Rating depth structure for brook trout.
Recent public catches load as you reach this section.
1,002-acre lake near Sinclair Township. The lake tops out around 20 ft. The depth chart comes from Maine Department of Environmental Protection bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 1,001 acres of water rimmed by 7.2 miles of bank. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. 79% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 2.3 mi, about 1.3 mi across. You'll find it in Aroostook County. For a second option, Cross Lake lies 4 mi southwest.
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.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 20 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 20 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (4 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts landlocked salmon in skinny water — 1 to 15 ft is the zone. As the season builds they drop to 6 to 20 ft, wintering in 5 to 20 ft. Summer landlocked salmon concentrate at Deep basin, a prime-rated deep basin around 20 ft. Warm-month bites cluster around early morning and the evening. 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 | Main-lake point (4 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 6 to 20 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Deep basin (20 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 3 to 20 ft chart-limited; documented 5 to 30 ft | dawn & dusk | Main-lake point (4 ft) | Casting spoon at the mouths, Streamers |
| Winter | 5 to 20 ft chart-limited; documented 10 to 40 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Swedish pimple + smelt |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 6 to 20 ft for winter. Winter brown bullhead concentrate at Deep basin, a prime-rated deep basin around 20 ft. 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 | Shallow bay flat (2 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (2 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow feeding flat (16 ft) | |
| Winter | 6 to 20 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (20 ft) |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 6 to 20 ft in summer and finish the year down in 6 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 20 ft that scores prime in fall. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.

Mud Lake is about 20 ft (6 m) deep at its deepest point. The depth chart comes from Maine Department of Environmental Protection bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target brook trout, landlocked salmon, brown bullhead, yellow perch on Mud Lake.
Deep basin is the top-rated area: a deep basin in about 20 ft of water that rates prime for landlocked salmon in summer. Every other rated spot, per species and season, is on the map above.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
