Re: Health concerns & warmwater fish
Most serious fishermen C&R on the Willamette. I wouldn't eat anything that wasn't anadromous out of that water. 50% of the fish in the lower river have skeletal deformities as a result of the pollution. I know that many (not to be discriminatory) immigrants do catch and eat a lot of the trashier fish out of the river (ie carp, crappie, bullhead, suckers). I don't think most of them realize the dangers of eating these fish. Oregonian did a good article on the pollution and the fish in the lower Willamette a few months ago. Reinforced my decision not to eat anything out of there.
As far as the Columbia goes, around Camas would be BETTER than below Kelly Pt, but I don't really think those fish taste good enough to mess w/ eating them. You can catch some great walleye and bass in that area if you know where to fish. I just don't think that they taste good enough to counter the serious HEALTH RISKS. If you want to eat some of your bass or walleye, you might want to consider traveling. The walleye around the Dalles Dam would probably be okay to eat, but throw the big ones back. They don't taste as great and they can only get biggger! Best eating smallmouths will come out of the John Day or the Umpqua if you are willing to make the trek. Plenty of good farm ponds and lakes in the area that hold big largemouth bass. Can anyone say Hagg Lake or Smith and Bybee? I'm sure some of them might even be okay to eat out of. I just make it a point not to eat any of the bass or panfish I catch from the Willamette drainage. Too much bad s***t in the water. Good luck.
Is this your homework Larry?
