Summary
Completed in 1949, this structure stands at a height of 17 feet and has a dam length of 1065 feet, holding a NID storage capacity of 248 acre-feet. The dam, situated on TR-Wildhorse Creek, is equipped with a controlled spillway and a single valve outlet gate.
Despite its low hazard potential, the risk assessment for SCS-Wildhorse Creek Site-001 indicates a very high risk level. The structure has not been rated for condition assessment, with the last inspection recorded in 1980. Emergency action preparedness details are not available, leaving room for improvement in terms of risk management measures. The site falls under the jurisdiction of the Oklahoma Water Resources Board and is subject to state permitting, inspection, and enforcement.
For water resource and climate enthusiasts, SCS-Wildhorse Creek Site-001 presents an intriguing case study of a decades-old flood control infrastructure in need of modern evaluation and maintenance. With a history dating back to the mid-20th century, this dam on Wildhorse Creek serves as a valuable asset for flood risk reduction in the region. However, the lack of recent inspections and updated emergency action plans highlight the importance of continuous monitoring and risk management practices for sustainable water resource management 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.
