Summary
Completed in 1987, this structure stands at 18 feet in height and spans 665 feet in length, with a storage capacity of 270 acre-feet. Despite being categorized as having a low hazard potential, the risk assessment for this dam is rated very high, emphasizing the importance of ongoing monitoring and maintenance.
Owned by the state and regulated by the Oklahoma Water Resources Board, SCS-Wildhorse Creek Site-058 has a controlled spillway and is equipped with a single valve outlet gate. The dam's purpose is solely focused on flood risk reduction, serving an important role in managing water resources in the area. With a drainage area of 0.71 square miles and a maximum discharge capacity of 1105 cubic feet per second, this structure plays a crucial role in protecting the surrounding areas from potential flooding events.
The condition of SCS-Wildhorse Creek Site-058 is currently labeled as "Not Rated," with the last inspection conducted in 1980. Despite the lack of recent assessments, the dam's very high risk rating underscores the need for continued attention and adherence to safety guidelines. As water resource and climate enthusiasts, understanding and promoting the sustainable management of structures like SCS-Wildhorse Creek Site-058 is essential for safeguarding communities and ecosystems in the face of changing environmental conditions.

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.
