Dewey Dam, also known as Dewey Lake, is a federal-owned structure located in Floyd County, Kentucky. Completed in 1949 by the US Army Corps of Engineers, this Earth-type dam serves multiple purposes including flood risk reduction, fish and wildlife habitat, and recreation. With a structural height of 118 feet and a hydraulic height of 86 feet, Dewey Dam helps to manage water levels on Johns Creek of Levisa Fork.

The dam has a storage capacity of 93,300 acre-feet and covers a surface area of 1,100 acres. Despite its high hazard potential, the USACE implements risk management measures, such as regular inspections, emergency action plans, and maintenance activities, to mitigate potential flood risks associated with the dam. By collaborating with local emergency managers and the public, the USACE ensures the safety and integrity of Dewey Dam for the surrounding community.

As a vital infrastructure for flood control and ecosystem preservation, Dewey Dam stands as a testament to the USACE's commitment to managing water resources effectively and safeguarding communities from potential risks. With ongoing monitoring and maintenance efforts, Dewey Dam continues to play a crucial role in water resource management in the region, demonstrating the importance of sustainable infrastructure development in the face of changing climate conditions.
