173-acre pond near Grantham. 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. Species by species, here's what the data says the year looks like.
The drawn water covers 173 acres wrapped in 3.1 miles of bank. A middling shoreline index (1.7) gives it some bays to work without being a maze. 58% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 1.5 mi, about 0.3 mi across. It sits in Sullivan County. Its nearest charted neighbour, COLE POND, is 2 mi to the north.
When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 6 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 30 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| 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 |

| Fall | 9 to 30 ft | dawn & dusk | Deep basin (30 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 30 ft | dawn | Deep basin (30 ft) | Jigging spoon, Tube jig (white) |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 30 ft for winter.

You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
