Federal agencies Friday delivered a mixed report card on their efforts to recover endangered salmon in the Columbia River.
The report was delivered to federal judge Michael Simon in Portland. He is overseeing the legal case involving salmon and dams along the Columbia. The Bonneville Power Administration says this year's report shows some improvement in returning adult salmon and steelhead numbers. In 2011, the number of adult salmon migrating past the Bonneville Dam was the fourth highest since 1938.
Part of that improvement was due to more spill as ordered by Judge James Redden who stepped away from the case last year.
The report also indicates that more work needs to be done to address predators. Birds, sea lions and pikeminnow remain problems for salmon.
