Rating depth structure for largemouth bass.
Recent public catches load as you reach this section.
31-acre lake near Belmont. NH GRANIT / NH Fish & Game survey water. The lake tops out around 5 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Sargent Lake draws 31 acres inside 0.9 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.3 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Belknap County. For a second option, POUT POND lies 3 mi west.
Spring yellow perch on Sargent Lake hold shallow, usually 1 to 5 ft. Depth-wise the year is flat: 2 to 5 ft in summer, 2 to 5 ft once it turns cold. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
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 | 1 to 5 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 5 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 5 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 5 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts smallmouth bass in skinny water — 1 to 5 ft is the zone. Summer fish stay in 2 to 5 ft, and winter fish hold in 2 to 5 ft. Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 3 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft chart-limited; documented 3 to 12 ft | dawn & dusk | Main-lake point (3 ft) | Ned rig, Tube jig |
| Summer | 2 to 5 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (5 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 5 ft chart-limited; documented 8 to 25 ft | midday & dawn | Main-lake point (3 ft) | Jerkbait, Blade bait |
| Winter | 2 to 5 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (5 ft) | Blade bait, Hair jig |
In spring, largemouth bass run shallow here, mostly 1 to 5 ft. Summer keeps them at 2 to 5 ft, and they winter in 2 to 5 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft chart-limited; documented 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 5 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (2 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 1 to 5 ft chart-limited; documented 4 to 15 ft | midday & dawn | Main-lake point (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 5 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (5 ft) | Blade bait, Jigging spoon |
Start shallow in spring: white perch sit in 1 to 5 ft that time of year. They don't go far with the seasons — 2 to 5 ft covers summer, 2 to 5 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 5 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a small spinner rig drifted or a 1/8 oz jigging spoon until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft chart-limited; documented 4 to 15 ft | dusk | Shallow bay flat (2 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 2 to 5 ft chart-limited; documented 15 to 40 ft | dawn | Deep basin (5 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |

| Winter | 2 to 5 ft chart-limited; documented 20 to 50 ft | dusk | Deep basin (5 ft) | Small rattle spoon, Tungsten + spikes |
Spring puts crappie in skinny water — 1 to 5 ft is the zone. Summer fish stay in 2 to 5 ft, and winter fish hold in 2 to 5 ft. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 5 ft. Warm-month bites cluster around early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.

The spring pattern is a shallow one: bluegill in 1 to 5 ft. The depth story barely changes: 1 to 5 ft through summer, 2 to 5 ft in winter. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.

Sargent Lake is about 5 ft (2 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target yellow perch, smallmouth bass, largemouth bass, white perch, crappie, bluegill, brown bullhead, chain pickerel on Sargent Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species listed for the nearest surveyed lakes in the region, filtered to this lake's depth and habitat.
Shallow bay flat is the top-rated area: a weed flat in about 2 ft of water that rates prime for yellow perch in spring. Every other rated spot, per species and season, is on the map above.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Sargent Lake is regulated by the New Hampshire Fish and Game. Check the official New Hampshire regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
