Hardy Dam

Hardy Dam (or Hardy Hydroelectric Plant) is a dam and powerplant complex on the Muskegon River in Big Prairie Township, Newaygo County, Michigan. At the time of its completion, it was the largest earthen dam in North America east of the Mississippi, and is still the third largest earthen dam in the world and the largest east of the Mississippi River. Its impoundment forms a lake with over 50 miles of shoreline. The dam impounds a reservoir of 4,000 acres (1,618 ha) and is capable of producing 30,000 kilowatts of electricity.
