43-acre lake near Prentiss Twp T4 R4 NBKP. The lake tops out around 24 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
Upper Wellman Pond maps at 43 acres behind 1.2 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. About 86% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.4 mi with a 0.3-mi widest point. Somerset County claims this one. Lower Welman Pond sits 0 mi south — the closest neighbouring chart.
Spring brook trout on Upper Wellman Pond hold shallow, usually 2 to 15 ft. They move out to 7 to 24 ft in summer and finish the year down in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 24 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
