914-acre lake near Rindge. NH GRANIT / NH Fish & Game survey water. The lake tops out around 25 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 914 acres wrapped in 5.3 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. About 79% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 2.3 mi long by 1 mi wide at the broadest reach. Cheshire County claims this one. Its nearest charted neighbour, PECKER POND, is 2 mi to the east.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 8 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
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 | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 25 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (22 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 25 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (22 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 25 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (22 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring largemouth bass on Monomonac Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 8 to 25 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Back-bay flat (4 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Back-bay flat (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 8 to 25 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (22 ft) | Blade bait, Jigging spoon |
Come spring, look for white perch tight to the bank in 4 to 15 ft. They move out to 8 to 25 ft in summer and finish the year down in 8 to 25 ft. If you only fish one area, make it Deep basin: a deep basin around 22 ft that scores prime in summer. Best bite is early morning. A small spinner rig drifted or a 1/8 oz jigging spoon is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Back-bay flat (4 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 8 to 25 ft chart-limited; documented 15 to 40 ft | dawn | Deep basin (22 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 8 to 25 ft chart-limited; documented 15 to 45 ft | midday | Deep basin (22 ft) | Jigging spoon (small), Blade bait |
| Winter | 8 to 25 ft chart-limited; documented 20 to 50 ft | dusk | Deep basin (22 ft) | Small rattle spoon, Tungsten + spikes |
Early season crappie use the shallows, holding in 2 to 8 ft. Expect a summer slide to 10 to 25 ft, then a winter hold in 8 to 25 ft. Put Deep basin first on the milk run — a deep basin near 22 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Deep basin (22 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow feeding flat (20 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 8 to 25 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (22 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season bluegill use the shallows, holding in 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 10 to 25 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Back-bay flat (4 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Back-bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (22 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, pumpkinseed run shallow here, mostly 1 to 8 ft. Midsummer fish sit out in 2 to 10 ft before dropping to 6 to 18 ft for winter. Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a micro tube or a sponge spider (fly) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Back-bay flat (4 ft) | Tungsten ice jig + plastic, Tiny spoon |

Shallow bay flat is the top-rated area: a weed flat in about 3 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.
