The Washington Department of Fish and Wildlife conducted a monitoring project on the Touchet River, Wa. WDFW has been monitoring Touchet River summer steelhead (Mid-Columbia River DPS) smolt production as one of the Fish In/Fish Out smolt trapping projects across the State. The smolt trap is located immediately below where the Harvey-Shaw road crosses the Touchet River. Monitoring objectives have been to estimate smolt yield and life history diversity, in addition to PIT tagging all juvenile migrants to monitor their outmigration, estimate smolt-to-adult survival (SAR) and adult abundance, many of which are critical Viable Salmonid Population (VSP) parameters. The smolt trap is operated continuously from October thru June each year. Delisting of Mid-C summer steelhead has been discussed for years, but the lack high quality VSP information has limited the ability of the Federal Agencies to change the current status of the Umatilla/Walla Walla MPG. Population monitoring (juvenile and adult) is a foundational component of science-based recovery actions and tracking progress towards recovery. Therefore, operation of the Touchet River smolt trap and the resulting estimates (juvenile and adult abundance, productivity) play a critical role in this evaluation. This proposed monitoring project addresses a funding gap to normal trap operations due to cuts from other funding sources which had supported the project but are no longer able to.
