Summary
Standing at 20 feet high with a hydraulic height of 15 feet, this structure serves as a crucial flood control measure in Washita County. With a storage capacity of 99 acre-feet and a spillway width of 1 foot, Oknoname 149032 plays a significant role in managing water flow and protecting the surrounding area from potential inundation.
Managed by the Oklahoma Water Resources Board, this dam has a low hazard potential but is rated as very high in terms of risk assessment. Despite not being currently rated for its condition, Oknoname 149032 undergoes regular inspections every 5 years to ensure its structural integrity and operational efficiency. With a single valve outlet gate and a controlled spillway, this dam exemplifies sound engineering practices and effective flood management strategies, showcasing the importance of water resource infrastructure in mitigating natural disasters and safeguarding communities in vulnerable areas like Washita County.
As a vital component of the Tulsa District's flood risk reduction system, Oknoname 149032 stands as a testament to the collaborative efforts between private owners, state regulators, and federal agencies in safeguarding against potential water-related disasters. With its strategic location and effective design, this earth dam serves as a model for sustainable water resource management and climate resilience in Oklahoma, demonstrating the critical role of infrastructure in protecting lives and property from the impacts of extreme weather events and ensuring the long-term sustainability of water resources in the region.

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.
