Summary

Standing at 35 feet high and 1290 feet long, this dam has a storage capacity of 768 acre-feet and serves its primary purpose effectively. Despite being rated as having a low hazard potential, the risk assessment for this dam is classified as very high, emphasizing the importance of regular inspections and maintenance.

The dam features a controlled spillway with a width of 2 feet and an outlet gate in the form of a valve. While the condition assessment is currently listed as "Not Rated" and the last inspection dates back to 1980, the dam is still operational and monitored by the OWRB. With its stone core and soil foundation, the SCS-Wildhorse Creek Site-041 remains a crucial structure in managing water resources and mitigating flood risks in the region.

As climate change continues to impact water resources and infrastructure, the SCS-Wildhorse Creek Site-041 serves as a vital component in the resilience of the local community to extreme weather events. With its strategic location and design specifications, this dam plays a significant role in protecting downstream areas from potential flooding, highlighting the importance of ongoing regulatory oversight and maintenance to ensure its continued effectiveness in the face of evolving climate challenges.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
