34-acre reservoir near Haddam. CT DEEP survey water. The lake tops out around 30 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.
The outline encloses 34 acres, worked by 1.4 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 57% of this chart. Tip to tip the water measures near 0.7 mi. It sits in Lower Connecticut River Valley County. Its nearest charted neighbour, Millers Pond, is 4 mi to the west.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 6 to 30 ft. Start at Break off the point. It's a drop-off holding about 20 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (20 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 30 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 30 ft | dawn | Break off the point (20 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Warm water sends them out to 9 to 30 ft; cold water stacks them in 4 to 30 ft. Top water on the chart: Break off the point, a drop-off in the 20 ft range, prime in summer. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (9 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 30 ft | night & dawn | Break off the point (20 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (9 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 30 ft | dawn | Break off the point (20 ft) | Jigging spoon, Small stickbait (slow) |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 9 to 30 ft.

A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
