Summary
Standing at a height of 24 feet with a length of 450 feet, this dam serves as a crucial structure on TR BUFFALO CR. It has a storage capacity of 50 acre-feet and is equipped with a controlled spillway and a single valve outlet gate.
Despite being classified as low hazard potential, Oknoname 059047 is rated with a very high risk due to its aging infrastructure. The dam has not been inspected since August 2011, emphasizing the need for regular maintenance and assessment. While it is regulated by the Oklahoma Water Resources Board and falls under state jurisdiction, there are no federal agencies directly involved in its ownership or funding.
Water resource and climate enthusiasts should be aware of the significance of Oknoname 059047 in the local ecosystem and the potential risks it poses. With its condition not rated and lacking an emergency action plan, there is a pressing need for updated inspections, risk assessments, and management measures to ensure the safety and integrity of this essential water management structure.

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.
