Summary
Completed in 1965, this earth dam stands at a height of 34 feet with a hydraulic height of 30 feet and a structural height of 34 feet. It has a length of 3,263 feet and a storage capacity of 757 acre-feet, serving its primary purpose effectively.
With a low hazard potential and a very high risk assessment rating, this dam remains a crucial structure for mitigating flood risks in the region. Equipped with a controlled spillway and one valve outlet gate, it has not undergone any modifications since its completion. Although its condition assessment is currently marked as "Not Rated," this dam's design and construction by the NRCS ensure its reliability and effectiveness in flood risk management for the community and the surrounding area.
Despite its last inspection date being in 1980, this dam continues to be actively regulated and inspected by the state agency OWRB, demonstrating a commitment to maintaining its safety and functionality. For water resource and climate enthusiasts, SCS-Rainy Mountain Creek Site-08a serves as a key example of infrastructure designed to address the challenges of managing water resources and mitigating flood risks in a high-risk area.

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.
