Service Description: Columbia River cold water refuges (CWR) are tributary rivers that are at least 2°C colder than the main Columbia River temperature. The Environmental Protection Agency (EPA) identified 23 tributaries that provide CWR, 12 of these are identified as “primary” CWR tributaries, comprising 98% of the total volume of available refuge, because of their size, accessibility, and documented or presumed use by migrating salmon and steelhead. Adult salmon and steelhead temporarily use CWR to escape warm summer river temperatures and help them successfully migrate up the Columbia River to their spawning grounds. Protecting and restoring these CWR is important for the survival of migrating salmon and the recovery of salmon populations.
The Columbia River Cold Water Refuges Plan is a scientific document with recommendations to protect and restore cold water refuges that focuses on the lower 325 miles of the Columbia River from the Snake River to the ocean.
Spatial data provided on February 21 and 23, 2024 in two zipped files via email to Tatiana Dreisbach at WSDOT tatiana.dreisbach@wsdot.wa.gov, from Peter Leinenbach at EPA Leinenbach.Peter@epa.gov. The original EPA data dated XX, X 2017, included four shapefiles: 1) upstream riverine boundary, 2) riverine banks 3) downstream riverine boundary, 4) three non-riverine CWR areas (Little White Salmon, Herman Creek, and Wind River). WSDOT digitized the EPA provided lines and points into polygons. These WSDOT adapted features are what is used in the WSDOT Stormwater Retrofit Prioritization Web Map. Where original EPA provided features of points and lines do not align, the WSDOT created data layer used the outer, more conservative feature location to create the WSDOT polygon features so that the WSDOT crated polygons represent the larger possible area of the original EPA data rather than a smaller possible area
