223-acre lake near T1 R10 WELS. The lake tops out around 150 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.
Traced from the shoreline, Fourth Debsconeag Lake runs 223 acres with 3.2 miles of edge. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 10% of the surface — that's where the groceries are. The basin spans about 1.2 mi end to end and 0.5 mi across at its widest. The water lies in Piscataquis County. For a second option, Second Debsconeag Lake lies 3 mi northeast.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Break off the point, a drop-off in about 28 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (28 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Back-bay flat (4 ft) | Small jigging spoon, Tungsten jig + plastic |
Fourth Debsconeag Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 150 ft down.
