Summary

Completed in 1970, this earth dam stands at a height of 25 feet and has a storage capacity of 247 acre-feet. With a surface area of 28 acres, the dam serves as a vital water resource for the surrounding area, providing water for irrigation and agricultural purposes.

Managed by the Oklahoma Water Resources Board, Oknoname 013001 has been regulated, inspected, and enforced to ensure its safety and functionality. Despite being rated as having a low hazard potential, the dam is classified as having a very high risk assessment due to its critical importance in water resource management. With a controlled spillway and one outlet valve, the dam is equipped to handle a maximum discharge of 930 cubic feet per second, ensuring efficient water management during periods of high flow.

Although not rated for its condition assessment, Oknoname 013001 remains a crucial infrastructure for water supply and irrigation in the region. With its strategic location and significant storage capacity, this dam plays a pivotal role in sustaining agricultural activities and water resource management in Bryan County, Oklahoma.

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.
