Summary
This dam stands at a height of 26 feet and spans 1550 feet, with a storage capacity of 447 acre-feet and a spillway width of 1 foot. Despite being classified as having a high hazard potential, the dam is currently in fair condition and is inspected annually by the Oklahoma Water Resources Board to ensure its structural integrity.
The dam, managed by the state agency OWRB, serves as a vital flood control structure in the area and plays a crucial role in protecting the surrounding community from potential inundation during heavy rainfall events. With a maximum discharge capacity of 1355 cubic feet per second, the dam's controlled spillway and valve outlet gate provide effective mechanisms for managing water levels and reducing the risk of downstream flooding. The dam's risk assessment indicates a very high risk level, emphasizing the importance of ongoing monitoring and maintenance to uphold its safety and functionality.
Overall, SCS-Wildhorse Creek Site-057 represents a significant infrastructure project aimed at safeguarding the local area from flood hazards and ensuring water resource management in a critical watershed. With its strategic location and purposeful design, this dam exemplifies the intersection of engineering innovation and environmental stewardship in addressing the challenges of climate variability and water conservation in Oklahoma.

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.
