Summary
Constructed in 1955, this dam stands at a height of 20 feet and has a storage capacity of 75 acre-feet. The dam's spillway type is 'Controlled' with a spillway width of 1 foot, and it is regulated by the Oklahoma Water Resources Board.
Despite being rated as having a low hazard potential, Oknoname 049016 is associated with a very high risk assessment, scoring a '1' on the risk scale. The dam has not been assigned a Dam Safety Action Classification (DSAC) date, and its current condition has not been rated. The dam's last inspection took place on May 3, 2010, with an inspection frequency of 5 years. Emergency action plans (EAP) for this dam have not been prepared, and there is limited information available on its risk management measures.
For water resource and climate enthusiasts, Oknoname 049016 presents an intriguing case study of a privately owned earth dam with a complex risk assessment profile. With its unique design features and regulatory oversight by the OWRB, this dam serves as a focal point for understanding the intersection of infrastructure management and environmental stewardship in the state of Oklahoma. Further research and monitoring of this dam could provide valuable insights into enhancing dam safety protocols and mitigating potential risks associated with its operation.

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.
