Summary

Completed in 1969, this dam stands at 26 feet tall with a hydraulic height of 22 feet and a length of 6840 feet, providing a maximum storage capacity of 625 acre-feet and normal storage of 158 acre-feet. The controlled spillway with a width of 1 foot ensures the safe discharge of water during high-flow events.

Despite being categorized as having a low hazard potential, the risk assessment for SCS-Rainy Mountain Creek Site-35 indicates a very high risk level, requiring ongoing monitoring and potential risk management measures. The dam is equipped with a single valve outlet gate for water release, and while it has not been inspected since 1980, it is rated as "Not Rated" in terms of condition assessment. With the Oklahoma Water Resources Board as the state regulatory agency overseeing permitting, inspection, and enforcement, SCS-Rainy Mountain Creek Site-35 plays a crucial role in managing water resources and mitigating flood risks in the Kiowa County area.

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.
