Dylan,
Here’s a link to the DNR Website:
Laker Finder
It’s an application they have called Lake Finder. You can read the reports they have on Minnesota lakes and also download maps. Maybe you could look up local area lakes and see what the DNR has to say about them.
The other thing you can do is hang around bait shops. Buy something…..and then start asking questions. You might get a few good ideas from that.
Good luck and let us know about your success!
