34-acre lake near Whitefield. NH GRANIT / NH Fish & Game survey water. The lake tops out around 20 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.
The drawn water covers 34 acres wrapped in 0.9 miles of bank. The basin is a simple one (shoreline index 1.1) — 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 73% of this chart. End to end it runs roughly 0.3 mi, about 0.2 mi across. It sits in Coos County. If the bite dies, Burns Pond is 3 mi to the southwest.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 6 to 20 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 20 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 20 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Through summer count on 5 to 20 ft; the winter hold is 4 to 20 ft. Start at Deep basin.

A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
