I just got back from Harvey Gap, going after perch and came home with not a fish. water temp was 48 in the AM and up to 51 in the PM. Fished the shorelines all the way out to the deeper parts. Did see quite a few large pike close to shore on what looked like their spawning beds. Went right over a few big ones with the boat and they just stayed put. Trolled for pike for an hour or two with nothing as well.
