80-acre reservoir near Chester. CT DEEP 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. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Pataconk Reservoir runs 80 acres with 1.5 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Figure 0.6 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Lower Connecticut River Valley County. The nearest mapped water is Cedar Lake, 2 mi to the southeast.
Spring puts rainbow trout in skinny water — 4 to 15 ft is the zone. Summer fish stay in 4 to 15 ft, and winter fish hold in 3 to 15 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 12 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 15 ft | dawn & dusk | Break off the point (12 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 4 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 15 ft | dawn | Break off the point (12 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for brown trout tight to the bank in 2 to 15 ft. Through summer count on 5 to 15 ft; the winter hold is 2 to 15 ft. Start at Break off the point. It's a drop-off holding about 12 ft of water and rates prime come summer. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 5 to 15 ft | night & dawn | Break off the point (12 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 15 ft | dusk & dawn | Main-lake point (4 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 2 to 15 ft | dawn | Break off the point (12 ft) | Jigging spoon, Small stickbait (slow) |
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 Shallow bay flat: a weed flat around 6 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft | midday & dawn | Deep basin (14 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 6 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 (6 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 15 ft | midday | Break off the point (12 ft) | Blade bait, Jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 5 to 15 ft for winter. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (6 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 15 ft | midday | Deep basin (14 ft) | Tungsten ice jig + plastic, Tiny 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, 6 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 (6 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (6 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 15 ft | dawn | Shallow bay flat (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
