Snoqualmie habitat and watershed conditions
Snoqualmie Watershed Water Quality Synthesis Report - January 2009
This report synthesizes information about water quality in the Snoqualmie River Watershed, located in eastern King County, Washington. The report brings together available water quality information in each of the key tributaries and mainstem areas to help identify priorities for on-the-ground actions.
Snoqualmie Watershed Aquatic Habitat Conditions Report: Summary of 1999 - 2001 Conditions
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.
Historic Habitat Conditions in the Snoqualmie River Valley [Collins and Sheikh, 2002] Archival materials, including maps and field notes from the General Land Office from 1871-1873 and aerial photographs from 1936, were entered into a geographic information system. In combination with a digital elevation model, these materials were used to map the channel, wetland, forest, and oxbow ponds in the Snoqualmie River valley prior to Euro-American settlement, or about 1870. To evaluate subsequent change, conditions were also mapped from 1936 and 2000 aerial photos.
