It is formed by the Old Hickory Lock and Dam (36°17′48″N 86°39′20″W / 36.29667°N 86.65556°W), located on the Cumberland River at mile 216.2 in Sumner and Davidson counties, approximately 25 miles (40 km) upstream from Nashville. The lock, dam, powerhouse and lake are operated and supervised by U.S. Army Corps of Engineers staff under the direction of the District Engineer at Nashville. Construction started in January 1952, and dam closure was completed in June 1954.
