Summary
Built in 1950 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the TR-Wildhorse Creek. With a height of 33 feet and a length of 1170 feet, it provides a storage capacity of 554 acre-feet and has a surface area of 26 acres.
Managed by the OWRB, the SCS-Wildhorse Creek Site-033 has a controlled spillway and is equipped with a single valve outlet gate. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. Despite its age, the dam continues to play a crucial role in mitigating flood risks in the region, even though it has not been inspected since 1980. The risk assessment for this dam is marked as "Very High (1)," highlighting the importance of regular maintenance and upkeep to ensure its continued effectiveness in protecting the surrounding area from potential flooding events.

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.
