About the ashuelot river


The Ashuelot River is a 64-mile-long river in southwestern New Hampshire. The river flows through several towns, including Ashuelot, Winchester, Hinsdale, and Swanzey. The river's hydrology is largely influenced by the many dams and reservoirs along its length. The two largest reservoirs are the Highland Lake and the Surry Mountain Lake. The river has historically been used for water-powered mills, and today it is used for hydroelectric power generation. Additionally, the river provides opportunities for recreational activities such as fishing, canoeing, and kayaking. The river is also used for agricultural irrigation in some areas. The Ashuelot River is an important natural resource for the region and is home to a variety of fish species, including trout, smallmouth bass, and walleye.
