Lying in the Fairfield County towns of Sherman and New Fairfield, Squantz Pond is part of Candlewood Lake but is separated from the main body of the lake by Route 39. Squantz Pond is natural in origin; however, its level was raised when Candlewood Lake was impounded in 1923. The lake has a surface area of approximately 288 acres (1.2 km²), a maximum depth of 47 feet (14 m), an average depth of 22.9 feet (7 m), and holds approximately 2 billion US gallons (7,600,000 m³) of water.The shoreline bottom materials consist mostly of rocks, ledge, and gravel. Mud and organic muck cover the relatively flat areas of the bottom. The lake is fed by Glen Brook from the north, Worden Brook from the west, and several small unnamed streams.The watershed of Squantz Pond is 3,635 acres (15 km²). Woodlands, wetlands, and water comprise approximately 80 percent of the watershed, 15 percent is moderate to low-density housing, while the remaining 5 percent is open land and farm land.The eastern shoreline is developed with homes, while the western shoreline is steep and wooded. The southwestern shoreline borders Squantz Pond State Park. Facilities in the park include concession stands, picnic areas, beach and swimming areas, toilets, and hiking trails.Public access to Squantz Pond is provided through a state owned boat launch located in the State Park. Boats launched from the State Park are limited to a maximum of 7.5 horsepower (6 kW). The launch can be reached by taking Interstate 84, Exit 5 to Route 37 north, to Route 39 north to the State Park entrance.
