Built in 1953 by the Louisiana Department of Public Works, this earth dam stands at a height of 18 feet and stretches 2500 feet in length, creating a surface area of 3028 acres and a normal storage capacity of 11,500 acre-feet. The dam regulates the flow of the Samson Channel, with a maximum discharge capability of 40,500 cubic feet per second.
Despite its crucial role in water management and recreation, Smithport Lake Dam faces challenges in terms of its condition assessment, with a poor rating as of May 2017. The dam's hazard potential is classified as low, but its risk assessment is moderate, highlighting the need for ongoing monitoring and maintenance. The Louisiana Department of Transportation and Development oversees the regulatory aspects of the dam, including permitting, inspection, and enforcement, to ensure public safety and environmental protection.
As a hub for outdoor activities and water sports, Smithport Lake Dam remains a popular destination for visitors seeking leisure and relaxation. With its scenic surroundings and ample storage capacity, the dam continues to be a valuable asset for the local community. Efforts to address its maintenance needs and mitigate potential risks will be crucial in sustaining the dam's role in water resource management and climate resilience for years to come.
