The DNR is using a 5 year plan and originally they had no intension of changing the regulation in that time, thinking it will balance out over the years but a few things have happened.
One, they found out that hardly any fish die of hooking mortality so those mortality rates they had been using are falsely high.
Second, they realize with the numbers of big fish in the lake they are not harvesting enough pounds of fish and it will be almost impossible to reach they safe harvest level unless they open it up to a year class that actually exists in the lake (little sarcasm there!!)
With that said, there is a good class of 19 inch fish. If they some how allowed the harvest of some of these they could catch up fast. I still think a limit of 4 fish with one over 19 like LOW has can work.
We did get a 9 inch, and two 11 inch walleye this year so there are a few little guys in there. But, the lake is dominated by big fish right now, no secret there. My only fear is when all these big fish get to that ripe old age, who will replace them. I am not sure the lake is “balanced” to well yet.
