Summary
Built in 1960, this earth dam stands at a height of 30 feet and has a total length of 910 feet, providing a storage capacity of 80 acre-feet for recreational purposes. The dam overlooks the TR-Skiatook Lake and is regulated by the Oklahoma Water Resources Board, ensuring that it meets state inspection and enforcement standards.
Despite being classified with an undetermined hazard potential and a lack of a condition assessment rating, Oknoname 113002 poses a very high risk according to the available data. With a controlled spillway and a single valve outlet gate, emergency action plans have not been prepared or updated for this dam. The risk management measures and inundation maps for the area remain unaddressed, indicating a need for further evaluation and potentially increased safety measures to mitigate any potential risks associated with the dam.
For water resource and climate enthusiasts, Oknoname 113002 presents an intriguing case study of a privately owned dam in Oklahoma with a mix of regulatory oversight and potential risks. The dam's location near TR-Skiatook Lake and its recreational purpose highlight the importance of balancing water management strategies with safety considerations. As discussions around dam safety and risk management continue, Oknoname 113002 serves as a reminder of the ongoing need for proactive measures to ensure the protection of both water resources and the surrounding communities.

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.
