Rating depth structure for lake trout.

1,219-acre lake near T4 R11 WELS. The lake tops out around 134 ft. The depth chart comes from Maine Department of Environmental Protection 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.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

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 | open water |
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 good-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 |
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Spring brook trout concentrate at Smith Brook inflow, a prime-rated inflow / creek mouth around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Smith Brook inflow (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Smith Brook inflow (3 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Smith Brook inflow (3 ft) | Small jigging spoon, Tungsten jig + plastic |
