Summary
This earth dam stands at a height of 47 feet and spans a length of 1625 feet, providing a storage capacity of 2251 acre-feet. Despite lacking a spillway, the dam serves its primary purpose effectively, safeguarding the surrounding area from potential flooding events.
Managed by local government authorities and regulated by the Texas Commission on Environmental Quality (TCEQ), Upper Washita River WS SCS Site 11 Dam plays a vital role in maintaining the water resources in the region. With a drainage area of 9.24 square miles and a surface area of 29 acres, the dam serves as a critical infrastructure for flood control and water management. While its hazard potential is not available and its condition remains unrated, the dam's risk assessment indicates a high level of risk, highlighting the importance of ongoing monitoring and maintenance.
Although lacking certain regulatory and emergency preparedness features, Upper Washita River WS SCS Site 11 Dam remains a key component in the water resource infrastructure of Texas. With its significant storage capacity and historical significance in flood risk reduction, this dam stands as a testament to the importance of sustainable water management practices in the face of changing climate conditions and increasing water-related risks.

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.
