Summary
Built in 1960, this Earth-type dam stands at 40 feet tall and spans 3310 feet in length, with a storage capacity of 50 acre-feet. While it has a low hazard potential, it is classified as having a very high risk due to its condition assessment being labeled as "Not Rated".
Managed by the Oklahoma Water Resources Board, Oknoname 111060 is equipped with a controlled spillway and a single valve outlet gate. Despite being last inspected in 2011, with a recommended inspection frequency of 5 years, the dam's emergency action plan readiness and risk management measures remain unspecified. The dam's risk assessment designation of "Very High (1)" underscores the importance of ongoing monitoring and maintenance efforts to ensure the safety and functionality of this vital water resource infrastructure.
With its strategic location in the Tulsa District and a proximity of 10 miles from STIDHAM, Oknoname 111060 serves as a critical component in the region's water management system. While currently in a state of disrepair, the dam's historical significance and potential impact on the surrounding environment underscore the need for continued regulatory oversight and investment in its rehabilitation and maintenance to mitigate potential risks and ensure long-term water resource sustainability for the community.

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.
