Summary
Standing at 25 feet tall and 500 feet long, this dam plays a crucial role in protecting the surrounding area from potential flooding events. With a maximum storage capacity of 120 acre-feet and a controlled spillway, Oknoname 037073 is designed to manage high discharges of up to 3400 cubic feet per second, ensuring the safety of the community.
Although classified as having a low hazard potential, Oknoname 037073 is considered to have a very high risk due to its location and the surrounding infrastructure. Despite its age, the dam has not been rated for its condition, highlighting the need for regular inspections and maintenance. With a single valve outlet gate and no associated structures, the dam relies solely on its design and construction integrity to function effectively in times of need. The risk management measures for Oknoname 037073 remain unspecified, leaving room for improvement in safeguarding this important flood control structure.
As a key element in the flood risk reduction strategy for the area, Oknoname 037073 serves as a vital asset in protecting the community from potential disasters. With its state-regulated status and the involvement of the Oklahoma Water Resources Board, the dam is subject to regular inspections and enforcement measures to ensure its continued safety and effectiveness. However, the lack of detailed risk management measures and updated emergency preparedness plans raise concerns about the long-term resilience of this essential water resource infrastructure in the face of evolving climate challenges.

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.
