4,210-acre lake near T8 R14 WELS. The lake tops out around 89 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 4,202 acres, worked by 23.2 miles of shoreline, with 18 islands in the mix. That shoreline is heavily fingered (development index 2.6) — bays, points and pockets everywhere, which multiplies the fishable edge. About 23% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 4.7 mi end to end and 3.8 mi across at its widest. Piscataquis County claims this one. If the bite dies, Johnson Pond is 2 mi to the west.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Creek inflow: an inflow / creek mouth around 8 ft that scores prime in spring. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Creek inflow (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Creek inflow (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Creek inflow (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Creek inflow (8 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring burbot on Allagash Lake hold shallow, usually 25 to 70 ft. They move out to 27 to 89 ft in summer and finish the year down in 15 to 60 ft. Put Deep basin first on the milk run — a deep basin near 80 ft that grades prime for summer. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (80 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 27 to 89 ft | night & midday | Deep basin (80 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (80 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Rock reef (5 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Spring lake trout on Allagash Lake hold shallow, usually 10 to 40 ft. They move out to 27 to 89 ft in summer and finish the year down in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 80 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (23 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 27 to 89 ft | dawn | Deep basin (80 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Rock reef (5 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (80 ft) | White tube jig, Airplane jig |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 27 to 89 ft before dropping to 25 to 70 ft for winter. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 80 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Shallow feeding flat (20 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 27 to 89 ft | dawn | Deep basin (80 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (5 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Break off the point (58 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
