1,219-acre lake near T4 R11 WELS. The lake tops out around 134 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 1,217 acres of water rimmed by 10.1 miles of bank, with 6 islands in the mix. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. 32% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 3.6 mi of water from one end to the other, 0.9 mi at the beam. The water lies in Piscataquis County. For a second option, Duck Pond lies 2 mi west.
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 50 to 120 ft, wintering in 20 to 80 ft. Spring lake trout concentrate at Main-lake point, a prime-rated point around 19 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (130 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (19 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (29 ft) | White tube jig, Airplane jig |
Spring puts landlocked salmon in skinny water — 1 to 15 ft is the zone. Warm water sends them out to 25 to 60 ft; cold water stacks them in 10 to 40 ft. Smith Brook inflow is the standout, an inflow / creek mouth at roughly 3 ft, rated prime for spring landlocked salmon. Plan around early morning and the evening in the warm months. A dodger + streamer down deep or a thin spoon on lead core covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & dusk | Smith Brook inflow (3 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (29 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | Soper 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 |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 10 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring brown bullhead. Time it for after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (2 ft) | |
| Summer | 3 to 12 ft | night & dusk | Back-bay flat (4 ft) | |
| Fall | 5 to 15 ft | dusk | Back-bay flat (4 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (130 ft) |
Spring puts burbot in skinny water — 25 to 70 ft is the zone. As the season builds they drop to 50 to 120 ft, wintering in 15 to 60 ft. Summer burbot concentrate at Deep basin, a prime-rated deep basin around 130 ft. Warm-month bites cluster around after dark and midday. A heavy jig + cut bait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (29 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Deep basin (130 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (29 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (29 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
