Summary
Completed in 1960, the dam stands at a height of 22 feet and has a storage capacity of 155 acre-feet, primarily serving the purpose of flood risk reduction along the TR-Council Creek. The dam has a controlled spillway, one outlet gate, and is classified as low hazard potential with a very high risk assessment rating.
Managed by the Oklahoma Water Resources Board, Oknoname 119010 has state-regulated permitting, inspection, and enforcement processes in place to ensure its structural integrity and public safety. The dam underwent its last inspection in December 2003, with an inspection frequency of every 5 years. Despite not being condition-rated, the dam's risk management measures are yet to be specified, highlighting the need for further assessment to mitigate potential risks associated with its operations.
Located within the Tulsa District of the US Army Corps of Engineers, Oknoname 119010 serves as a key infrastructure for flood control in the region, with a history of modifications and updates to meet evolving safety standards. As a vital component of water resource management in Oklahoma, the dam's significance lies in its ability to protect downstream communities from potential flooding events while maintaining a balance between environmental conservation and public safety.

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.
