Joe Pool Dam Reservoir Report

Last Updated: December 5, 2025

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.

Summary

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.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
