Summary
With a dam height of 40 feet and a hydraulic height of 37 feet, this earth dam serves its purpose effectively with a storage capacity of 278 acre-feet. The dam, constructed with stone core and soil foundation, spans 1020 feet in length and has a controlled spillway with a width of 1 foot.
Despite being classified as having a low hazard potential, SCS-Wildhorse Creek Site-108 is considered to have a very high risk level due to its location and design characteristics. The dam is inspected every 5 years, with the last inspection reported in January 1980. While the condition assessment is currently not rated, the dam is equipped with a valve outlet gate for operational control. Although the Emergency Action Plan (EAP) status is unknown, the dam's risk management measures and inundation maps preparedness are not specified in the available data.
Overall, SCS-Wildhorse Creek Site-108 stands as a vital infrastructure for flood risk reduction in the area, safeguarding the surrounding community from potential inundation events. With its historical significance dating back to the 1970s, the dam's structural integrity and maintenance are crucial for ensuring its continued effectiveness in protecting the region's water resources and environment.

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.
