32-acre lake near Alder Brook Twp. The lake tops out around 8 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 31 acres of water rimmed by 1.4 miles of bank. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 0.6 mi, about 0.2 mi across. You'll find it in Somerset County. The nearest mapped water is Ironbound Pond, 2 mi to the southeast.
Spring puts brook trout in skinny water — 1 to 8 ft is the zone. Summer fish stay in 2 to 8 ft, and winter fish hold in 1 to 8 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 8 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |

| Spring | 1 to 8 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
