The Washington Department of Fish and Wildlife (WDFW) has been monitoring Touchet River summer steelhead (Mid-Columbia River Distinct Population Segment) smolt production as one of the Fish In/Fish Out (FIFO) projects across the State. The smolt trap is located immediately below where the Harvey-Shaw road crosses the Touchet River (~RM 30 - T9N R35E Sec 6). The trap has purposely been located below the Major Spawning Area (MSA) of the Touchet River, and based on previous WDFW spawning and juvenile surveys, is well below all known spawning/juvenile rearing areas for Touchet River summer steelhead. The smolt trap is operated continuously from October to June each year (except during inoperable river conditions such as high stream flows or ice conditions). The main monitoring objectives have been to estimate/understand smolt yield and life history diversity, in addition to tagging all juvenile migrants with Passive Integrated Tags (PIT) to monitor the juvenile outmigration, estimate smolt-to-adult survival (SAR) and adult abundance, many of which are critical Viable Salmonid Population (VSP) parameters. 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 Major Population Group. Population monitoring (juvenile and adult) is a foundational component of science-based recovery actions a
