The McAlpine Locks and Dam are a set of locks and a hydroelectric dam at the Falls of the Ohio River at Louisville, Kentucky. They are located at mile point 606.8, and control a 72.9 miles (117.3 km) long navigation pool. The locks and their associated canal were the first major engineering project on the Ohio River, completed in 1830 as the Louisville and Portland Canal, designed to allow shipping traffic to navigate through the Falls of the Ohio.
