Summary
Completed in 1960, this dam stands at a height of 25 feet and has a storage capacity of 135 acre-feet. With a controlled spillway and a low hazard potential, the dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last one conducted in May 2010.
Despite being classified as having a low hazard potential, Oknoname 123016 is considered to have a very high risk due to its proximity to populated areas. The dam has a valve outlet and a surface area of 7 acres, serving purposes other than flood control or water supply. While the dam's condition is currently not rated, it meets state permitting and inspection requirements, ensuring its structural integrity and public safety.
With its location in Pontotoc County, Oklahoma, Oknoname 123016 is part of the Tulsa District and is not owned or funded by any federal agency. The dam's design includes stone core and soil foundation, with a primary purpose that is classified as "Other." Despite its age, the dam continues to play a crucial role in managing water resources in the area, highlighting the importance of regular maintenance and risk assessment for infrastructure projects.

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.
