Summary

Completed in 1962, this earth dam stands at a height of 49 feet and spans 2400 feet, with a storage capacity of 5843 acre-feet. The dam serves multiple purposes, including flood risk reduction and recreation, making it a valuable asset to the local community.

Managed by the TCEQ and with state regulatory oversight, the dam has not been rated for its condition assessment, but is considered to have a moderate risk level. The dam features an uncontrolled spillway and three outlet gates, with a maximum discharge capacity of 5711 cubic feet per second. While the hazard potential of the dam is not available, it is important to note that it plays a significant role in protecting the surrounding area from potential flooding events.

Overall, the Upper Washita River WS SCS Site 1 Dam is a well-maintained structure with a strategic location along the Washita River. Its construction and management reflect a commitment to flood risk reduction and safety for the community. As water resource and climate enthusiasts, it is important to recognize the importance of such infrastructure in mitigating the impacts of extreme weather events and ensuring the sustainable management of water resources in the region.

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.
