Summary
With a structural height of 41 feet and a length of 817 feet, this dam has a storage capacity of 382 acre-feet and serves a drainage area of 0.9 square miles. The dam features a controlled spillway and a single valve outlet gate for water management.
Despite being classified as low hazard potential, the risk assessment for SCS-Wildhorse Creek Site-060 is rated as very high (1), indicating the importance of regular inspections and maintenance. The dam has not been assessed for condition, emergency action plan preparedness, or inundation mapping, highlighting areas for improvement in risk management. With a risk management measures section that is currently blank, there is potential for enhancing safety protocols and emergency response procedures at this site to ensure the protection of surrounding communities and water resources.
In the event of a potential emergency, the lack of updated emergency contacts, EAP preparation, and adherence to guidelines raises concerns about the readiness and efficiency of response measures. With the site falling under the jurisdiction of the OWRB and state permitting, it is crucial for all stakeholders to collaborate on comprehensive risk assessment, management, and emergency response strategies to safeguard the integrity of SCS-Wildhorse Creek Site-060 and mitigate potential hazards related to its operation.

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.
