Summary
Built in 1964 for the primary purpose of flood risk reduction, this dam stands at a height of 25 feet and has a storage capacity of 132 acre-feet. It has a controlled spillway type with a width of 1 foot and is equipped with a single valve outlet gate.
Despite being classified as having a low hazard potential, Oknoname 149043 is considered to have a very high risk due to its condition being rated as "Not Rated". The last inspection on record dates back to August 2006, with an inspection frequency of 5 years. It is regulated and inspected by the Oklahoma Water Resources Board (OWRB), ensuring that the dam complies with state regulations and safety standards. The dam is situated within the Tulsa District and falls under the jurisdiction of the state of Oklahoma.
With its strategic location and crucial role in flood risk reduction, Oknoname 149043 serves as a vital infrastructure for water resource management in the Washita County area. Climate and water resource enthusiasts will find this dam's design and operational details intriguing, as it highlights the intersection of human engineering and environmental protection in mitigating potential risks and safeguarding communities from flood hazards.

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.
