- We report on our effort from October 1990 through March 1991 to prepare for the evaluation of the juvenile fish bypass facility in the West Extension Irrigation District Canal at Three Mile Falls Dam on the Umatilla River. We also report on our preliminary activities to prepare for future evaluations at Maxwell and Westland diversion dams. A detailed sampling plan was written to guide our efforts in the evaluation process and associated preparatory activities were conducted. In the sampling plan, we developed experimental designs for evaluating the passage of juvenile salmonids through the bypass system including the evaluation at design flow of injury and mortality rates, and passage of juvenile salmonids through and over the screens. We designed and fabricated fish nets for screen leakage tests, and holding facilities for test fish. Modifications to improve evaluation activities were incorporated into the collection facility, and our sampling gear. We designed and fabricated collection systems for the juvenile fish bypass facilities at Maxwell and Westland diversion dams. Preliminary monitoring of system operation was performed at Westland Diversion Dam. We offer recommendations for improving preparations and designs of future evaluations, and also recommend that a detailed evaluation of the Maxwell and Westland juvenile facilities, including evaluation of fish condition and fish passage through or over the screens, be conducted.
