1,652-acre lake in Maine. The lake tops out around 25 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 1,649 acres wrapped in 16.8 miles of bank. With a shoreline index of 2.9, this water is all arms and coves — edge habitat well beyond its acreage. Littoral water — the productive band under ~15 ft — makes up 82% of this chart, as modeled. Call it 4.2 mi long by 1.6 mi wide at the broadest reach. If the bite dies, Duck Lake is 5 mi to the west.
When the water first warms, rainbow trout slide up into 5 to 20 ft. Summer is a 7 to 25 ft game here, winter a 5 to 25 ft one. Start at Break off the point. It's a drop-off holding about 11 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 7 to 25 ft | dawn & dusk | Break off the point (11 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 25 ft | dawn | Break off the point (11 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: brown trout in 3 to 25 ft. The depth story barely changes: 8 to 25 ft through summer, 4 to 25 ft in winter. Top water on the chart: Break off the point, a drop-off in the 11 ft range, prime in summer. Time it for after dark and early morning. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 8 to 25 ft | night & dawn | Break off the point (11 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 4 to 25 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 25 ft | dawn | Break off the point (11 ft) | Jigging spoon, Small stickbait (slow) |
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 8 to 25 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 21 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 25 ft | dawn & dusk | Deep basin (21 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (11 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 8 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 25 ft | dawn | Deep basin (21 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 25 ft | midday | Deep basin (21 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 25 ft | midday & dawn | Deep basin (21 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 21 ft.
