Sauvie Island, Multnomah Channel, Vancouver Lake, Lake River: yes, the disgusting widening/confluence of multiple rivers, with a bunch of Islands and swampy ponds that are infested with carp-chumming is legal. But only on the Washington side, and only in the general area described above. I can say for sure Vancouver Lake, Lake River, Canvasback Lake, Quigley Lake, Campbell Lake, Post Office Lake, Green Lake, Round Lake, Curtis Lake, and like 5 other unnamed lakes all have allowed chumming. But Oregon has absolutely no chumming.
