987-acre lake near Bowdoin College Grant West Township. The lake tops out around 64 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 drawn water covers 983 acres wrapped in 11.7 miles of bank, with 7 islands in the mix. The 2.7 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 62% of the surface — that's where the groceries are. The basin spans about 2.2 mi end to end and 1.5 mi across at its widest. It sits in Piscataquis County. Little Mud Pond sits 2 mi northwest — the closest neighbouring chart.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 30 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (15 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (15 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Back-bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, burbot slide up into 19 to 64 ft. There's no big seasonal slide here — summer means 19 to 64 ft, winter 15 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 61 ft that scores prime in spring. In summer the feeding windows fall in after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 19 to 64 ft | night & dusk | Deep basin (61 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 19 to 64 ft | night & midday | Deep basin (61 ft) | Heavy jig + cut bait |
| Fall | 19 to 64 ft | night & dusk | Deep basin (61 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (61 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 19 to 64 ft, and by winter most fish are in 16 to 64 ft. If you only fish one area, make it Deep basin: a deep basin around 61 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 19 to 64 ft | dawn | Deep basin (61 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (15 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 16 to 64 ft | dawn | Deep basin (61 ft) | White tube jig, Airplane jig |
Spring landlocked salmon on Upper Wilson Pond hold shallow, usually 1 to 15 ft. By summer they slide out to 25 to 60 ft, and by winter most fish are in 10 to 40 ft. The chart's best answer is Deep basin — deep basin, 61 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a dodger + streamer down deep or a thin spoon on lead core.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & dusk | Main-lake point (15 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 25 to 60 ft | dawn & dusk | Deep basin (61 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon at the mouths, Streamers |
| Winter | 10 to 40 ft | dawn | Break off the point (30 ft) | Small jigging spoon, Swedish pimple + smelt |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Summer pushes them deeper, 2 to 10 ft, and winter fish settle into 6 to 18 ft. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for pumpkinseed in spring. Warm-month bites cluster around the evening and early morning. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (2 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (2 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Back-bay flat (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season white perch use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 40 ft, then a winter hold in 20 to 50 ft. Put Break off the point first on the milk run — a drop-off near 30 ft that grades prime for fall. In summer the feeding windows fall in early morning. Tie on a small spinner rig drifted or a 1/8 oz jigging spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Back-bay flat (6 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 15 to 40 ft | dawn | Break off the point (30 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 15 to 45 ft | midday | Break off the point (30 ft) | Jigging spoon (small), Blade bait |
| Winter | 20 to 50 ft | dusk | Break off the point (30 ft) | Small rattle spoon, Tungsten + spikes |
