135-acre lake near North Stonington. CT DEEP survey water. The lake tops out around 9 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Lake Of Isles maps at 135 acres behind 2 miles of shoreline. 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. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Tip to tip the water measures near 0.9 mi with a 0.4-mi widest point. It sits in Southeastern Connecticut County. Lantern Hill Pond sits 2 mi south — the closest neighbouring chart.
The spring pattern is a shallow one: yellow perch in 2 to 9 ft. The depth story barely changes: 3 to 9 ft through summer, 3 to 9 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
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 | 2 to 9 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 9 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 9 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 9 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for largemouth bass tight to the bank in 2 to 9 ft. Through summer count on 3 to 9 ft; the winter hold is 3 to 9 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 ft that scores prime in spring. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft chart-limited; documented 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 9 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Back-bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 9 ft chart-limited; documented 4 to 15 ft | midday & dawn | Main-lake point (2 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 9 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (6 ft) | Blade bait, Jigging spoon |
Early season white perch use the shallows, holding in 2 to 9 ft. Even in summer they hold at 3 to 9 ft; winter keeps them in 3 to 9 ft. Put Deep basin first on the milk run — a deep basin near 9 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a small spinner rig drifted or a 1/8 oz jigging spoon and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft chart-limited; documented 4 to 15 ft | dusk | Shallow bay flat (2 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 3 to 9 ft chart-limited; documented 15 to 40 ft | dawn | Deep basin (9 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 3 to 9 ft chart-limited; documented 15 to 45 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Blade bait |
| Winter | 3 to 9 ft chart-limited; documented 20 to 50 ft | dusk | Deep basin (9 ft) | Small rattle spoon, Tungsten + spikes |
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 3 to 9 ft game here, winter a 3 to 9 ft one. Start at Deep basin. It's a deep basin holding about 9 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 3 to 9 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Back-bay flat (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 3 to 9 ft chart-limited; documented 8 to 20 ft | dawn | Back-bay flat (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 3 to 9 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (9 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. Expect a summer slide to 2 to 9 ft, then a winter hold in 3 to 9 ft. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 2 to 9 ft chart-limited; documented 4 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 3 to 9 ft chart-limited; documented 6 to 18 ft | midday | Back-bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 9 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (9 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Summer pushes them deeper, 2 to 9 ft, and winter fish settle into 3 to 9 ft. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for pumpkinseed in spring. Warm-month bites cluster around the evening and early morning. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
