Canyon Release and Flow Notices

Flow releases at Canyon Reservoir will be temporarily suspended at 6 p.m. Thursday, July 21, 2016, to allow work crews to make required repairs. It is anticipated that repairs will require flows to be suspended for no more than two hours, at which time flow releases will recommence at 300 cubic feet per second (cfs). Effects of suspended flows should be minor on the segment of the river closest to Canyon Dam. It should not affect the hydroelectric lakes downstream.
