Description
The Suncook River is a 35.7-mile-long (57.5 km) river located in central New Hampshire in the United States. It is a tributary of the Merrimack River, which flows to the Gulf of Maine. The Suncook River begins at the outlet of Crystal Lake in the town of Gilmanton, New Hampshire. The village of Gilmanton Ironworks is located at the lake's outlet. The Suncook flows south two miles to the Suncook Lakes (Upper and Lower) in Barnstead. Below the lakes, the river passes through the village of Center Barnstead and enters the town of Pittsfield, whose village is centered on a 19th century dam on the river. The river continues south through the towns of Chichester and Epsom, and then forms the town boundary between Pembroke and Allenstown. Shortly before reaching the Merrimack River, the Suncook drops 70 feet (21 m) in 0.5 miles (0.80 km), a natural waterpower site that led to the growth of the village of Suncook.
