Larto Lake Dam in Catahoula, Louisiana, is a state-regulated structure managed by the Louisiana Department of Transportation and Development.
Completed in 1959, this earth dam stands at a height of 38 feet, with a primary purpose of providing recreation opportunities for visitors. Its location on Larto Bayou offers a scenic backdrop for outdoor enthusiasts looking to enjoy water activities in the area.
With a normal storage capacity of 15,000 acre-feet and a maximum storage of 126,000 acre-feet, Larto Lake Dam serves as a vital component of the local drainage area, covering 142 square miles. The dam's spillway type is uncontrolled, with a width of 60 feet, allowing for controlled release of excess water during high flow events. Despite its fair condition assessment and low hazard potential, regular inspections are conducted to ensure the dam's structural integrity and safety for the surrounding community.
Although the dam's risk assessment is considered moderate, with a DSAC assigned date pending, the overall risk management measures and emergency preparedness status are currently unspecified. As a popular spot for recreational activities and wildlife observation, Larto Lake Dam plays a significant role in enhancing the region's water resource management and climate resilience efforts.
