31-acre lake near Belmont. NH GRANIT / NH Fish & Game survey water. The lake tops out around 5 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. 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 5 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 5 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |

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 | dawn & dusk | Main-lake point (3 ft) | Ned rig, Tube jig |
| Summer | 2 to 5 ft | dawn & dusk | Break off the point (5 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 5 ft | midday & dawn | Main-lake point (3 ft) | Jerkbait, Blade bait |

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 | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |

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.

| Spring | 1 to 5 ft | dusk | Shallow bay flat (2 ft) | Small jig + curly tail, Inline spinner (silver) |
