Summary
It sits along the TR-North Canadian River and is under state jurisdiction and regulation by the Oklahoma Water Resources Board.
The dam has a maximum storage capacity of 50 acre-feet and a normal storage capacity of 25 acre-feet. It features a controlled spillway and one outlet valve. Despite being classified as having a low hazard potential, it is considered to have a very high risk assessment rating of 1. The last inspection of the dam was conducted in August 2011, with a scheduled inspection frequency of every 5 years.
Overall, Oknoname 111065 serves as a critical infrastructure for water resource management in the region, providing flood control and storage capabilities. It is essential for climate enthusiasts and water resource professionals to monitor and maintain the dam to ensure its structural integrity and safety for surrounding communities and ecosystems. With its unique design and location along the North Canadian River, this dam plays a vital role in water management efforts in Oklahoma.

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.
