The only real problem that I see is that by opening a targeted season on spring chinook jacks, it creates that grey area for unscrupulous anglers to target the depressed adult run, using the excuse "hey, we were fishing for jacks." It seems that by trucking them over the dams, (which I don't believe they do with springer adults?) and only targeting them in the lakes, it removes the possibility of the mobs coming down to the Cowlitz for the jacks, and hooking and keeping springer adults. Maybe if they had an incidental catch rule or something along those lines, especially for the fall Coho jacks, a resolution to this problem could be reached.
