Joe Pool Dam, located in Dallas, Texas, was completed in 1986 by the US Army Corps of Engineers (USACE) with the primary purpose of flood risk reduction. The dam, standing at a height of 108 feet, has a storage capacity of 642,500 acre-feet and covers a surface area of 7,470 acres along Mountain Creek. While the dam reduces the risk of downstream flooding, there is a moderate level of risk associated with potential high-volume releases during extreme weather events.

To manage these risks, the USACE Fort Worth District works closely with local emergency managers to develop evacuation plans, conducts regular inspections and monitoring of the dam, and implements maintenance and repair measures as needed. The dam's performance is monitored through an instrumentation system, and risk reduction measures are continuously evaluated and implemented. Despite the efforts to mitigate risks, a remote event such as a dam breach could lead to significant flooding downstream, impacting communities like Grand Prairie, Irving, and Dallas. The USACE is committed to ongoing assessments and improvements to ensure the safety and integrity of Joe Pool Dam for the surrounding areas.
