Title: A Fisheries Evaluation of the Westside Ditch and Wapato Canal Fish Screening Facilities, Spring 1989 : Annual Report.

Abstract

We evaluated the effectiveness of new fish screening facilities in the Westside Ditch and Wapato Canal in south-central Washington State. The screen integrity tests indicated that test fish released in front of the screens could enter the canal behind the screens. At Westside Ditch, between 6% and 25% of the zero-age fry passed through the rotary drum screens. The 6% estimate is based on tests with rainbow trout Oncorhynchus mykiss fry. The 25% estimate is based on monitoring chinook salmon 0. tshawytscha fry that were diverted from the river into the irrigation ditch. At Westside Ditch, we estimated that 1.8% of steelhead 0. mykiss smolts and 0.3% of chinook salmon smolts released during tests were descaled. The time required for 50% of the test fish to exit from the Westside Ditch Screen forebay was 3 to 8 h for chinook salmon smolts and up to 28 h for steelhead smolts. Methods used in 1988 were first used at Sunnyside in 1985 and were used in subsequent years at Richland. Toppenish/Satus. Wapato. and Toppenish Creek. The methods and 1985 through 1987 results have been reviewed by the Washington State Department of Fisheries, U.S. Fish and Wildlife Service, National Marine Fisheries Service,more » Northwest Power Planning Council, and the Yakima Indian Nation.« less
