I have tried leeches on L. Erie with little succuess. However when I lived in MN I used leeches or black worms on Mil Lac lake. We used slip bobbers. That combination worked well. However you have to be anchored to slip bobber.

I have had tremedous success trolling for Walleyes. Using worm harness and gold or lemmon/lime spinners. I have been fishing between the South east corner of PIB and the North West corner of Kelly's. Avg fish size has been 3-lbs plus.

Good luck,
