Alcona Dam is a hydroelectric facility situated on the Au Sable River in Michigan, capable of producing 8 MW of electricity. Initially called Bamfield Dam, after an adjacent roadway, its construction commenced in 1917 but encountered delays due to shifting sand conditions and the impact of World War I. Construction activities recommenced in 1923, leading to the start of commercial power generation by Alcona Hydro in 1924. The dam harnesses an elevation difference of around 30 ft, which fluctuates throughout the year.
