2,605-acre lake near T2 R13 WELS. The lake tops out around 54 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 2,606 acres of water rimmed by 35.5 miles of bank, with 56 islands in the mix. With a shoreline index of 5, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 44% of the surface — that's where the groceries are. The basin spans about 6.3 mi end to end and 2.2 mi across at its widest. The water lies in Piscataquis County. Closest neighbour on DepthScout: Berry Pond, 2 mi southwest of here.
In spring, landlocked salmon run shallow here, mostly 1 to 15 ft. Midsummer fish sit out in 16 to 54 ft before dropping to 10 to 40 ft for winter. Spring landlocked salmon concentrate at Bear Brook inflow, a prime-rated inflow / creek mouth around 5 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + streamer down deep or a thin spoon on lead core most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & dusk | Bear Brook inflow (5 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 16 to 54 ft | dawn & dusk | Deep basin (50 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | Bear Brook inflow (5 ft) | Casting spoon at the mouths, Streamers |
| Winter | 10 to 40 ft | dawn | Break off the point (29 ft) | Small jigging spoon, Swedish pimple + smelt |
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Bear Brook inflow is the standout, an inflow / creek mouth at roughly 5 ft, rated prime for spring brook trout. Plan around early morning and the evening in the warm months. 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 | 2 to 15 ft | dawn & dusk | Bear Brook inflow (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Creek inflow (7 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Bear Brook inflow (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Bear Brook inflow (5 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 3 to 12 ft, wintering in 10 to 25 ft. Summer brown bullhead concentrate at Shallow bay flat, a prime-rated weed flat around 12 ft. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Bear Brook inflow (5 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (12 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (12 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (50 ft) |
In spring, burbot run shallow here, mostly 16 to 54 ft. Summer keeps them at 16 to 54 ft, and they winter in 14 to 54 ft. Deep basin is the standout, a deep basin at roughly 50 ft, rated prime for spring burbot. Time it for after dark and midday. You won't need more than a heavy jig + cut bait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 16 to 54 ft | night & dusk | Deep basin (50 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 16 to 54 ft | night & midday | Deep basin (50 ft) | Heavy jig + cut bait |
| Fall | 16 to 54 ft | night & dusk | Deep basin (50 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 14 to 54 ft | night & dusk | Deep basin (50 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 16 to 54 ft, and winter fish settle into 14 to 54 ft. Deep basin is the standout, a deep basin at roughly 50 ft, rated prime for summer lake trout. Time it for early morning. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (13 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 16 to 54 ft | dawn | Deep basin (50 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (13 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 14 to 54 ft | dawn | Deep basin (50 ft) | White tube jig, Airplane jig |
