I have a 1 acre pond (about 20 ft deep) in the St. Louis area. I was thinking about adding yellow perch and/or walleye. The pond is currently stocked with BG, RES, CC and LMB. None of the lakes around here have YP, so I was wondering if I was just too far south? We loved catching Yellow Perch and Walleye when we lived up north. Any thoughts?
