Errol Dam to Pontook; premier NH float water The river tops out around 8 ft. The contours are modeled from the water's real shoreline and maximum depth.

Androscoggin River maps at 402 acres behind 35.7 miles of shoreline, with a single island in the mix. A development index of 12.7 means a maze of bays and points: far more casting targets than a round bowl of the same size. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Call it 12.2 mi long by 2.3 mi wide at the broadest reach. Coos County claims this one. SESSIONS POND sits 0 mi northwest — the closest neighbouring chart.
Spring rainbow trout on Androscoggin River hold shallow, usually 2 to 8 ft. Depth-wise the year is flat: 2 to 8 ft in summer, 2 to 8 ft once it turns cold. Put Current seam (mile 2.5) first on the milk run — a current seam near 4 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dawn & dusk | Current seam (mile 2.5) (4 ft) | Inline spinner (silver), Small spoon |
| Summer | 2 to 8 ft | dawn & dusk | Current seam (mile 2.5) (4 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 2 to 8 ft | dawn & dusk | Current seam (mile 2.5) (4 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 2 to 8 ft | dawn | Current seam (mile 2.5) (4 ft) | Jigging spoon, Tube jig (white) |
When the water first warms, smallmouth bass slide up into 2 to 8 ft. There's no big seasonal slide here — summer means 2 to 8 ft, winter 2 to 8 ft. If you only fish one area, make it Riffle & run (mile 0.6): a rock pile around 3 ft that scores prime in spring. In summer the feeding windows fall in 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 | 2 to 8 ft | dawn & dusk | Riffle & run (mile 0.6) (3 ft) | Ned rig, Tube jig |
| Summer | 2 to 8 ft | dawn & dusk | Riffle & run (mile 0.6) (3 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 8 ft | midday & dawn | Inside bend (mile 10.9) (6 ft) | Jerkbait, Blade bait |
| Winter | 2 to 8 ft | midday | Current seam (mile 2.5) (4 ft) | Blade bait, Hair jig |
Early season brook trout use the shallows, holding in 1 to 8 ft. Even in summer they hold at 2 to 8 ft; winter keeps them in 1 to 8 ft. The chart's best answer is Current seam (mile 2.5) — current seam, 4 ft, prime for spring. Best bite is 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 | 1 to 8 ft | dawn & dusk | Current seam (mile 2.5) (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 8 ft | dawn & dusk | Current seam (mile 2.5) (4 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 8 ft | midday & dawn | Current seam (mile 2.5) (4 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 8 ft | dawn | Current seam (mile 2.5) (4 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, brown trout run shallow here, mostly 1 to 8 ft. Summer keeps them at 2 to 8 ft, and they winter in 1 to 8 ft. Current seam (mile 2.5) is the standout, a current seam at roughly 4 ft, rated prime for summer brown trout. Time it for after dark and early morning. 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 | 1 to 8 ft | dawn & dusk | Eddy pocket (mile 15.0) (6 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

| Winter | 1 to 8 ft | dawn | Eddy pocket (mile 15.0) (6 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: rock bass sit in 2 to 8 ft that time of year. They don't go far with the seasons — 2 to 8 ft covers summer, 2 to 8 ft covers winter. Top water on the chart: Riffle & run (mile 0.6), a rock pile in the 3 ft range, prime in spring. Fish it in the evening and you'll meet the bite. Throw a ned rig (small) or a marabou jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Riffle & run (mile 0.6) (3 ft) | 1/16 oz jig + grub, Small inline spinner |

The spot to know is Current seam (mile 2.5), a current seam in about 4 ft of water that rates good for chain pickerel in fall. Warm-month bites cluster around early morning and the evening. Throw a weedless spoon + trailer or a buzzbait until the fish tell you otherwise.
