Summary
Completed in 1965, this dam stands at a height of 55 feet with a hydraulic height of 50 feet, providing a storage capacity of 2038 acre-feet for flood control purposes. The dam has a spillway width of 1 foot and is equipped with a single valve outlet gate for water release.
Despite being assessed as in fair condition during the last inspection in September 2011, SCS-Rainy Mountain Creek Site-10 poses a high hazard potential due to its location and design. With a very high risk rating, there is a need for regular maintenance and risk management measures to ensure the dam's integrity and safety in the face of potential emergencies. The dam's emergency action plan status and risk assessment guidelines should be carefully monitored and updated to meet regulatory standards and protect downstream communities.
As water resource and climate enthusiasts, the unique features and risk profile of SCS-Rainy Mountain Creek Site-10 make it an intriguing case study for understanding the challenges and responsibilities associated with managing critical infrastructure in flood-prone areas. The collaboration between state and federal agencies, along with the continued monitoring of the dam's condition and emergency preparedness, highlights the importance of proactive measures in safeguarding water resources and mitigating potential disasters.

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.
