This earth dam stands at a height of 31 feet and spans a length of 2900 feet, with a maximum storage capacity of 8716 acre-feet and a normal storage capacity of 200 acre-feet. Despite being uncontrolled, the dam has two outlet gates to manage water flow and prevent potential flooding in the area.
Managed by the Natural Resources Conservation Service, the dam is regulated by the Texas Commission on Environmental Quality and undergoes regular inspections, with the most recent assessment in 2018 rating the dam's condition as fair. With a moderate risk assessment and a hazard potential not available, the dam serves as a critical infrastructure to protect the surrounding area from flood events and ensure water resource management in the region. The site is under the jurisdiction of the state and federal agencies, with a focus on maintaining safety and operational efficiency for the community of San Diego.
