4,867-acre lake near Bridgton. The lake tops out around 59 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Long Lake runs 5,230 acres with 32.6 miles of edge — 2 islands included. That shoreline is heavily fingered (development index 3.2) — bays, points and pockets everywhere, which multiplies the fishable edge. Littoral water — the productive band under ~15 ft — makes up 59% of this chart, as modeled. Figure 10.8 mi of water from one end to the other, 1.9 mi at the beam. You'll find it in Cumberland County. For a second option, Highland Lake lies 5 mi northwest.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Sharp break (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Sharp break (9 ft) | Blade bait, Jigging spoon |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 20 to 45 ft for winter. Spring smallmouth bass concentrate at Rock reef, a prime-rated rock pile around 7 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Rock reef (7 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Rock reef (7 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Sharp break (9 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Sharp break (9 ft) | Blade bait, Hair jig |
Start shallow in spring: landlocked salmon sit in 1 to 15 ft that time of year. Summer pushes them deeper, 18 to 59 ft, and winter fish settle into 10 to 40 ft. The spot to know is Deepest basin, a deep basin in about 59 ft of water that rates prime for landlocked salmon in summer. 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 | Sharp break (9 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 18 to 59 ft | dawn & dusk | Deepest basin (59 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | Sharp break (9 ft) | Casting spoon at the mouths, Streamers |
| Winter | 10 to 40 ft | dawn | Sharp break (9 ft) | Small jigging spoon, Swedish pimple + smelt |
The chart marks 12 structure features on Long Lake; the deepest is Deepest basin at about 59 ft.
