The average daily flow at McAlpine is 118,000 cubic feet per second (3,340 m³/s). The lock chambers are located at the dam on the Kentucky side of the Ohio River and are capable of a normal lift of 37 feet (11 m) between the McAlpine pool upstream and the Cannelton pool downstream. The hydroelectric plant consists of eight turbine units with a net power generation capacity of 80,000 kilowatts. The hydroelectric plant is currently undergoing an 8-year long rehabilitation project. This will extend the life of the 1920s era turbine-generator units and increase power output to 100 megawatts. In October 2003, McAlpine was designated a Historic Civil Engineering Landmark by the American Society of Civil Engineers.
