Mount Sunapee - Hydrology

Hydrology

The ridgeline of Sunapee Mountain forms the divide between the Merrimack River and Connecticut River watersheds. Lake Solitude, a 4.61-acre (1.87 ha) body of water, lies just 1,000 feet (300 m) southeast of the White Ledges summit, at an elevation of 2,510 feet (770 m). The lake flows into Andrew Brook, a tributary of the Warner River in the Merrimack River watershed. Farther south along the ridge, the east slopes of the mountain drain via the West Branch of the Warner River into the Warner and Merrimack rivers.

The northern and western sides of the mountain drain to the Connecticut River. Johnson Brook flows down the north slopes of the mountain, entering Lake Sunapee, the outlet of which (the Sugar River) flows west to the Connecticut in Claremont. On the western slopes of the mountain, Gunnison Brook, Blood Brook, and Baker Brook flow to the South Branch of the Sugar River. The southwestern end of the mountain drains via Cherry Brook into the headwaters of the Ashuelot River, which reaches the Connecticut River near the Massachusetts border.
