Is there a forum here to ask the DNR questions? How does the DNR determine if a specific lake they manage and stock is being overfished?  Just by the lack of creel report numbers, spring shocking programs, etc.,?  How do they estimate how many walleye are being harvested? Is that part of their shocking and tagging programs, reported tribal spearing reports and estimates of what should be left based on their projections and formulas for how many fingerlings they stock and how many of those should survive to maturity?  But how do they know how many fish 'anglers' are taking?  (I sure ain't one of them!  LOL!)  For instance, using Lake Namakagon, in Cable, Wisconsin, with known records of stocking, shocking, creel reports, tribal numbers, etc., how many anglers, would have to catch how many fish, from one year to another, to affect or calculate what the walleye population is to the degree it has been affected in this lake anyway?
