166-acre reservoir near Dublin. NH GRANIT / NH Fish & Game survey water. The lake tops out around 10 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. What follows comes from the same scoring engine that paints the spots above.
Howe Reservoir maps at 166 acres behind 2.4 miles of shoreline. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 1.1 mi with a 0.4-mi widest point. Cheshire County claims this one. Its nearest charted neighbour, RUSSELL RESERVOIR, is 1 mi to the northwest.
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Through summer count on 3 to 10 ft; the winter hold is 3 to 10 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in 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 (3 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 10 ft | midday | Deep basin (10 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: yellow perch in 3 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: chain pickerel sit in 2 to 10 ft that time of year. They don't go far with the seasons — 2 to 10 ft covers summer, 3 to 10 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 3 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 (3 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 3 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 3 to 10 ft | dawn | Shallow bay flat (3 ft) | Jigging spoon (through ice) |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. They move out to 3 to 10 ft in summer and finish the year down in 3 to 10 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 3 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 3 to 10 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 10 ft | midday | Deep basin (10 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season white perch use the shallows, holding in 3 to 10 ft. Even in summer they hold at 3 to 10 ft; winter keeps them in 3 to 10 ft. The chart's best answer is Deep basin — deep basin, 10 ft, prime for summer. Best bite is early morning. Tie on a small spinner rig drifted or a 1/8 oz jigging spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | dusk | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 3 to 10 ft | dawn | Deep basin (10 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 3 to 10 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Blade bait |
| Winter | 3 to 10 ft | dusk | Deep basin (10 ft) | Small rattle spoon, Tungsten + spikes |
Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. They move out to 3 to 10 ft in summer and finish the year down in 3 to 10 ft. If you only fish one area, make it Deep basin: a deep basin around 10 ft that scores prime in winter. 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 (3 ft) | |
| Summer | 3 to 10 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 3 to 10 ft | dusk | Deep basin (10 ft) | |
| Winter | 3 to 10 ft | midday | Deep basin (10 ft) |
