Summary

Completed in 1940, this earth dam stands at a height of 43 feet and serves primarily for recreational purposes, offering a storage capacity of 180 acre-feet. Despite being categorized as having a low hazard potential, it is regulated and inspected by the Oklahoma Water Resources Board to ensure its safety and compliance with state standards.

With a controlled spillway and a single valve outlet gate, Oknoname 037006 boasts a very high risk assessment rating, indicating the need for vigilant monitoring and management. Although its condition assessment is listed as "not rated," the dam's condition is regularly assessed through inspections, with the last one conducted in August 2011. While the dam's emergency action plan status and risk management measures are unspecified, its location within the Tulsa District of the US Army Corps of Engineers emphasizes the importance of maintaining its integrity and preparedness for potential emergencies.

Overall, Oknoname 037006 offers a glimpse into the intricate network of dams in Oklahoma, highlighting the crucial role they play in water resource management and recreation. As climate change continues to impact water availability and quality, ensuring the safety and resilience of structures like Oknoname 037006 becomes increasingly vital for sustainable water management and environmental protection in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
