Summary

Constructed in 1960, this dam stands at a height of 20 feet and has a capacity for storing 140 acre-feet of water, with a normal storage level of 70 acre-feet. The primary purpose of this dam is for recreation, offering a surface area of 12 acres for various water activities.

Managed and regulated by the Oklahoma Water Resources Board (OWRB), Oknoname 027017 has a controlled spillway with a width of 1 foot. Despite being classified as having a low hazard potential, the risk assessment for this dam is ranked as very high. This highlights the importance of regular inspections, with the last one conducted in February 2001 and scheduled every 5 years. Emergency action plans and risk management measures for this dam are currently not rated or documented.

With its scenic location in Cleveland County and close proximity to the Tulsa District, Oknoname 027017 serves as a vital recreational spot for the local community. As water resource and climate enthusiasts, it is essential to monitor and uphold the safety standards of this dam to ensure the protection of both the environment and public well-being.

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.
