Summary
Built in 1967, this earth dam stands at a height of 30 feet and stretches 1100 feet in length, with a maximum storage capacity of 151 acre-feet. Despite being rated as having a low hazard potential, the dam's risk assessment is classified as very high, emphasizing the importance of effective risk management measures.
Managed by the Natural Resources Conservation Service, SCS-Wildhorse Creek Site-111 features a controlled spillway with a width of 1 foot and one valve outlet gate. While the dam's condition assessment is currently marked as not rated, it is subject to regular inspections every 5 years. The surrounding area boasts a surface area of 5 acres, providing essential flood risk reduction benefits to the community while aligning with the primary purpose of the dam's construction.
With a notable association with flood risk reduction efforts and a history dating back to the late 1960s, SCS-Wildhorse Creek Site-111 remains a critical piece of infrastructure in safeguarding the region against potential disasters. Its strategic location, state jurisdiction, and meticulous design by USDA NRCS underscore its significance in water resource management and climate resilience initiatives, making it a key site of interest for enthusiasts in the field.

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.
