Grapevine Dam, located in Carrollton, Texas, is a crucial structure owned and operated by the US Army Corps of Engineers to primarily reduce the risk of flooding in downstream communities along Denton Creek. Completed in 1952, the dam stands at 137 feet tall and spans 12,350 feet, with a storage capacity of 788,000 acre-feet. Despite its flood risk reduction benefits, a risk assessment in May 2019 classified the dam's hazards as moderate due to potential extreme storm events that could lead to significant downstream flooding, impacting communities from Grapevine to Dallas.
To manage these risks, the US Army Corps of Engineers implements various measures, including regular inspections, maintenance, and communication with local emergency managers. The Emergency Action Plan for Grapevine Dam is updated annually, and surveillance is increased as lake elevation rises. The Corps also collaborates with stakeholders to improve emergency response and coordination, ensuring the safety of downstream communities. Additionally, ongoing risk assessments and the implementation of interim risk reduction measures demonstrate the Corps' commitment to safeguarding the dam and surrounding areas from potential catastrophic flooding events.
