662-acre lake near Searsmont. The lake tops out around 51 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Quantabacook Lake maps at 700 acres behind 9.9 miles of shoreline — one island included. With a shoreline index of 2.7, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 51% of the water is 15 ft or less, the band where the food chain lives. Call it 2.9 mi long by 0.9 mi wide at the broadest reach. It sits in Waldo County. Tilden Pond sits 4 mi east — 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 Bartlett Stream inflow first on the milk run — an inflow / creek mouth near 5 ft that grades prime for spring. 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 | Bartlett Stream inflow (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Bartlett Stream inflow (5 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Bartlett Stream inflow (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Bartlett Stream inflow (5 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, brown trout run shallow here, mostly 3 to 25 ft. Midsummer fish sit out in 15 to 51 ft before dropping to 5 to 35 ft for winter. Spring brown trout concentrate at Bartlett Stream inflow, a prime-rated inflow / creek mouth around 5 ft. Fish it in after dark and early morning and you'll meet the bite. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Bartlett Stream inflow (5 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 15 to 51 ft | night & dawn | Deep basin (48 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Bartlett Stream inflow (5 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 35 ft | dawn | Bartlett Stream inflow (5 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: chain pickerel sit in 2 to 10 ft that time of year. Warm water sends them out to 3 to 15 ft; cold water stacks them in 5 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a weedless spoon + trailer or a buzzbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (2 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow feeding flat (11 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow feeding flat (11 ft) | Jigging spoon (through ice) |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 ft that scores prime in spring. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Secondary point (11 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (7 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Old creek channel (18 ft) | Blade bait, Jigging spoon |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 20 to 45 ft one. Start at Secondary point. It's a point holding about 11 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (7 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Secondary point (11 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Secondary point (11 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Old creek channel (18 ft) | Blade bait, Hair jig |
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 Bartlett Stream inflow first on the milk run — an inflow / creek mouth near 5 ft that grades prime for spring. 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 | Bartlett Stream inflow (5 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 15 to 40 ft | dawn | Shallow feeding flat (11 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 15 to 45 ft | midday | Deep basin (48 ft) | Jigging spoon (small), Blade bait |
| Winter | 20 to 50 ft | dusk | Deep basin (48 ft) | Small rattle spoon, Tungsten + spikes |
