Moore Dam is a major hydroelectric dam on the Upper Connecticut River between Grafton County, New Hampshire and Caledonia County, Vermont in the northeastern United States. The dam is located near Littleton, New Hampshire, and forms the 3,490-acre (1,410 ha) Moore Reservoir. The Moore Station is the largest conventional hydroelectric plant in New England,[4] in terms of installed capacity and average power generation. The dam and reservoir also provide flood control, recreational boating and fishing.

The official name of the dam is the Samuel C. Moore Dam, after a former president of the now defunct New England Power Company that originally built it. The dam, reservoir and power station are now owned and operated by TransCanada Corporation.
