Summary
Completed in 1977, this dam stands at a height of 51 feet with a hydraulic height of 45 feet and a length of 1500 feet. With a storage capacity of 4435 acre-feet and a maximum discharge of 16920 cubic feet per second, this dam plays a crucial role in managing water resources in the area.
The condition assessment of the SCS-Rainy Mountain Creek Site-31 is rated as fair, with a significant hazard potential and a very high risk assessment rating. The dam features a controlled spillway with a width of 2 feet and one valve outlet gate. Although last inspected in 2011, the dam is subject to regular inspections every three years to ensure its structural integrity and effectiveness in flood risk reduction. With its strategic location and design, the SCS-Rainy Mountain Creek Site-31 is a key component in the water resource management infrastructure of Kiowa County, Oklahoma.
Enthusiasts of water resources and climate will find the SCS-Rainy Mountain Creek Site-31 a fascinating example of engineering for flood risk reduction in a high-risk area. Managed by the Oklahoma Water Resources Board and with a state permit for operation, this dam showcases the importance of proactive water management in mitigating the impacts of extreme weather events. Its stone core and soil foundation contribute to its stability, while its significant storage capacity and controlled spillway enhance its ability to regulate water flow during periods of high discharge. As an essential piece of infrastructure in the Tulsa District, the SCS-Rainy Mountain Creek Site-31 stands as a testament to the ongoing efforts to safeguard communities and ecosystems from the effects of climate change.

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.
