The Milltown Dam is a hydroelectric dam built on the St. Croix River between St. Stephen, New Brunswick, Canada and Calais, Maine, USA, and operated by NB Power. Its power house has a capacity of 4 megawatts with its 7 turbines. Built in 1881 and modernised in the early-1900s, it is the oldest hydroelectric dam in Canada, as well as the first hydroelectric facility built by NB Power.
