Part of my curiosity stems from the diversity of the river habitat between, say, the Twin Cities and the Quad Cities (lotsa cities on ‘dem rivers).
Essentially, it goes from river, to lake Pepin, back to river, and into the endless backwaters of pools 8-10, then back to river, then no safe ice. I’d be willing to bet that nowhere in the upper midwest (possibly Devil’s lake, but population is so low up there?) that gets pounded pounded pounded like pools 9 and 10 during the winter. This is the first year where a limit would have any impact, yet the last few years fishing has been phenomenal. Older studies in the lower pools have shown that siltation is the largest detriment to the fishing, with anglers not even in the noise, but I haven’t seen anything newer than maybe 5 years.
Are the panfish population and sizes better on the lower pools, and if so, is it the fact that they don’t get safe ice, or just the generally warmer temps? There’s too many variables to attribute short-term trends to specific changes, but hopefully the new limits end up being a benefit to us all. For now, though, I would have a serious problem finding fault in someone who kept fish to eat given that’s what the DNR here has always told us to do.
