Summary
Built in 1965 on TR-West Beaver Creek, this dam stands at a height of 25 feet and has a length of 380 feet, providing a storage capacity of 60 acre-feet. With a spillway width of 1 foot and a controlled spillway type, the dam has a hazard potential rated as low and a very high risk assessment score of 1.
Managed by the Oklahoma Water Resources Board (OWRB), Oknoname 083040 is regularly inspected and regulated by the state agency. Despite not being rated for its condition assessment, the dam's emergency action plan (EAP) status remains undisclosed. With a maximum discharge capacity of 6400 cubic feet per second, this dam serves a primary purpose classified as "Other." The surrounding area covers a surface area of 4 acres and has a normal storage capacity of 40 acre-feet.
With its location in Logan County, Oklahoma, Oknoname 083040 contributes to the local water resource management and climate resilience efforts. While the dam's risk management measures and emergency preparedness status are not specified, its presence on TR-West Beaver Creek serves as a key infrastructure for flood control and water storage in the region. As a part of the Tulsa District, this dam plays a crucial role in ensuring the safety and sustainability of the water supply in the area.

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.
