6,088-acre lake near Bridgenorth. The lake tops out around 22 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 6,157 acres of water rimmed by 52.9 miles of bank — 3 islands included. That shoreline is heavily fingered (development index 4.8) — bays, points and pockets everywhere, which multiplies the fishable edge. About 95% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 13.8 mi with a 2.6-mi widest point. The water lies in Peterborough County. Closest neighbour on DepthScout: Chemong Lake, 2 mi south of here.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 7 to 22 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
