Summary
Completed in 1961, this structure stands at a height of 36 feet with a hydraulic height of 32 feet, and a total length of 1016 feet. With a storage capacity of 231 acre-feet, it serves as a critical infrastructure in mitigating flood hazards in the region.
The dam features a controlled spillway and a single valve outlet gate, with a hazard potential rated as low. Despite being constructed over six decades ago, the condition assessment is currently marked as "Not Rated" with the last inspection date recorded in 1980. While the risk assessment indicates a very high risk level, the dam remains an essential component of the flood risk reduction strategy in the area. It is noteworthy that the dam site is under the jurisdiction of the Oklahoma Water Resources Board (OWRB), ensuring state regulatory oversight for permitting, inspection, and enforcement.
Given the strategic location of SCS-Upper Washita Creek Site-056 in Cheyenne, Oklahoma, and its crucial role in managing flood risks along the Washita River, water resource and climate enthusiasts can appreciate the significance of this structure in safeguarding the surrounding communities and ecosystems. As efforts continue to enhance the resilience of water infrastructure in the face of changing climate patterns, ongoing monitoring and maintenance of this dam will be essential to ensure its effectiveness in flood mitigation and protection of downstream areas.

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.
