Summary
With a height of 39 feet and a length of 1100 feet, this dam has a storage capacity of 360 acre-feet and a controlled spillway. Despite being rated as low hazard potential, this dam serves a critical role in mitigating flood risks in the area.
The dam's hydraulic and structural height both measure at 39 feet, with a normal storage capacity of 35 acre-feet and a maximum discharge of 1310 cubic feet per second. The dam is equipped with a single valve outlet gate for water release. While the condition assessment is marked as 'Not Rated' and the last inspection date dates back to 1980, the risk assessment categorizes the dam as having a very high risk level (1). Although lacking in recent inspection data and emergency action plans, the dam remains a vital infrastructure for flood control in the region.
Managed by the Natural Resources Conservation Service, SCS-Wildhorse Creek Site-046b stands as a testament to the ongoing efforts to regulate and maintain water resources in Oklahoma. With state jurisdiction and regulatory oversight from OWRB, this earth dam plays a crucial role in protecting the surrounding areas from potential flooding events. Despite its age, the dam continues to uphold its purpose of flood risk reduction, highlighting the importance of sustainable water resource management in the face of changing climate patterns.

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.
