Summary
Completed in 1970, this structure serves as a crucial component in managing water resources in the area, specifically along TR Black Bear Creek. With a dam height of 17 feet and a storage capacity of 51 acre-feet, it plays a key role in flood control and water storage for the region.
Although the dam is classified as low hazard potential, its risk assessment is rated as very high due to its condition not being rated and lack of updated emergency action plans. The dam features a controlled spillway and one outlet valve, with a maximum discharge capacity of 870 cubic feet per second. Despite being inspected every 5 years, the last assessment was conducted in September 2011, raising concerns about the current structural integrity and emergency preparedness of the dam.
As water resource and climate enthusiasts, it is imperative to monitor and assess the condition of dams like Oknoname 137079 to ensure the safety and efficiency of water management systems. With the risk potential being very high, there is a pressing need for updated inspections, maintenance, and emergency preparedness measures to mitigate any potential hazards and safeguard the surrounding community and environment from the impacts of dam failure.

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.
