24-acre lake near T4 R9 WELS. The lake tops out around 17 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 24 acres of water rimmed by 1.5 miles of bank. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. End to end it runs roughly 0.6 mi, about 0.2 mi across. The water lies in Piscataquis County. Closest neighbour on DepthScout: Six Ponds #3, 0 mi west of here.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 5 to 17 ft before dropping to 3 to 17 ft for winter. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 14 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.
