Restoring Fish Runs Above PGE's Deschutes River Dams

For the first time in 40 years, salmon and steelhead could soon be
swimming their way down the Metolius, Crooked and upper Deschutes
Rivers as a result of new equipment now in advanced stages of
construction.

Fish passage around the Pelton and Round Butte dams on the Deschutes
River will be achieved through
a 273-foot underwater tower
and fish collection station.

The sorted fish will have to be trucked around the dam to continue their journey to the Columbia and trucked back around when they return to spawn.
