Summary
Completed in 1973, this earth dam stands at a height of 30 feet and has a hydraulic height of 26 feet, providing a maximum storage capacity of 308 acre-feet. The dam is situated on TR-Elk Creek in Washita County and falls under the jurisdiction of the Oklahoma Water Resources Board.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Upper Elk Creek Site-14 indicates a very high risk level, possibly due to its age and limited condition assessment information available. With only one valve outlet gate and a controlled spillway, the dam is inspected every five years, with the last inspection dating back to 1980. It is crucial for water resource and climate enthusiasts to monitor this dam closely, given its critical role in flood control in the region and the high risk associated with its current condition.
As the risk management measures, emergency action plan, and inundation maps for SCS-Upper Elk Creek Site-14 are not readily available, there is a pressing need for updated information and preparedness protocols to be established. With the potential for high consequences in the event of a dam failure, it is imperative that regulatory agencies and stakeholders work together to ensure the safety and resilience of this vital water resource infrastructure in Oklahoma.

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.
