The dam features an uncontrolled spillway with a width of 83 feet and outlet gates that include a slide and two uncontrolled gates. Despite being in fair condition as of the last assessment in December 2017, the dam is inspected every five years to ensure its continued effectiveness in flood risk reduction. Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the East Fork Above Lavon WS SCS Site 31 Dam serves as a critical infrastructure piece in protecting the residents of Collin County from potential flooding events.
With a moderate risk assessment rating of 3, the dam is well-maintained and monitored to prevent any hazards or potential issues. While the hazard potential is not available, the structure meets regulatory guidelines and is equipped to handle emergency situations. As a key component of the Fort Worth District's water management system, this dam showcases the importance of sustainable water resource management and climate adaptation strategies in safeguarding communities from the impacts of extreme weather events.
