I need info on walleye spawning and structure. I have a one acre pond in Wisconsin, 4-1 pitch, 10-29 depth down the center, some ledges, numerous christmas trees sank, 7 loads of field stone on a 10 foot ledge. Am i going in the right direction to insure that my walleye will spawn? We stocked the pond 3 years ago, walleye were 6 inches at the time, caught some 12,13 inchers this winter. Fish seem healthy, how do I insure that they will reproduce?
