I thought it might be useful to summarize the DNR fishing limits. The DNR does frequent the lake and so you will want to ensure you understand the law.
If you are reading the Fishing Regulations Book, we fit into the North-central Zone. Basically, that is everything north of highway 7 and the Minnesota River which connects to the Mississippi in the Twin Cities.
Northern pike = limit 10, not more than 2 over 26", all from 22" to 26" must be immediately released.
Walleye = limit 6, not more than 1 over 20".
Musky = 1, minimum 54"
Largemouth bass = 6
Smallmouth bass = 6
Crappie = 10
Sunfish = 20
Something to consider, especially with Northern and Walleye, the larger fish are most typically female and would be considered brooders. Lake residents and the larger fishing community would consider proper etiquette to take a picture and immediately release the fish.
Also, fishing in deep water requires patience and skill to avoid killing a fish. The pressure difference between 40+ feet of water and the surface is great and a fish needs to make that transition slowly. It's not advisable to attempt to catch fish at that depth.
Lastly, if you are storing or transporting fish, you must do so in such a way that they can be readily unwrapped, separated, identified, and counted. Identification is done by leaving a 1" square of skin attached to each fillet. The exceptions are bullhead, sunfish, and crappie do not need the skin attached. While it's not common, the DNR has followed a few of our more experienced fishermen into their cabin to inspect the freezer, so it can happen.
