12-acre lake near Prentiss Twp T4 R4 NBKP. 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. What the data behind the map says about each species, season by season:
Traced from the shoreline, Lower Welman Pond runs 12 acres with 0.6 miles of edge. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Call it 0.3 mi long. The water lies in Somerset County. Closest neighbour on DepthScout: Upper Wellman Pond, 0 mi north of here.
In spring, brook trout run shallow here, mostly 1 to 8 ft. Summer keeps them at 2 to 8 ft, and they winter in 1 to 8 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 8 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 8 ft | dawn & dusk | Deep basin (8 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 8 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 8 ft | dawn | Deep basin (8 ft) | Small jigging spoon, Tungsten jig + plastic |
