Summary
Standing at a height of 27 feet with a length of 422 feet, this dam has a storage capacity of 150 acre-feet and a maximum discharge of 1200 cubic feet per second. Despite its low hazard potential, it is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular state inspections, permitting, and enforcement to ensure its structural integrity and safety for nearby residents.
The dam features a controlled spillway and a single valve outlet gate for water management during flood events. Although it has not been rated for its condition assessment, it is considered to have a very high risk potential according to the risk assessment, emphasizing the importance of proper maintenance and emergency preparedness. The surrounding area, protected by this dam, benefits from the reduction of flood risks, highlighting the critical role of infrastructure like Oknoname 119009 in water resource management and climate resilience in the region.
In the event of an emergency, it is essential for stakeholders to have an updated emergency action plan (EAP) and clear communication channels with relevant authorities. While the dam has not had recent modifications or condition assessments, its risk management measures and potential hazard level indicate the need for proactive monitoring and maintenance to ensure its continued effectiveness in flood risk reduction. As water resource and climate enthusiasts, understanding the significance of dams like Oknoname 119009 in protecting communities and ecosystems underscores the importance of sustainable water infrastructure development and management practices in the face of changing climate conditions.

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.
