Suncook Lakes

The Suncook Lakes are a pair of lakes located in Belknap County in central New Hampshire, United States, in the town of Barnstead. Upper Suncook Lake encompasses 402 acres (1.63 km²), while Lower Suncook Lake covers 295 acres (1.19 km²). The lakes are connected by a 1,000-foot-long (300 m) channel, spanned by a road bridge. A dam at the outlet of Lower Suncook Lake controls the water level of both lakes. The lakes are located along the Suncook River, a tributary of the Merrimack River. There are three islands on Lower Lake.
