235-acre lake near Webster. NH GRANIT / NH Fish & Game survey water. The lake tops out around 60 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. Species by species, here's what the data says the year looks like.
Winnepocket Lake maps at 235 acres behind 2.9 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. About 50% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 1.3 mi, about 0.4 mi across. Merrimack County claims this one. Its nearest charted neighbour, LITTLE POND (MERRIMACK), is 2 mi to the northeast.
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. The chart's best answer is Shallow bay flat — weed flat, 5 ft, good for spring. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (5 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow feeding flat (20 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 20 to 45 ft. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | open water | Blade bait, Hair jig |
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 5 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (5 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (5 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | open water | Blade bait, Jigging spoon |
When the water first warms, brown bullhead slide up into 2 to 8 ft. Summer is a 3 to 12 ft game here, winter a 10 to 25 ft one. Start at Shallow bay flat. It's a weed flat holding about 5 ft of water and rates prime come spring. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (5 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (5 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (5 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (60 ft) |
The spring pattern is a shallow one: chain pickerel in 2 to 10 ft. As the season builds they drop to 3 to 15 ft, wintering in 5 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a weedless spoon + trailer or a buzzbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (5 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (5 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (5 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow bay flat (5 ft) | Jigging spoon (through ice) |
4 pieces of structure are mapped here — Deep basin, around 60 ft, is the deepest of them.
