1,152-acre lake near Dexter. The lake tops out around 85 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 1,153 acres of water rimmed by 11.9 miles of bank, with 2 islands in the mix. That shoreline is heavily fingered (development index 2.5) — bays, points and pockets everywhere, which multiplies the fishable edge. The shallow band under 15 ft claims about 35% of the surface — that's where the groceries are. Tip to tip the water measures near 3.7 mi with a 1.3-mi widest point. You'll find it in Penobscot County. For a second option, Big Indian Pond lies 8 mi southwest.
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: East Branch Sebasticook River inflow, an inflow / creek mouth in the 2 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 | East Branch Sebasticook River inflow (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | East Branch Sebasticook River inflow (2 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | East Branch Sebasticook River inflow (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | East Branch Sebasticook River inflow (2 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: lake trout in 10 to 40 ft. Midsummer fish sit out in 26 to 85 ft before dropping to 20 to 80 ft for winter. The spot to know is Deep basin, a deep basin in about 84 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.
| 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 | 26 to 85 ft | dawn | Deep basin (84 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 | Deep basin (84 ft) | White tube jig, Airplane jig |
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 East Branch Sebasticook River inflow, an inflow / creek mouth in about 2 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 | East Branch Sebasticook River inflow (2 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (69 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | East Branch Sebasticook River inflow (2 ft) | Casting spoon at the mouths, Streamers |
| Winter | 10 to 40 ft | dawn | Main-lake point (19 ft) | Small jigging spoon, Swedish pimple + smelt |
In spring, crappie run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 10 to 25 ft before dropping to 15 to 35 ft for winter. Winter crappie concentrate at Old creek channel, a prime-rated creek channel around 35 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Shallow bay flat (11 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (11 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Old creek channel (35 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
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: Back-bay flat, a weed flat in the 2 ft range, prime in spring. 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 (2 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (11 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (11 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (84 ft) |
Spring chain pickerel on Lake Wassookeag hold shallow, usually 2 to 10 ft. They move out to 3 to 15 ft in summer and finish the year down in 5 to 18 ft. Put Back-bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a weedless spoon + trailer or a buzzbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Back-bay flat (2 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (11 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (11 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow bay flat (11 ft) | Jigging spoon (through ice) |
