Summary
Built in 2000 by USDA NRCS, this earth dam stands at a height of 21.6 feet with a storage capacity of 115.45 acre-feet. The primary purpose of the dam is categorized as "Other", serving various functions within the local water resource management system.
Managed by the Oklahoma Water Resources Board, Oknoname 30080 is regulated, permitted, inspected, and enforced by state authorities. With a controlled spillway and low hazard potential, the dam poses minimal risk to the surrounding area. Despite being in operation for over two decades, the condition of the dam remains unrated as of the last inspection in 2010, highlighting the need for ongoing monitoring and assessment to ensure its structural integrity and safety.
With a very high risk assessment rating, Oknoname 30080 underscores the importance of proactive risk management measures to mitigate any potential hazards associated with the dam. Although not owned or funded by federal agencies, the dam plays a crucial role in water storage and management within the local ecosystem, emphasizing the need for continued collaboration between private owners and state regulators to uphold safety standards and protect water resources in the region.

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.
