The dam is located in Aroostook Junction, New Brunswick, immediately downstream of Fort Fairfield, Maine, and less than 1 km east of the Canada–United States border.
The Tinker Generating Station benefits from flow regulation upstream in Maine on Millinocket Lake and on the Aroostook River in Squa Pan.
There are also control facilities and a power house canal located on the Maine side of the border.
The Tinker Generating Station was constructed as a joint project of the New Brunswick Electric Power Commission and the Maine Public Service.
In 1999, the Maine Public Service sold its share of the plant to WPS Power Development, LLC of De Pere, Wisconsin.
