Snoqualmie habitat and watershed conditions

"2016 Snoqualmie River Water Temperature Study"
This report summarizes temperature work done on the Snoqualmie River during the summer of 2016. This study looks at how groundwater and hyporheic flow may be influcencing temperatures in the Fall City to Carnation reach of the Snoqualmie River.

"WRIA 7 Climate Change Impacts to Salmon Issue Paper"
This report summarizes current climate science and the ways it is expected to influence salmon and their habitat in the Snohomish Basin. The report sets forward key actions which are recommendations for restoration priorities that could build resilience for both salmon and the larger Snohomish Basin ecosystem.

"Hot Water and Low Flow: The Summer of 2015 in the Snoqualmie River Watershed"
This report summarizes water temperatures measured during the summer of 2015 in the Snoqualmie River watershed. Temperatures were considerably higher than normal and flows were at a record low across the watershed. This work emphasizes the value of addressing water temperature issues at a site- and basin-scale to build watershed resiliency for salmon.

South Fork Skykomish River Basin Restoration Feasibility Project – Restoration Opportunity Report: April 2013
This report identifies habitat restoration opportunities in the South Fork Skykomish River basin and its tributaries, located in eastern King and Snohomish Counties, Washington. The report builds on a three phase assessment including gathering existing natural resource information, conducting targeted assessments, and prioritizing restoration opportunities.

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.

Snoqualmie Watershed Geology Report: An Overview of the Geology and Geomorphology of the Snoqualmie River Watershed

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.
