Summary
This Earth-type dam stands at a height of 20 feet and has a length of 1000 feet, with a storage capacity of 220 acre-feet. Despite being non-regulated by the state, the dam is equipped with state-permitted inspections and maintenance to ensure its structural integrity.
The dam, with a maximum storage capacity of 220 acre-feet and a normal storage of 108 acre-feet, plays a crucial role in supplying water to the surrounding area. Its lack of a spillway and high hazard potential indicate the importance of regular monitoring and risk management. The risk assessment for Matador Tank Dam is rated as high, highlighting the need for emergency action plans and preparedness to mitigate potential hazards.
While Matador Tank Dam may not have a designated federal agency overseeing its operations, the dam's significance in providing water supply to the region cannot be understated. As climate change continues to impact water resources, structures like Matador Tank Dam play a vital role in ensuring water security for communities in Texas. With its strategic location and critical function, the dam serves as a key asset in managing water resources and adapting to the changing climate conditions.

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.
