Uncle buck,
I believe there is some very sound science behind this study. As the water cools and the flow subsides, the saugers pile up in the 30+ foot deep holes, and the fishermen follow. Thousands of short saugers pulled from these deep holes die from bladder distension.
It would be great if anglers would take the initiative and just not fish those deeper holes, but that will never happen. I am sure that the sauger population on pool 14 has benefited from the closing here, and still plenty of fish can be caught downriver.
Ideally, educating anglers on the negative effects of fishing the deep water may lead to less restrictions, but with an ever increasing number of fishermen out there chasing saugers, the DNR is doing what it can to ensure a good fishery for our children.
I understand the frustration of not being able to fish the dam during the winter. I enjoyed it as well, not to kill a limit of fish each time out, but to catch a few eaters and enjoy time on the water with fellow outdoorsmen. Unfortunately there are just too many who hammer these fish unmercifully while they are at their most susceptible. The days of full stringers and filling the freezer need to come to an end to maintain our great river fishery. I would not look for the dam closing to end any time soon.
