10-acre lake near Prentiss Twp T4 R4 NBKP. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Drawn out, this is 10 acres of water rimmed by 0.6 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 96% of this chart. The water lies in Somerset County. Closest neighbour on DepthScout: Hall Pond, 0 mi southwest of here.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 18 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
