Summary

Standing at a height of 25 feet with a length of 544 feet, this dam on the TR-Beaver River serves multiple purposes and has a storage capacity of 60 acre-feet. Despite its low hazard potential, the dam is classified as having a very high risk, which necessitates regular inspections and potential risk management measures.

Owned by a private entity, Barby No 18 falls under the regulatory jurisdiction of the Oklahoma Water Resources Board. The dam features a controlled spillway and one valve outlet gate, with a historical maximum discharge of 1720 cubic feet per second. While the dam's condition assessment is currently not rated, it undergoes inspections every five years to ensure its structural integrity and safety. Given its risk classification, it is crucial for stakeholders to have emergency action plans in place to mitigate any potential hazards associated with the dam.

Despite being privately owned, Barby No 18 plays a crucial role in water resource management in Beaver, Oklahoma. With a surface area of 10 acres and a drainage area that remains unspecified, the dam provides essential water storage for various purposes. As climate change continues to impact water resources, the effective management and regulation of dams like Barby No 18 are essential to ensure water security and resilience in the face of evolving environmental challenges.

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.
