Hoh Tribe FY23 Forward Looking Infrared Flight

FLIR has been demonstrated as a reliable, cost-effective, and accessible technology for monitoring and evaluating stream temperatures from the scale of watersheds to individual habitats. Stream temperatures in the Hoh River and South Fork (SF) Hoh River (on the West slope of the Olympic Peninsula, WA) were last mapped in the year 2000. With this funding, the tribe will obtain updated FLIR information. This funding will contribute to approximately half of the Wild Salmon Centers cost to fly the FLIR flight in the Hoh River Subbasin.

FLIR will enable the Hoh Tribe to evaluate current climate change impacts and to better identify project areas to target for restoration. The Hoh Watershed encompasses an area of approximately 167,000 acres and includes the Hoh River, South Fork of the Hoh Rives, and approximately 28 tributaries. FLIR flights are typically completed during low flow conditions, approximately August-September.
