Summary
Built in 1940, this structure stands at a height of 30 feet and has a storage capacity of 270 acre-feet. With a low hazard potential and a very high risk assessment rating, this dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last one conducted in November 2001.
Despite its age, Oknoname 113126 remains in good condition and has a controlled spillway with a width of 1 foot. It serves a primary purpose classified as 'Other', and its design includes stone core and soil foundation materials. The dam's maximum discharge capacity is 700 cubic feet per second, making it an important structure for managing water resources in the area. While it is not associated with any federal agencies, it plays a crucial role in protecting the surrounding community from potential flooding events.
In the event of an emergency, Oknoname 113126 has one valve outlet gate for controlled water release. The dam is situated in Osage County, Oklahoma, under the jurisdiction of the state regulatory agency. With its strategic location and important role in water management, this dam represents a key asset for climate and water resource enthusiasts to monitor and study in the context of sustainable infrastructure development.

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.
