Description

Abstract: This report summarizes Umatilla River steelhead monitoring and Three Mile Falls Dam (TMFD) PIT tag detection system operations for calendar year 2017. This report also includes updates to long-term status and trend data for the ESA-listed Umatilla steelhead population, which is a large population within the Umatilla/Walla Walla Major Population Group. The project used two fixed site traps, PIT tags, and mark-recapture to assess the status and trend of juvenile abundance and productivity, estimate survival rates, and monitor life history characteristics. In addition, spatial distribution and density of summer steelhead redds were determined using a spatially balanced random sample (Generalized Random Tessellation Stratified) within a temporally based panel design. ODFW, East Region Fish Research (ERFR).

Purpose: The goal of the project was to provide status and trend data for summer steelhead in the Umatilla River to facilitate assessment of the Umatilla Basin Fisheries Restoration Program and to support Fish and Wildlife Program RM&E strategies. Specific Fish and Wildlife Program RM&E strategies include: 1. Assess the status and trend of juvenile abundance and productivity of natural origin fish populations. 2. Assess the status and trend of spatial distribution of fish populations. 3. Assess the status and trend of diversity of natural and hatchery origin fish populations.
