Mountain Island Lake was built in 1924 with the construction of Mountain Island Hydroelectric Station. The lake has approximately 3,281 acres of surface area and 61 miles of shoreline. The lake also supports Riverbend Steam Station by cooling the steam that drives the turbines and provides a dependable water supply for Mount Holly, Gastonia and Charlotte-Mecklenburg, North Carolina.
Full pond elevation is approximately 647.5 feet.
Duke Power provides two boating access areas on the lake and a tailrace fishing platform for bank fishing in cooperation with the North Carolina Wildlife Resources Commission.
