqualmie River and several of its tributaries. Previously existing information about habitat conditions for fish and other aquatic biota in the Snoqualmie Watershed is also summarized in the report.

Information from this report will be used as part of a larger effort to assess what is currently known and what additional information is needed about the Snoqualmie Watershed in order for King County to proceed with long-term salmon conservation and recovery in the watershed and in WRIA 7 overall. The report is the first step in framing the questions that need to be answered in the Snoqualmie Watershed portion of the WRIA 7 strategic assessment/ecological analysis and in building the Snoqualmie Aquatic Resources Assessment, which is a comprehensive technical study program for the Snoqualmie Watershed.
