Rating depth structure for largemouth bass.

52-acre pond near Sanbornton. NH GRANIT / NH Fish & Game survey water. The lake tops out around 15 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 52 acres of water rimmed by 1.5 miles of bank. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. End to end it runs roughly 0.7 mi, about 0.2 mi across. You'll find it in Belknap County. The nearest mapped water is Webster Lake, 2 mi to the southwest.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 5 to 15 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Back-bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
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 | 3 to 12 ft | midday & dawn | Back-bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 5 to 15 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Back-bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Back-bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (10 ft) | Blade bait, Jigging spoon |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (2 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (2 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 15 ft chart-limited; documented 6 to 18 ft | dawn | Deep basin (10 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 5 to 15 ft for winter. Winter brown bullhead concentrate at Deep basin, a prime-rated deep basin around 10 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 (2 ft) | |
| Summer | 3 to 12 ft | night & dusk | Back-bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Deep basin (10 ft) | |
| Winter | 5 to 15 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (10 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 4 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 2 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.

Anglers target yellow perch, largemouth bass, pumpkinseed, brown bullhead, chain pickerel on Giles Pond.
Back-bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Scroll up to the map for the complete spot list by species and season.
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.
