Summary
Completed in 1964, this structure stands 33 feet tall with a hydraulic height of 30 feet and a length of 830 feet. It has a storage capacity of 225 acre-feet and a maximum discharge rate of 535 cubic feet per second.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Upper Washita Creek Site-064 indicates a very high risk level. The dam is equipped with a controlled spillway and a single outlet valve, with no associated locks. The last inspection was conducted in 1980, with a recommended inspection frequency of 5 years. The condition assessment is currently not rated, and there is limited information available on emergency action plans and risk management measures for this site.
Water resource and climate enthusiasts interested in the status of SCS-Upper Washita Creek Site-064 will find valuable information on its design, construction, storage capacity, and risk assessment. This structure plays a crucial role in flood risk reduction along the Washita River in Oklahoma, and its condition and maintenance are essential for ensuring public safety and environmental protection in the region. Further research and updates on inspection reports, emergency preparedness, and risk management strategies for this dam could provide valuable insights for stakeholders and researchers in the water resource management field.

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.
