Summary
The dam stands at 35 feet tall with a length of 100 feet, creating a reservoir with a normal storage capacity of 1500 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and is subject to regular inspections, with a low hazard potential and a very high risk assessment rating.
Situated on the TR-North Canadian River, Cohee offers a surface area of 80 acres for recreational activities such as fishing and boating. The dam features a controlled spillway with a width of 4 feet and is equipped with a single valve outlet gate. Despite its age, the dam has not been rated for its condition, but it meets regulatory guidelines and is operated in compliance with state permitting requirements.
Owned and maintained by a private entity, Cohee serves as a vital water resource for the surrounding community and contributes to the conservation of the local ecosystem. With its scenic location and diverse recreational opportunities, Cohee is a valuable asset in managing water resources and promoting climate resilience 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.
