196-acre lake near Sutton. NH GRANIT / NH Fish & Game survey water. The lake tops out around 40 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.
Drawn out, this is 196 acres of water rimmed by 2.6 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. 45% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 1.2 mi end to end and 0.4 mi across at its widest. You'll find it in Merrimack County. The nearest mapped water is Billings Pond, 0 mi to the southwest.
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 12 to 40 ft. Top water on the chart: Main-lake point, a point in the 9 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (9 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (9 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (9 ft) | Jerkbait, Blade bait |
| Winter | 12 to 40 ft | midday | Break off the point (6 ft) | Blade bait, Hair jig |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 10 to 25 ft for winter. Spring brown bullhead concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in after dark and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Back-bay flat (10 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (39 ft) |
When the water first warms, chain pickerel slide up into 2 to 10 ft. Summer is a 3 to 15 ft game here, winter a 5 to 18 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a weedless spoon + trailer or a buzzbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
