Summary
Built in 1960, this earth dam stands at a height of 30 feet and has a storage capacity of 110 acre-feet. The primary purpose of this structure, situated on TR-Bear Creek, is categorized as "Other," with a spillway type identified as "Controlled." The dam's hazard potential is rated as low, but it carries a very high risk assessment score of 1, indicating the need for careful monitoring and management.
Although Oknoname 087040 is not under the jurisdiction of the federal government, it is regulated by the Oklahoma Water Resources Board (OWRB) and subject to state permitting, inspection, and enforcement. The dam features a single valve outlet gate and has a surface area of 4 acres, serving the surrounding area with a normal storage capacity of 47 acre-feet. Despite its relatively modest size, the dam's risk assessment highlights the importance of maintaining infrastructure integrity and emergency preparedness measures.
With a history of state regulatory oversight and periodic inspections, Oknoname 087040 exemplifies the critical role that privately owned dams play in managing water resources and mitigating potential hazards. As an integral component of the local watershed system, this dam on TR-Bear Creek underscores the need for ongoing monitoring and risk management to ensure the safety and sustainability of water infrastructure 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.
