53-acre lake near Lisbon. 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. Here's the year, species by species, as the scoring engine sees it.
On the chart, Pearl Lake draws 53 acres inside 1.2 miles of shoreline. 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. Roughly 86% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 0.4 mi, about 0.3 mi across. You'll find it in Grafton County. Closest neighbour on DepthScout: Ogontz Lake, 5 mi northwest of here.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer keeps them at 5 to 20 ft, and they winter in 4 to 20 ft. Deep basin is the standout, a deep basin at roughly 20 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 20 ft | dawn & dusk | Deep basin (20 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 20 ft | dawn & dusk | Deep basin (20 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 20 ft | dawn | Deep basin (20 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. Midsummer fish sit out in 6 to 20 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 good for smallmouth bass in winter. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 6 to 20 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 20 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) | Blade bait, Hair jig |
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 12 ft; cold water stacks them in 6 to 20 ft. Deep basin is the standout, a deep basin at roughly 20 ft, rated prime for winter brown bullhead. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (1 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (1 ft) | |
| Fall | 5 to 15 ft | dusk | open water | |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) |
Come spring, look for chain pickerel tight to the bank in 2 to 10 ft. They move out to 3 to 15 ft in summer and finish the year down in 5 to 18 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. Best bite is early morning and the evening. A weedless spoon + trailer or a buzzbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (1 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow bay flat (1 ft) | Jigging spoon (through ice) |
3 pieces of structure are mapped here — Deep basin, around 20 ft, is the deepest of them.
