Summary
Constructed in 2000 by USDA NRCS, this dam primarily serves as a water supply source in the region. With a dam height of 22.2 feet and a hydraulic height of 11.75 feet, it has a storage capacity of 196 acre-feet and covers a surface area of 10.19 acres. The dam has a controlled spillway type and a low hazard potential rating.
Despite being rated as "Not Rated" in terms of condition assessment, Oknoname 30146 is deemed to have a very high risk potential, requiring attention to ensure its structural integrity and safety. It is situated within the Tulsa District and falls under the jurisdiction of the state of Oklahoma. The dam's purpose and design cater to water supply needs, with a drainage area of 983 square miles and a maximum discharge capacity of 29.6 cubic feet per second. Its risk management measures and emergency action plans are currently not specified, highlighting the importance of monitoring and maintenance for the long-term sustainability of this critical water infrastructure.

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.
