WDFW Help

There are some positive signs, but it is too soon to assess the success of the states' efforts. The good news is that the number of California sea lions feeding in the tailrace area has declined from a high of 104 animals in 2003 to 39 in 2012. The percentage of protected salmon and steelhead runs consumed by California sea lions has also declined in recent years, although that trend is partly due to larger salmon runs in recent years. Run timing and river conditions also affect predation rates, complicating an assessment of the states' efforts.
