Summary

Completed in 1961, this dam stands at a height of 42 feet and has a hydraulic height of 38 feet, with a total length of 1640 feet. With a storage capacity of 1591 acre-feet and a normal storage level of 665 acre-feet, this dam plays a crucial role in mitigating flood risks in the area.

Despite being classified as a low hazard potential structure, the risk assessment for SCS-Upper Washita Creek Site-039 indicates a very high risk level. The dam features a controlled spillway with a width of 2 feet and an outlet gate equipped with a valve. Although the condition assessment is not rated and the last inspection was conducted in 1980, the dam is still actively regulated and inspected by the Oklahoma Water Resources Board for compliance and safety measures.

For water resource and climate enthusiasts, SCS-Upper Washita Creek Site-039 serves as a fascinating example of infrastructure designed to manage flood risks and protect communities in the region. The presence of this earth dam on Turkey Creek highlights the importance of proactive measures in water management and the ongoing efforts to ensure the safety and functionality of such critical structures. As discussions around climate resilience and sustainable water resource management continue to evolve, sites like SCS-Upper Washita Creek Site-039 provide valuable insights into the intersection of infrastructure, regulation, and environmental stewardship.

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.
