Green Peter reservoir.

Deep drawdowns planned at two Willamette Valley Project reservoirs are bringing a greater sense of urgency from Bonneville Power Administration and the Public Power Council for completing studies needed to deauthorize the system's hydroelectric projects.

The U.S. Army Corps of Engineers announced earlier this month it will begin gradual drawdowns at reservoirs behind Lookout Point and Green Peter dams in June, and bring them to historically low levels to aid juvenile fish passage.
