I icefish a manmade impoundment for trout in connecticut. I've caught brown trout to 7lbs., rainbows to 5lbs, and brookies to 3lbs. However, the action is rarely hot, and I just cannot seem to pinpoint the movements and activities of the fish. The lake is several hundred acres, depth to 90ft.+, water very clear, practically devoid of weed growth, generally soft bottom and sand, gravel, some rock outcrops, several good feeder streams. Cannot connect with anything jigging. Have caught perch to 2lbs. on tipups, hard to locate jiggables. According to stomach contents of the trout, perch appear to be the only fin food, yet also an abundant amount aquatic insects are ingested. I generally fish minnows on the tips, but have scored with worms. Jiggin' produces notta. Looking for some tips to better locate the 10lb+ brown trout I'm looking for.
