My co-workers husband was on the big lake last weekend fishing walleyes with his 4 daughters. He caught the fish of a lifetime that day. It was a 44 lb. 7 oz. 53″ muskie. He caught it on 6 lb. test line rigging for walleyes. It took him an hour to land. The fish broke his landing net at one point. He and his youngest daughter had to scoop the fish up in their arms and lift it in the boat. Talk about a monster.
As DeeZee has pointed out there are some big northerns out in the basin and there are some big muskies there too. (Last summer I had a monster try to take a 3 lb. walleye at the boat off a mud flat.) So if your out trolling cranks, don’t be surprised if you catch something a little bigger than you expected.
Good luck!
