1,547-acre lake near Bridgewater. The lake tops out around 60 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. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 1,597 acres, worked by 35.2 miles of shoreline, broken up by an island. With a shoreline index of 6.3, this water is all arms and coves — edge habitat well beyond its acreage. About 34% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 8.5 mi end to end and 3.6 mi across at its widest. Western Connecticut County claims this one. Its nearest charted neighbour, Candlewood Lake, is 5 mi to the west.
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 11 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
