The dam was built in 1923 by the New England Power Company.[1] Some 215 feet high and 1250 feet long as its crest, it's one of the ten hydroelectric dams impounding the Deerfield River.[2] Owned and operated by Great River Hydro LLC it was purchased from the TransCanada Corporation in 2017.[3] The facility is an earthen dam with a relatively unusual concrete "Ben’s glory hole" (freestanding conical drain) spillway, similar to another example at Monticello Dam in California.

The reservoir it creates, Harriman Reservoir, has a water surface area of 2039 acres, a maximum depth of 180 feet, and has a gross storage capacity of 117,300 acre-feet.[2]

The name comes from utility executive Henry I. Harriman, president of the New England Power Company.
