Summary
Constructed in 1999 by the USDA NRCS, this dam serves a variety of purposes and has a storage capacity of 39.3 acre-feet. With a height of 29.9 feet and a length of 275 feet, the dam covers a surface area of 2.8 acres and has a drainage area of 40 square miles.
Managed by the OWRB and regulated by the state of Oklahoma, Oknoname 22288 has a controlled spillway and a low hazard potential. Despite not being rated for its condition, the dam has a very high risk assessment level (1), highlighting the importance of continued inspections and risk management measures. With a single valve for outlet gates and a maximum discharge of 11.9 cubic feet per second, this dam plays a crucial role in water resource management in the region.
Water resource and climate enthusiasts will find Oknoname 22288 to be a fascinating structure due to its unique design and the challenges it faces in terms of risk assessment and management. As one of the many dams in the Tulsa District, this earth dam stands as a testament to the complex interplay between human infrastructure and natural forces, underscoring the need for careful monitoring and maintenance to ensure its continued effectiveness in water storage and flood control efforts.

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.
