The San Diego-Rosita Cks WS SCS Site 7 Dam, located in Duval County, Texas, along Tarancahuas Creek, was completed in 1964 by the USDA NRCS for the primary purpose of flood risk reduction.
This earth dam stands at a height of 35 feet with a length of 4020 feet, providing a maximum storage capacity of 9007 acre-feet and a normal storage capacity of 269 acre-feet. With a drainage area of 22 square miles and a surface area of 63 acres, the dam has a maximum discharge capacity of 14393 cubic feet per second.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the San Diego-Rosita Cks WS SCS Site 7 Dam is inspected every 5 years and was last assessed to be in fair condition in January 2018. The dam features an uncontrolled spillway with a width of 415 feet and is equipped with slide and uncontrolled outlet gates. While the hazard potential is not available, the risk assessment indicates a moderate risk level. Overall, this dam plays a crucial role in mitigating flood risks in the region and contributes to the sustainable management of water resources in the area.
