Perch are easy peasy, on that lake. Might make for some fun, for the kiddo. Just toss out a bobber, and and a worm, near / into the grasses around Butterfly Island.
Another idea would be, to troll (flat line) a flasher/worm set-up in front of the Siltcoos River outlet. The SRC's should be trickling in. And the state record, is from that lake!
