Sure everyone know sockeye! At least in one form...kokanee! But sockeye do travel the Columbia but no they don't show in the columbia in good numbers from a catch basis(I don't believe retention is legal but...gill nets)and they're often bound for out of state waters while there. Now that they've opened Billy Chinook to fish passage fish biologists are hoping for a that some of the 300,000 juveniles that followed their instinct to migrate to the ocean will make it back and establish a reproducing population there and in the Metolius(which the kokanee already go up to spawn). Sockeye aside from being the second smallest pacific salmonoid(pinks being the smallest, adult sockeye average 6-10lbs) are unique in that they require lakes for spawning grounds so they only (intentionally)appear in rivers that drain said bodies of water. The YTD count over Bonneville is currently just under 51,000 sockeye compared to 381,000 chinook
