Summary
This earth dam, standing at a height of 29 feet and a length of 1290 feet, serves the primary purpose of mitigating flood risks along the TR-Wildhorse Creek. With a storage capacity of 428 acre-feet and a spillway width of 1 foot, the dam plays a crucial role in managing water flow and protecting the surrounding areas from potential inundation.
Managed by the Oklahoma Water Resources Board, the SCS-Wildhorse Creek Site-077 has a low hazard potential and a risk assessment rating of very high (1). Despite not being rated for condition assessment, the dam is reported to have undergone regular state inspections and enforcement measures. Although last inspected in 1980, the dam's emergency action plan status and risk management measures remain undisclosed. With a controlled spillway and a valve outlet gate, the SCS-Wildhorse Creek Site-077 stands as a vital infrastructure for water resource management in the region.
For water resource and climate enthusiasts, the SCS-Wildhorse Creek Site-077 presents an intriguing case study of a state-owned flood risk reduction structure in Oklahoma. With a historical significance dating back to 1967, this earth dam has been a crucial component in the state's water management and flood control efforts. Its location along the TR-Wildhorse Creek, coupled with its low hazard potential and high risk assessment rating, underscores the importance of maintaining and monitoring such critical infrastructure to ensure the safety and resilience of communities in the area.

Dam Data Reference
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.
