Summary
Built in 1964 by USDA NRCS, this earth dam stands at a height of 35 feet and has a hydraulic height of 32 feet. With a maximum storage capacity of 318 acre-feet and a normal storage of 93 acre-feet, this dam plays a crucial role in managing water flow along TR-Beaver Creek.
The dam's low hazard potential, controlled spillway type, and valve outlet gate highlight its efficient design for flood control. Despite not having a recent condition assessment, SCS-Beaver Creek Site-09a is classified as having a very high risk (1) due to its critical function in managing water levels in the area. With state oversight from OWRB and regular inspections, this dam serves as a vital infrastructure for water resource management in Custer County, Oklahoma.
Enthusiasts of water resources and climate will appreciate the strategic location and design details of SCS-Beaver Creek Site-09a. Its historical significance, state regulation, and high-risk classification underscore the importance of this dam in safeguarding the local community against flooding events. As a key structure in the Tulsa District, this earth dam stands as a testament to effective flood risk reduction measures implemented by the Natural Resources Conservation Service.

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.
