Summary
Managed by the USDA NRCS, this recreational dam stands at a height of 20.7 feet with a hydraulic height of 17.3 feet. With a normal storage capacity of 40.94 acre-feet and a maximum discharge of 58.32 cubic feet per second, this dam serves as a vital water resource for the surrounding area.
Situated on a tributary to Sandy Creek, Oknoname 30237 is regulated by the Oklahoma Water Resources Board (OWRB) and is inspected, permitted, and enforced by state agencies. Despite its low hazard potential, the dam has a very high risk assessment due to its location and structural characteristics. With a drainage area of 0.26 square miles and a surface area of 5.34 acres, this dam plays a crucial role in water management and flood control in the region.
Although last inspected in June 2010, the dam's condition remains unrated. However, it is equipped with a controlled spillway and a single valve outlet gate for water release. With no associated structures and a risk management plan in place, Oknoname 30237 stands as a testament to responsible water infrastructure management in the face of changing climate patterns and increasing water resource demands.

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.
