Summary
Built in 1964, this earth dam stands at a height of 39 feet and stretches 210 feet in length. It serves primarily for recreational purposes, with a storage capacity of 50 acre-feet and a surface area of 4 acres. The dam is regulated by the Oklahoma Water Resources Board and is subject to regular state inspection and enforcement to ensure its safety.
Situated on a tributary of Deer Creek, Oknoname 039003 has a controlled spillway and a low hazard potential, making it a relatively safe structure. Despite being rated as "Very High (1)" in terms of risk assessment, the dam's condition is currently not rated, with its last inspection conducted in June 2011. Emergency action plans and inundation maps for the dam have not been prepared or updated, suggesting a potential area for improvement in terms of risk management measures. The dam is not operated by the U.S. Army Corps of Engineers, further highlighting the responsibility of its private owner to ensure its safety and compliance with state regulations.

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.
