1,105-acre lake near Mount Vernon. The lake tops out around 117 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Echo Lake maps at 1,106 acres behind 14.2 miles of shoreline, with 7 islands in the mix. The 3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 36% of the surface — that's where the groceries are. Figure 3.3 mi of water from one end to the other, 1.5 mi at the beam. It sits in Kennebec County. If the bite dies, Annabessacook Lake is 11 mi to the south.
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 Main-lake point first on the milk run — a point near 6 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 | Main-lake point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Back-bay flat (5 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, burbot slide up into 25 to 70 ft. By summer they slide out to 35 to 117 ft, and by winter most fish are in 15 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 108 ft that scores prime in summer. In summer the feeding windows fall in after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (108 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 35 to 117 ft | night & midday | Deep basin (108 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (108 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (108 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 35 to 117 ft, and by winter most fish are in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 108 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Secondary point (11 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 35 to 117 ft | dawn | Deep basin (108 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (11 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (108 ft) | White tube jig, Airplane jig |
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 (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Old creek channel (13 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 (6 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 | open water | Blade bait, Hair jig |
Come spring, look for splake tight to the bank in 5 to 25 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 10 to 45 ft. Start at Secondary point. It's a point holding about 11 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (6 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Deep basin (108 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Secondary point (11 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Deep basin (108 ft) | Jigging spoon tipped with minnow head, Small white tube |
