88-acre lake near Killingly. CT DEEP survey water. The lake tops out around 28 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.
On the chart, Quinebaug Lake draws 88 acres inside 1.8 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 56% of the surface — that's where the groceries are. End to end it runs roughly 0.8 mi, about 0.2 mi across. The water lies in Northeastern Connecticut County. The nearest mapped water is Moosup Pond, 3 mi to the south.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 3 to 20 ft for winter. The spot to know is Deep basin, a deep basin in about 28 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 28 ft | dawn & dusk | Deep basin (28 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (14 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 7 to 28 ft; cold water stacks them in 6 to 28 ft. Top water on the chart: Break off the point, a drop-off in the 14 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.

Spring brown trout on Quinebaug Lake hold shallow, usually 3 to 25 ft. They move out to 8 to 28 ft in summer and finish the year down in 4 to 28 ft.

The summer box starts with a spoon at the thermocline or a deep stickbait (night).

Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 8 to 28 ft, then a winter hold in 8 to 28 ft. Put Shallow bay flat first on the milk run — a weed flat near 9 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (9 ft) | Small jig + curly tail, Perch-pattern micro crank |

You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
