Water Temperature Mapping Snoqualmie and Skykomish River Basins

Water Temperature Mapping in the Snoqualmie and Skykomish River Basins - Preliminary Results - Dan Restivo Hydrologic Technician USGS Washington Water Science Center [email protected] Why study water temperature? It limits the distribution and health of fish and other aquatic life, affecting their physiology and behavior - Governs body temperature, reproduction, and metabolism of most aquatic organisms - Affects the timing of migration, spawning, and rearing. - Controls the amount of DO in the water. - Alters the resistance of fish to pollutants and disease - Thermal stresses on salmonids reduce their likelihood for long-term survival and can be lethal.

Identify areas of persistent thermal contrasts (warm or cold) for potential use in siting restoration projects. • e.g., large woody debris, riparian restoration, levee setbacks, habitat protection 2. Profile water temperatures upstream to downstream for potential use in watershed scale models. • e.g., Distributed Hydrology Soil Vegetation Model (DHSVM) 3. Compare three common methods of collecting spatially distributed water temperature • Helicopter-based thermal infrared (TIR) surveys • Drone-based TIR surveys • Drag-probe (kayak-based) surveys Helicopter-based Thermal Infrared Surveys – (August 2020 and 2021) Gold Bar Monroe Carnation Taylor River Snoqualmie North Bend Goldmyer Hot Tanner Springs Drone-based Thermal Infrared Surveys – (August 2020) Snoqualmie North Bend Tanner Drag-probe Water Temperature Survey (August 2020) Monroe Gold Bar Taylor River Snoqualmie North Bend Tanner August 16, 2020 10.0 Preliminary Results August 16, 2020 10.0 Preliminary Results August 16, 2020 10.0 Preliminary Results August 16, 2020 Preliminary Results August 16, 2020 Preliminary Results August 16, 2020 Preliminary Results Snoqualmie River Longitudinal Temperature Profile Raging River Griffin Creek Kimball Creek Snoqualmie Falls Tolt River Side Channel NF Snoqualmie Patterson Tokul Creek Side Channel Creek SF Snoqualmie Snoqualmie Falls Golf Course Unnamed tributary upstream of Tolt bridge Preliminary Results August 16, 2020 Preliminary Results Preliminary Results August 16, 2020 Preliminary Results August 16, 2020 10.0 Preliminary Results Preliminary Results Middle Fork Snoqualmie River Longitudinal Temperature Profile Taylor River Pratt River Granite Dingford Creek Creek Unnamed tributary Groundwater Inflow Preliminary Results Preliminary Results Preliminary Results Preliminary Results Preliminary Results Preliminary Results Preliminary Results Preliminary Results Preliminary Results Skykomish River Longitudinal Temperature Profile Trib/Side Channel Barr Creek McCoy Creek Elwell Creek Woods Creek Proctor Creek Trib/Side Channel Sultan River Preliminary Results Preliminary Results Preliminary Results Preliminary Results Preliminary Results Preliminary Results Questions?
