62-acre pond near Washington. NH GRANIT / NH Fish & Game survey water. The lake tops out around 15 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. The rest of this page walks each species through its year, using the map's own scoring.
Halfmoon Pond maps at 62 acres behind 1.2 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Tip to tip the water measures near 0.4 mi with a 0.3-mi widest point. Sullivan County claims this one. Island Pond (Washington) sits 1 mi east — the closest neighbouring chart.
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 5 to 15 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 8 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 (8 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft | dawn & dusk | Shallow bay flat (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 15 ft | midday | Deep basin (15 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 5 to 15 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 8 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 12 ft | midday & dawn | Shallow bay flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
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 4 to 15 ft. The spot to know is Shallow bay flat, a weed flat in about 8 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 (8 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (8 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (8 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 4 to 15 ft | dawn | Shallow bay flat (8 ft) | Jigging spoon (through ice) |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Back-bay flat: a weed flat around 4 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 | Back-bay flat (4 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (8 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 5 to 15 ft | midday | Shallow bay flat (8 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 15 ft | midday | Deep basin (15 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, crappie slide up into 2 to 8 ft. By summer they slide out to 5 to 15 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Deep basin: a deep basin around 15 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (8 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 5 to 15 ft | dawn & dusk | Shallow bay flat (8 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 15 ft | dawn | Shallow bay flat (8 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 15 ft | midday | Deep basin (15 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
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 5 to 15 ft. If you only fish one area, make it Deep basin: a deep basin around 15 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 (8 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (8 ft) | |
