The Okanogan River (WRIA 48) system is currently listed as a 303(d) stream due to water temperature exceedances. The Okanogan is inhabited by steelhead (ESA Endangered), bull trout (ESA Threatened), sockeye, and summer/fall chinook. Spring Chinook and Coho are considered to be extirpated from the basin.
The Limiting Factors Analysis (SRFB) and the Okanogan Subbasin Summary (NWPPC) both list water temperatures as a factor limiting salmonid production. Determination of thermal input sources is a necessary precursor to corrective action.
This project will employ Forward Looking Infra-Red (FLIR) thermal imaging technology to collect water temperature information which, along with densiometry, riparian vegetation, stream flow, climate, and stream channel width-to-depth ratio data, will be incorporated into a Stream Segment Temperature Model (SSTEMP) to assess thermal input sources and potential corrective measures.
This project will include in-kind cost sharing and participation with a coordinated group of state, federal, and tribal entities.
