April 15, 2011 - Moore Dam in New Hampshire

Where is the largest conventional hydroelectric dam in New England?

Built in 1957 at 178' in height and featuring 192 megawatts of capacity, the Samuel C. Moore Dam on the upper Connecticut River in northern New Hampshire and Vermont is the largest conventional hydro facility in New England.  Named for a former president of the New England Power Company, the 3500 acre Moore Reservoir, where the river's waters back up behind the dam, is New Hampshire’s largest undeveloped lake, and the state's fourth largest lake overall.  The Moore Dam, along with the downstream Comerford and McIndoe dams, flooded out a river section formerly known as Fifteen Mile Falls.

The Moore Dam is just over twice as large as Maine's largest hydroelectric facility.  That honor falls to the 85 megawatt Harris Station facility on the upper Kennebec River, built in 1954 during the same era as the Moore Dam.
