Hood River and Pelton Ladder Evaluation Studies, 2008 Annual Report : October 2007 - September 2008.
- Oregon Department of Fish and Wildlife
This report summarizes the life history and production data collected in the Hood River subbasin during FY 2008. Included is a summary of jack and adult life history data collected at the Powerdale Dam trap on seventeen complete run years of winter steelhead, spring and fall chinook salmon, and coho salmon, and on fifteen complete run years of summer steelhead. Also included are summaries of (1) the hatchery winter steelhead broodstock collection program; (2) hatchery production releases in the Hood River subbasin; (3) subbasin wild summer and winter steelhead smolt production, (4) numbers of hatchery summer and winter steelhead smolts leaving the subbasin; (5) smolt migration timing past Bonneville Dam, (6) wild and hatchery steelhead smolt-to-adult survival rates; (7) wild summer and winter steelhead egg to smolt survival rates; and (8) streamflow at selected locations in the Hood River subbasin. Data will be used in part to (1) evaluate the HRPP relative to its impact on indigenous populations of resident and anadromous salmonids (see Ardren Draft), (2) evaluate the HRPP's progress towards achieving the biological fish objectives defined in the Hood River Subbasin Plan (Coccoli 2004) and the Revised Master Plan for the Hood River Production Program (HDR|FishPro, ODFW, and CTWSRO 2008), (3) refine spawner escapement objectives to more accurately reflect subbasin carrying capacity, and (4) refine estimates of subbasin smolt production capacity to more accurately reflect current and potential subbasin carrying capacity.
