Summary
Built in 1960, this dam stands at a height of 29 feet and has a storage capacity of 90 acre-feet. It serves as a vital structure on the TR Buffalo Creek, with a controlled spillway and a maximum discharge capacity of 5180 cubic feet per second. Despite its low hazard potential, Oknoname 059057 is classified as having a very high risk due to its age and condition assessment not being rated.
Managed by the Oklahoma Water Resources Board, this dam is subject to state regulations, inspections, and enforcement. It has a single valve outlet gate and is regularly inspected every five years, with the last inspection conducted in August 2011. The dam's primary purpose is listed as 'Other,' indicating its importance in water resource management and climate control in the region. Despite being privately owned, Oknoname 059057 plays a crucial role in flood control and water storage for the surrounding area, highlighting the importance of maintaining and monitoring such infrastructure for the safety and well-being of the community.

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.
