Summary
Completed in 2004 by the USDA NRCS, this stone dam stands at a height of 24 feet and has a storage capacity of 116 acre-feet. The dam, located in Orlando, is designed to control the flow of the unnamed tributary of Stillwater Creek and covers a surface area of 7.9 acres. With a low hazard potential and a very high risk assessment rating, this dam is closely monitored by the Oklahoma Water Resources Board to ensure its safety and effectiveness.
Owned by the state and primarily used for fish and wildlife management, Oknoname 30121 plays a crucial role in supporting the local ecosystem. The dam's regulated status, frequent inspections, and enforcement measures by the OWRB reflect the state's commitment to water resource management and public safety. With a controlled spillway and a drainage area of 398 square miles, this dam is equipped to handle a maximum discharge of 132 cubic feet per second, reducing the risk of flooding and ensuring proper water flow in the area.
Despite its relatively low hazard potential, the risk assessment for Oknoname 30121 remains very high, indicating the importance of proactive risk management measures. With a designated emergency action plan (EAP) and regular inspections, this dam exemplifies the state's dedication to ensuring the safety and security of its water resources. As a significant structure in the Tulsa District, Oknoname 30121 stands as a testament to the careful planning and regulation that goes into managing water resources in Oklahoma.

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.
