Summary
Completed in 1968, this earth dam stands at 28 feet high and spans 1950 feet, providing a storage capacity of 1056 acre-feet. With a spillway width of 1 foot and a maximum discharge of 3935 cubic feet per second, this dam plays a crucial role in managing flood risk in the area.
Despite being in fair condition according to the last inspection in 2011, SCS-Upper Red Rock Creek Site-18 has a significant hazard potential, with a very high risk assessment rating. The dam is equipped with a single valve outlet gate and is regularly inspected by the state regulatory agency, OWRB. It is important for water resource and climate enthusiasts to monitor the condition and risk level of this dam to ensure the safety and effectiveness of its flood risk reduction capabilities in the future.
Overall, SCS-Upper Red Rock Creek Site-18 serves as a vital infrastructure for flood risk management in the region, with a history of successful operation since its completion over five decades ago. As water resource and climate enthusiasts continue to study and advocate for sustainable water management practices, this dam stands as a key example of collaboration between state agencies and federal designers to protect communities and ecosystems from the impacts of extreme weather events.

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.
