1,053-acre reservoir near Musquash Parish. Government of New Brunswick lake depth survey. The lake tops out around 60 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. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 1,064 acres of water rimmed by 29.8 miles of bank, broken up by an island. That shoreline is heavily fingered (development index 6.5) — bays, points and pockets everywhere, which multiplies the fishable edge. 83% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 4 mi of water from one end to the other, 2.3 mi at the beam. You'll find it in Saint John County. Closest neighbour on DepthScout: Shadow Lake, 1 mi southeast of here.
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 20 to 45 ft for winter. Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 8 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.

Spring chain pickerel on East Branch Reservoir hold shallow, usually 2 to 10 ft. They move out to 3 to 15 ft in summer and finish the year down in 5 to 18 ft.

The summer box starts with a weedless spoon + trailer or a buzzbait.
