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)
