Lock No. 3 is an abandoned lock and dam on Big Sandy River at Louisa, Kentucky, and Fort Gay, West Virginia.
Lock No. 3 on the Big Sandy River, located at Fort Gay, 26.2 miles upstream from the Ohio River, was completed in 1897. 1 It featured a 270-foot-long dam and was engineered to provide a 10.6-foot lift. The lock itself measured 158 feet in length and 52 feet in width.
Construction on this lock began in 1883 under the direction of Engineer B.F. Thomas. 2 The project faced several delays and cost overruns. In 1891, a significant alteration was made to the original plan, switching from a fixed dam to a moveable needle dam at Fort Gay, a first of its kind in the United States.
The total expenditure for Lock No. 3 reached $750,000 by its completion in 1897. 2 This achievement drew attention, including visits from engineers from Mississippi and Hungary and the Congressional River & Harbor Committee.
In 1902, the federal government approved a project to raise the height of the Fort Gay lock. 2 Despite this upgrade, transportation through the lock decreased significantly, from 300,000 tons to 194,000 tons.
The lock’s operations were reduced in 1920 due to ongoing repairs. 2 By 1922, traffic through the lock had dwindled with a minimal amount of coal and oil sent through. Locking operations were discontinued in 1947. 1 3
