Summary
With a structural height of 16 feet and a length of 610 feet, this dam serves multiple purposes and has a normal storage capacity of 20 acre-feet. Despite being classified as low hazard potential, it is subject to regular state regulation, inspection, and enforcement by the Oklahoma Water Resources Board.
The dam features a controlled spillway with a width of 1 foot and outlet gates consisting of a single valve. While the risk assessment for Oknoname 063015 indicates a very high risk level, it has not been rated for its condition. The last inspection was conducted in August 2011, with an inspection frequency of 5 years. The dam's emergency action plan status, inundation maps, and risk management measures are currently unspecified.
Overall, Oknoname 063015 presents an intriguing case study for water resource and climate enthusiasts, showcasing the intersection of private ownership, state regulation, and risk management in dam infrastructure. With its historical significance, unique design features, and ongoing oversight by the OWRB, this dam serves as a noteworthy example of the complexities involved in managing water resources and mitigating potential hazards in the face of changing environmental conditions.

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.
