Another Predator Pike Discovered in Lake Davis

PORTOLA, Calif. — Another newly spawned northern pike was found in Lake Davis, bringing the total to five and raising concerns that the fish may have become established in the mountain lake, which state authorities poisoned in 1997 to eradicate the nonnative predator.

State officials treated the lake with poison in October 1997 to try to kill the pike and protect California salmon and trout downstream. The poison killed the pike--and other fish in the lake--and angered local residents, who complained that the state damaged their tourist-based economy and left the water tainted.
