Summary
Completed in 1960, this structure on TR Black Bear Creek stands at a height of 22 feet and has a storage capacity of 109 acre-feet. With a surface area of 7 acres and a spillway width of 1 foot, the dam plays a vital role in managing water flow and storage in the area.
The dam, with a low hazard potential and a very high risk assessment rating, is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections and enforcement to ensure its structural integrity and safety. The primary purpose of Oknoname 137074, classified as an Earth dam with stone core and soil foundation, is for other purposes related to water resource management. Despite not being rated for its condition assessment, the dam is equipped with a valve outlet gate and has a controlled spillway to manage excess water during periods of high discharge.
Located in Owens Prairie Cemetery, this dam on TR Black Bear Creek is a significant component of the water resource infrastructure in the area. With its strategic design and regulatory oversight, Oknoname 137074 plays a pivotal role in safeguarding water resources and managing the flow of water in Stephens County, 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.
