"Those areas for the most part don't exist on the Columbia anymore"

They do at the dams, just sort the fish as they are counted, give everyone thier allocation by zero by catch. Do it low enough (Bonni) in the system and the fish will be brighter, less stressed, and have a higher fat content. The corps could even save some money by pulling out some Squawfish.

If people really wanted to work on maximizing the returns only bucks could be selected to allow a higher return of hens. I theory more wild fish smolting after time we may have something.
