Summary
Built in 1960, this dam stands at a height of 22 feet and has a storage capacity of 87 acre-feet. With a normal storage capacity of 71 acre-feet, this dam serves multiple purposes beyond flood control, making it a valuable water resource in the region.
Managed by the Oklahoma Water Resources Board, Oknoname 141004 is inspected every five years and has a low hazard potential. Despite being classified as "Not Rated" in terms of its condition assessment, this dam is considered to have a very high risk level, emphasizing the importance of proper risk management measures. Equipped with a controlled spillway and a single valve outlet gate, this dam plays a crucial role in water management and conservation efforts in Tillman County.
Although the dam's condition assessment is not rated, its very high risk level underscores the need for proactive risk management strategies. As a vital water resource in the region, Oknoname 141004 serves as a testament to the intricate balance between water resource management and climate resilience. With the potential to enhance its emergency action plan and risk assessment guidelines, this dam stands as a key player in safeguarding water resources for the future.

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.
