30,513-acre lake near Standish. The lake tops out around 314 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Below is the species-by-species picture, pulled from the same data the map uses.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. If you only fish one area, make it Dingley Brook inflow: a inflow / creek mouth around 6 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Go-to baits |
|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Jigging spoon, Tube jig (white) |
Spring smallmouth bass on Sebago Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 20 to 45 ft. The spot to know is Rock reef, a rock pile in about 9 ft of water that rates prime for smallmouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Go-to baits |
|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Ned rig, Tube jig |
