How many California sea lions have been removed from the lower Columbia River under federal authorization?

From 2008-10, wildlife managers for WDFW and ODFW removed a total of 40 California sea lions that met the federal criteria for removal below the dam. Of that number, 10 were placed in zoos and aquariums, which has been the states’ first choice whenever an accredited facility can be found to take them. Twenty-five others were euthanized by lethal injection and five died in captivity.

The states’ efforts to remove predatory sea lions were interrupted by a legal challenge in 2011, but resumed in April 2012 with federal approval. They are scheduled to continue through May, when most California sea lions leave the Columbia River and return to their breeding areas off Baja California.
