Canada Falls Lake

Canada Falls Lake is impounded by an early 20th-century dam built on the South Branch Penobscot River upstream of its confluence with the North Branch Penobscot River. The lake created behind the dam in Pittston Academy Grant floods the South Branch Penobscot River westerly into Alder Brook Township and tributary Alder Brook southerly into Soldiertown Township. Most of the lake is less than deep. When full, Canada Falls Lake has the largest surface area of any lake on the South Branch Penobscot River; but the lake is usually drained by late summer, and remains low until filled by snowmelt the following spring.
