Quonnipaug Lake is located in the town of Guilford and is a natural lake within the Central Coastal Drainage Basin. The water level was raised 4 feet by a concrete and masonry dam. The watershed is 1,700 acres of mostly wood and wetland with moderate residential development. The lake is fed by Sucker Brook and two small streams. It drains southward into a small tributary of the West River, which flows into Long Island Sound. The eastern shore is heavily developed with residences. Route 77 parallels the western shore, which precludes residential development along this side of the lake. A town beach is located on the western shore.
The transparency of the lake is fair to clear with visibility of 10-13 feet in late summer. The bottom of the lake consists of sand and gravel in the deeper areas. There is mud in the shallows at the northern and southern ends. The fishing in the lake should be good to excellent for trout with a chance for a holdover; good for bullhead; and fair for pickerel and sunfish. Although general bass fishing is only fair there’s potential for tying into a real lunker here. Ice fishing is prohibited.
