The Bonneville Power Administration this week agreed to begin a limited
summer spill program at two lower Columbia River dams to help juvenile
salmon remaining in the river pass federal projects.
At the multi-agency Implementation Team meeting this week, BPA said it
can spill 30 percent of the river at The Dalles Dam for up to two weeks
and about 45,000 cubic feet per second for 5 hours per day at Bonneville
Dam, depending on actual river flow.
