Don't say that pelican, you'll only feed his ego even more....LOL Just kidding. Nice Koke Carl, didn't know they were in Washington. I've never really fished for them untill 2 years ago in Montana. But we caught numerous Kokes over 4lbs. Yes, 4lbs. Longest one we got was 21 inches. Dats a big fish. So they are more than capable of getting alot bigger than 15" in such a lake as Washington. Did you happen to notice any schools around you on the fishfinder when you hooked it??? I wonder how thick they are...
