Markland Locks and Dam, Navigation locks and hydroelectric dam on the Ohio River between Kentucky and Indiana, United States.
Markland Locks and Dam is a navigation facility and hydroelectric structure on the Ohio River between Kentucky and Indiana. The complex allows large cargo vessels to move through the river by managing water level differences between upstream and downstream sections.
Construction started in 1956 with the locks opening in 1959, while the dam section took until 1964 to complete. This phased completion reflected the complexity of building such a major project on one of America's busiest shipping routes.
The facility represents a critical element in the Ohio River navigation system, supporting regional commerce and connecting communities across state borders.
The site is visible from the water and surrounding areas but offers limited public access points for viewing. Boaters passing through the locks get the closest view, while nearby bridges and shorelines provide distant vantage points.
The facility simultaneously generates hydroelectric power and supports millions of tons of cargo moving through annually. This dual function makes it essential infrastructure for economic activity across the entire region.
