These structures were abandoned by NB Power four decades ago when they decommissioned a crumbling dam at Scott Falls on the West Branch Musquash River, allowing much of the reservoir behind it to drain away, but on the nearby East Branch Musquash, the dam infrastructure is largely intact.

NB Power decommissioned the Musquash Power station in 2009 when the last of its three antique 2.5 megawatt generators finally broke down.
