In lower michigan we have 3 weeks of spearing left. With prespawn habits comming, where should I move the shanty to ? I'm thinking in shallow in front of the one swamp on the south east side of the lake. The very weedy lake is 22 acres with a bowl shaped mucky bottom. max depth 30 feet. normally we spear the east side in about 8-11 feet of water, where the weeds drop off, but not necessarly the bottom. should we go shallower near the swamp as season nears end?suggestions/comments?
