Summary
Completed in 1940, this dam stands at a height of 30 feet and has a storage capacity of 120 acre-feet. Despite its low hazard potential, it is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, as well as state enforcement and permitting.
Managed by the Tulsa District of the US Army Corps of Engineers, Oknoname 111049 has a controlled spillway and a single valve outlet gate. The dam's condition is currently not rated, but it poses a very high risk due to its age and potential impact on the surrounding area in the event of a failure. While it lacks certain emergency preparedness measures, such as an Emergency Action Plan, its risk management strategies are not specified in the available data.
Overall, Oknoname 111049 serves as a vital structure in the region's water resource management, highlighting the importance of monitoring and maintaining aging infrastructure to ensure the safety and sustainability of water resources in Oklahoma. Climate and water resource enthusiasts would find this dam's design and regulatory details significant in understanding the complexities of managing water infrastructure in the face of evolving environmental challenges.

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.
