Bellamy Reservoir is a 333-acre (135 ha)[1] impoundment located in Strafford County in eastern New Hampshire, United States, in the town of Madbury. An eastern arm of the lake extends a short distance into Dover. The reservoir serves as the primary water supply for the city of Portsmouth, New Hampshire. Its outlet is the Bellamy River, a tributary of Great Bay, a tidal estuary connected to the Atlantic Ocean by the Piscataqua River.

The reservoir is classified as a warmwater fishery, with observed species including largemouth bass, chain pickerel, horned pout, and black crappie.[1]
