Summary
The earth dam, with a height of 14 feet and a length of 1140 feet, holds a maximum storage capacity of 475 acre-feet. While the dam is primarily used for water supply, it also plays a role in flood control along the TR-Nueces River.
Despite its age, Mustang Tank Dam has not been rated for its condition, and its hazard potential is currently not available. The risk assessment for the dam is noted as high, signaling a need for continued monitoring and maintenance to ensure its structural integrity and safety. While the dam lacks a spillway, it features an outlet gate for water release. The dam's location within the Fort Worth District highlights its importance in water resource management and climate resilience efforts in the region.
As water resource and climate enthusiasts, the Mustang Tank Dam represents a critical infrastructure piece in Texas, providing essential water supply for local communities. With its high-risk assessment, there is a clear need for ongoing monitoring and risk management measures to safeguard the dam's functionality and prevent potential hazards. This earth dam stands as a testament to the importance of sustainable water management practices in the face of changing climate conditions, highlighting the need for proactive measures to ensure water security in the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
