607-acre reservoir near East Haddam. CT DEEP survey water. The lake tops out around 9 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 607 acres, worked by 4 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 1.6 mi long by 0.8 mi wide at the broadest reach. It sits in Lower Connecticut River Valley County. Bashan Lake sits 1 mi southwest — the closest neighbouring chart.
In spring, yellow perch run shallow here, mostly 2 to 9 ft. Summer keeps them at 3 to 9 ft, and they winter in 3 to 9 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
