25,183-acre lake near T4 R12 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.
The chart traces 86.8 miles of shoreline here, broken up by 9 islands. The 4.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. 18% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 20.7 mi of water from one end to the other, 5.6 mi at the beam. You'll find it in Piscataquis County. Closest neighbour on DepthScout: Duck Pond, 7 mi southeast of here.
The spring pattern is a shallow one: burbot in 25 to 70 ft. Midsummer fish sit out in 50 to 120 ft before dropping to 15 to 60 ft for winter. The spot to know is Deep basin, a deep basin in about 108 ft of water that rates prime for burbot in summer. Plan around after dark and midday in the warm months. Summer baits: a heavy jig + cut bait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Offshore hump (15 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Deep basin (108 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Offshore hump (15 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Offshore hump (15 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Start shallow in spring: landlocked salmon sit in 1 to 15 ft that time of year. Summer pushes them deeper, 25 to 60 ft, and winter fish settle into 10 to 40 ft. The spot to know is Creek inflow, an inflow / creek mouth in about 12 ft of water that rates prime for landlocked salmon in spring. Warm-month bites cluster around early morning and the evening. Throw a dodger + streamer down deep or a thin spoon on lead core until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & dusk | Creek inflow (12 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 25 to 60 ft | dawn & dusk | Secondary point (28 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | Mud Brook inflow (17 ft) | Casting spoon at the mouths, Streamers |
| Winter | 10 to 40 ft | dawn | Main-lake point (13 ft) | Small jigging spoon, Swedish pimple + smelt |
The spring pattern is a shallow one: white perch in 4 to 15 ft. As the season builds they drop to 15 to 40 ft, wintering in 20 to 50 ft. Top water on the chart: Creek inflow, an inflow / creek mouth in the 12 ft range, prime in spring. Time it for early morning. Summer baits: a small spinner rig drifted or a 1/8 oz jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Creek inflow (12 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 15 to 40 ft | dawn | Feeding flat (21 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 15 to 45 ft | midday | Offshore hump (15 ft) | Jigging spoon (small), Blade bait |
| Winter | 20 to 50 ft | dusk | Offshore hump (15 ft) | Small rattle spoon, Tungsten + spikes |
The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Creek inflow, an inflow / creek mouth in the 12 ft range, prime in spring. Time it for early morning and the evening. 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 | Creek inflow (12 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Mud Brook inflow (17 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Creek inflow (12 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Mud Brook inflow (17 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Warm water sends them out to 3 to 12 ft; cold water stacks them in 10 to 25 ft. Top water on the chart: Shallow bay flat, a feeding flat in the 9 ft range, prime in summer. Fish it in after dark and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Back-bay flat (5 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (9 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (9 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (108 ft) |
The spring pattern is a shallow one: lake trout in 10 to 40 ft. Midsummer fish sit out in 50 to 120 ft before dropping to 20 to 80 ft for winter. The spot to know is Deep basin, a deep basin in about 108 ft of water that rates prime for lake trout in summer. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
