1,415-acre lake near Monmouth. The lake tops out around 49 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Annabessacook Lake runs 1,414 acres with 17 miles of edge, with 8 islands in the mix. A development index of 3.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 47% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 3.7 mi long by 1.8 mi wide at the broadest reach. The water lies in Kennebec County. The nearest mapped water is Cobbosseecontee Lake, 3 mi to the east.
Spring chain pickerel on Annabessacook Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 3 to 15 ft, and by winter most fish are in 5 to 18 ft. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Prime time lands in 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 | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (1 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow feeding flat (18 ft) | Jigging spoon (through ice) |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 15 to 35 ft. Winter largemouth bass concentrate at Break off the point, a prime-rated drop-off around 17 ft. Warm-month bites cluster around early morning and the evening. 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 (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (17 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (17 ft) | Blade bait, Jigging spoon |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 20 to 45 ft. Break off the point is the standout, a drop-off at roughly 17 ft, rated prime for summer smallmouth bass. Time it for early morning and the evening. 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 | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (17 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (17 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (17 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: white perch in 4 to 15 ft. Midsummer fish sit out in 15 to 40 ft before dropping to 15 to 49 ft for winter. The spot to know is Deep basin, a deep basin in about 48 ft of water that rates prime for white perch in winter. Plan around early morning in the warm months. Summer baits: a small spinner rig drifted or a 1/8 oz jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Wilson Stream inflow (1 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 15 to 40 ft | dawn | Shallow feeding flat (19 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 15 to 45 ft | midday | Break off the point (17 ft) | Jigging spoon (small), Blade bait |
| Winter | 15 to 49 ft | dusk | Deep basin (48 ft) | Small rattle spoon, Tungsten + spikes |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 10 to 25 ft. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates prime for brown bullhead in spring. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (1 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (1 ft) | |
| Fall | 5 to 15 ft | dusk | open water | |
| Winter | 10 to 25 ft | midday | Old creek channel (23 ft) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Break off the point is the standout, a drop-off at roughly 17 ft, rated prime for fall northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
