Summary
Built in 1999 by USDA NRCS, this structure stands at a height of 24.6 meters and has a storage capacity of 67.13 acre-feet. With a normal storage capacity of 22.8 acre-feet and a surface area of 3.53 acres, this dam plays a crucial role in the management of water resources in the region.
Managed by the Oklahoma Water Resources Board, Oknoname 22282 is regulated, permitted, inspected, and enforced by the state authorities. The dam is classified as low hazard potential, but it has a very high risk assessment rating. Despite its risk level, the structure has not been rated for its condition and lacks an emergency action plan. With controlled spillways and a single valve outlet gate, this dam is an important part of the water infrastructure in the area.
Located on a tributary to Headquarters Creek in Lincoln County, Oklahoma, Oknoname 22282 falls under the jurisdiction of the Tulsa District of the US Army Corps of Engineers. While the dam has not been modified in recent years, it remains a key component in the local water management system. Climate and water resource enthusiasts will find this structure fascinating due to its design, purpose, and potential impact on the surrounding environment.

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.
