Built in 1975 by the USDA NRCS, this earth dam stands at a height of 29 feet and stretches 1840 feet in length, offering a storage capacity of 2020 acre-feet for floodwaters. The dam's spillway, with a width of 162 feet, serves as an uncontrolled outlet to manage the peak discharge of 5053 cubic feet per second during heavy rainfall events.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Southeast Laterals WS SCS Site 8a-1 Dam has undergone recent inspections indicating an unsatisfactory condition assessment as of April 2021. With a moderate risk rating of 3, there is a need for enhanced risk management measures to ensure the dam's structural integrity and public safety. As water resource and climate enthusiasts, understanding the critical role of such infrastructure in mitigating flood risks and safeguarding communities underscores the importance of ongoing monitoring and maintenance efforts for sustainable water management in the region.
