I have done very little with the MN DNR website, so not much of a comment on that end of it. WI has a ton of information, but often you need to dig for it. They did some changes on the website, and now not all the information that had been readily available populates. A lot of the comprehensive information on fyke netting, shocking data, creel census,…is found by doing seperate searches for that particular body of water.
As mentioned, if you contact a regional fisheries biologist, they’ll send you a lot of information if requested.
