Summary
Completed in 1967, this earth dam stands at a height of 28 feet and has a maximum storage capacity of 1,046 acre-feet. The dam, situated along TR-Sandy Creek, serves to protect the surrounding area from potential flooding events with a controlled spillway and one valve outlet gate.
With a low hazard potential and a very high risk assessment rating, SCS-Wildhorse Creek Site-118 remains a crucial infrastructure for managing water resources in the region. Despite not being rated for its condition, the dam is inspected every five years to ensure its structural integrity and functionality. The presence of regulatory agencies like OWRB and state permitting, inspection, and enforcement processes further highlight the importance of this dam in mitigating flood risks and protecting the local community from potential water-related disasters. For water resource and climate enthusiasts, this site serves as a significant example of sustainable water management practices and the critical role of infrastructure in adapting to 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.
