156-acre lake near Piermont. NH GRANIT / NH Fish & Game survey water. The lake tops out around 30 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.
The outline encloses 156 acres, worked by 2.2 miles of shoreline. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. About 58% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1 mi long by 0.3 mi wide at the broadest reach. Grafton County claims this one. Its nearest charted neighbour, Tarleton Lake, is 1 mi to the north.
Spring rainbow trout on Armington Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 6 to 30 ft. Put Break off the point first on the milk run — a drop-off near 15 ft that grades prime for winter. 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 | 5 to 20 ft | dawn & dusk | Secondary point (13 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (15 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 30 ft | dawn & dusk | Secondary point (13 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 30 ft | dawn | Break off the point (15 ft) | Jigging spoon, Tube jig (white) |
In spring, brown trout run shallow here, mostly 3 to 25 ft. Summer pushes them deeper, 9 to 30 ft, and winter fish settle into 4 to 30 ft. Break off the point is the standout, a drop-off at roughly 15 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 | 3 to 25 ft | dawn & dusk | Main-lake point (3 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 30 ft | night & dawn | Break off the point (15 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Secondary point (13 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 30 ft | dawn | Break off the point (15 ft) | Jigging spoon, Small stickbait (slow) |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 9 to 30 ft. If you only fish one area, make it Secondary point: a point around 13 ft that scores prime in fall. 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 | 3 to 12 ft | dawn & dusk | Main-lake point (3 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (15 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Secondary point (13 ft) | Jerkbait, Blade bait |
| Winter | 9 to 30 ft | midday | Break off the point (15 ft) | Blade bait, Hair jig |
Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. They move out to 3 to 12 ft in summer and finish the year down in 10 to 25 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (4 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (4 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (4 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (30 ft) |
Start shallow in spring: chain pickerel sit in 2 to 10 ft that time of year. Summer pushes them deeper, 3 to 15 ft, and winter fish settle into 5 to 18 ft. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for chain pickerel in spring. Warm-month bites cluster around early morning and the evening. Throw a weedless spoon + trailer or a buzzbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (4 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (4 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow bay flat (4 ft) | Jigging spoon (through ice) |
