Summary
This impressive structure stands at a height of 42 feet with a hydraulic height of 36 feet and a structural height of 42 feet, providing a maximum storage capacity of 1260 acre-feet. With a normal storage capacity of 460 acre-feet and a spillway width of 2 feet, this dam plays a crucial role in managing water flow and mitigating flood risks in the region.
Despite its fair condition assessment and hazard potential rated as high, SCS-Beaver Creek Site-09 has undergone regular inspections and is equipped with a valve outlet gate for operational control. The dam's risk assessment deems it as having a very high risk level, emphasizing the importance of effective risk management measures. The dam's location within the Tulsa District and its association with the Natural Resources Conservation Service highlight the collaborative efforts involved in ensuring the safety and functionality of this vital water resource infrastructure.
Water resource and climate enthusiasts can appreciate the significance of SCS-Beaver Creek Site-09 as a key component in the flood risk reduction strategy for Custer County, Oklahoma. With a history of effective operation since its completion in 1967, this earth dam serves as a critical barrier against potential inundation events, demonstrating the importance of proactive infrastructure planning and maintenance in safeguarding communities and ecosystems against the impacts of extreme weather events and climate change.

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.
