Summary
Completed in 1970, this dam stands at a height of 26 feet and has a storage capacity of 112 acre-feet. Situated on TR-Turkey Creek, this structure plays a crucial role in mitigating flood risks in the region, with a controlled spillway and a capacity to handle a maximum discharge of 256 cubic feet per second.
Managed by the OWRB and inspected every five years, SCS-Upper Washita Creek Site-103 boasts a low hazard potential and is deemed to be in a very high-risk area. With a single valve outlet gate, this dam has not been rated for its current condition but remains operational for flood control purposes. While its emergency action plan status and risk management measures are not specified, its strategic location and design make it a key asset in water resource management and climate resilience efforts in the area.
For water resource and climate enthusiasts, SCS-Upper Washita Creek Site-103 presents a fascinating case study of a state-regulated earth dam that serves a vital role in flood risk reduction in Roger Mills County, Oklahoma. With its historical significance dating back to 1970 and its impact on the surrounding watershed and community, this dam highlights the importance of infrastructure for water management and disaster preparedness. As efforts continue to assess and manage the risks associated with this structure, it remains a focal point for discussions on sustainable water resource management and climate adaptation strategies in the region.

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.
