Title: Hood River and Pelton Ladder Evaluation Studies, 1998-1999 Annual Report.

Technical Report ·
DOI:https://doi.org/10.2172/773020· OSTI ID:773020

This report summarizes the life history and production data collected in the Hood River subbasin during FY 1998 and 1999. Included is a summary of jack and adult life history data collected at the Powerdale Dam trap on eight complete run years of winter steelhead, spring and fall chinook salmon, and coho salmon, and on seven 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) the number of outmigrant wild rainbow-steelhead and hatchery summer and winter steelhead smolts; and (4) streamflow at selected locations in the Hood River subbasin. Data will be used in part to (1) evaluate the HRPP with respect to its impact on indigenous populations of resident and anadromous salmonids, (2) refine spawner escapement objectives to more accurately reflect subbasin carrying capacity, and (3) refine estimates of subbasin smolt production capacity to more accurately reflect current and potential subbasin carrying capacity. Baseline information on indigenous populations of resident and anadromous salmonids will continue to be collected for several years prior to full implementation of the Hood River Production Program.
