When gates to irrigation ditches are closed, fish are stranded. Pictured here, Chauncey Goodrich uses an electrofishing probe while T.U. members and volunteers follow behind, ready to catch temporarily stunned fish tumbling in the flow. A young volunteer stands by on shore, ready to exchange an empty bucket for a bucket of captured fish. Captured fish are measured and recorded, then returned to the main river where the irrigation water came. 2008 file photo by Hal Erickson.
