Summary
This 30-foot high structure on TR-Beaver Creek has a normal storage capacity of 30 acre-feet and a maximum storage of 360 acre-feet. It serves as a controlled spillway with a single valve outlet gate and has a low hazard potential, with a very high risk assessment rating. Despite not being rated for condition assessment, the dam is inspected every 5 years to ensure its structural integrity.
Managed by the Oklahoma Water Resources Board, Oknoname 113142 plays a crucial role in flood control and water management in the region. The dam has a hydraulic height of 25 feet and a structural height of 30 feet, with a length of 250 feet and a surface area of 5 acres. The dam's location in Frankfort, Oklahoma, makes it a vital infrastructure for protecting the surrounding area from potential flooding events. With state jurisdiction and regulatory oversight, the dam is subject to regular inspections, enforcement, and permitting to maintain its operational safety.
Despite its age, Oknoname 113142 continues to play a significant role in water resource management in Osage County. With a designated emergency action plan and updated contact information, the dam stands ready to respond to any potential risks. As an essential piece of infrastructure in the Tulsa District, this dam underscores the importance of proactive risk management and maintenance practices to ensure the safety and sustainability of water resources in the region.

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.
