Scs-Wildhorse Creek Site-078 Reservoir Report
Last Updated: December 16, 2025
SCS-Wildhorse Creek Site-078, located in Garvin, Oklahoma, is a state-regulated dam designed by the USDA NRCS in 1968 for the primary purpose of flood risk reduction along the TR-Five Mile Creek.

Summary
This earth dam stands at a height of 27 feet and has a storage capacity of 635 acre-feet, with a normal storage level of 91 acre-feet. The dam has a controlled spillway and a single valve outlet gate for water release.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Wildhorse Creek Site-078 indicates a very high risk level (1). The condition assessment for the dam is currently not rated, with the last inspection dating back to 1980. The dam is inspected every 5 years, with the emergency action plan and inundation maps status being unknown. With a risk management measures and guidelines status also unspecified, there may be areas of improvement needed for the safety and maintenance of this crucial flood control structure in the region.

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.
