Summary
This earth dam, with a height of 28 feet and a length of 320 feet, was completed in 1950 and serves the primary purpose of "Other." The dam has a storage capacity of 50 acre-feet and a normal storage level of 25 acre-feet. It is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, with the last one conducted in November 2001.
Despite its low hazard potential, the dam at Oknoname 113062 poses a very high risk due to its condition assessment being "Not Rated." The spillway is of the controlled type with a width of 1 foot, and it has one outlet gate in place. The risk management measures, emergency action plan (EAP) preparation, and inundation maps are currently not specified. The dam falls under the jurisdiction of the Tulsa District of the US Army Corps of Engineers and is located on the TR-Sunset Creek, with maximum discharge capacity of 1736 cubic feet per second.
Overall, Oknoname 113062 serves as a significant water resource in Osage County, Oklahoma, with its vital role in flood control and water storage. Climate and water resource enthusiasts will find this dam's history, design features, and risk assessment to be of interest, as it provides valuable insights into the management and regulation of dams in the region. The data on this dam highlights the importance of regular inspections, risk assessments, and emergency preparedness in ensuring the safety and reliability of water infrastructure in the face of changing environmental conditions.

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.
