The Lockington Locks are a group of canal locks
Lock (water transport)
A lock is a device for raising and lowering boats between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is...

. This small canal was designed to meet the main line at Lockington because the Summit included the canal's highest elevation of 944 feet (287.7 m) above sea level. As canal boats came north to Lockington, they were lifted by 67 feet (20.4 m): Lock 48, 10 feet (3 m); Lock 49, 11 feet (3.4 m); Lock 50, 11 feet (3.4 m); Lock 51, 11 feet (3.4 m); Lock 52, 12 feet (3.7 m); and Lock 53, 12 feet (3.7 m). Boats would typically take several hours to pass through the locks; as a result, the village of Lockington (originally named "Locksport") was founded to provide services to idle boatsmen and passengers. The individual locks at Lockington were constructed of large limestone

Later history

The most prosperous point in the history of Ohio's canal system was reached in 1855. After that year, revenues fell steadily because of competition from railroads; even small communities such as Lockington had train stations, and water sales became the canal's primary revenue stream. Restorations were attempted in the 1900s, but all attempts at refurbishing the system ended after a disastrous 1913 flood that destroyed many of the canal's components and ended all hopes of its future commercial use. Today, the Lockington Locks and the surrounding land are a park, and the only water that flows through the locks is runoff from heavy rains. The countryside surrounding the locks is scenic enough that the future may see the conversion of its towpath

, becoming the first location to receive this distinction either in Miami County or in Shelby County. Other canal-related sites in both counties were later added to the Register: the Piqua Historical Area State Memorial and the Twin Arch Stone Culvert in Miami County were listed in 1971 and 1978 respectively, and the Turtle Creek Culvert and Embankment in Shelby County was listed in 1978, although it was removed from the Register just seven years later. The locks qualified for inclusion on the Register both as an important engineering accomplishment and because of their place in the area's history: they were deemed to be significant both in Ohio's history
