This earth dam stands at a height of 40 feet and stretches 4020 feet in length, with a storage capacity of 4035 acre-feet. Despite being uncontrolled, the dam features two outlet gates for water release in case of emergency.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the dam is regularly inspected and meets state permitting requirements. With a moderate risk assessment rating, the dam's hazard potential is currently not available, and its condition assessment remains unrated. Although the dam's emergency action plan status is unknown, its risk management measures are not specified, indicating a need for further evaluation of potential risks and preparedness protocols in case of emergencies. For water resource and climate enthusiasts, the Upper Pecan Bayou WS SCS Site 18a Dam offers a fascinating case study in flood risk reduction infrastructure and the importance of effective dam management in ensuring public safety and environmental protection.
