Summary
Built in 1960, this dam stands at a height of 25 feet and has a maximum storage capacity of 83 acre-feet. It serves as a vital structure for controlling the flow of the TR Black Bear Creek, with a controlled spillway and a single valve outlet gate.
Managed by the Oklahoma Water Resources Board, Oknoname 137082 has been designated as a low hazard potential structure with a very high risk assessment rating. While it is not currently rated in terms of condition assessment, it undergoes inspections every 5 years to ensure its structural integrity and safety. Despite its relatively low hazard potential, the dam's risk assessment rating highlights the importance of ongoing monitoring and maintenance to prevent any potential risks to the surrounding area.
With a history of state regulation and enforcement, Oknoname 137082 plays a crucial role in water resource management in the area. Its presence not only aids in flood control but also provides stored water for various purposes. As climate change continues to impact water resources, structures like Oknoname 137082 become even more essential for ensuring the sustainable use and management of water in Oklahoma.

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.
