26-acre pond near Epsom. NH GRANIT / NH Fish & Game survey water. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Chestnut Pond runs 26 acres with 0.9 miles of edge. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 57% of this chart. Call it 0.4 mi long. You'll find it in Merrimack County. The nearest mapped water is BLAKE POND, 1 mi to the north.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 6 to 20 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (19 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 20 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (19 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: brown bullhead in 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 6 to 20 ft for winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for brown bullhead in winter. Plan around after dark and the evening in the warm months.
