Sugar River
The Sugar River is a 66-mile long river that flows through central New Hampshire. It has a rich history dating back to the 18th century when it was used as a major transportation route for logging and farming. Today, the river is primarily used for recreational activities such as fishing, boating, and swimming. Its hydrology is influenced by three major reservoirs: Blaisdell Lake, Highland Lake, and Webster Lake. These reservoirs are managed by the Army Corps of Engineers and provide hydroelectric power and water supply for surrounding communities. The river also supports agricultural uses, with farms located along its banks producing crops such as corn, hay, and vegetables. The Sugar River plays an important role in both the natural and cultural history of New Hampshire, and continues to be a valuable resource for the state.
