Summary

Designed by USDA NRCS and completed in 2000, this stone dam stands at a height of 17.2 feet with a hydraulic height of 11.4 feet. With a storage capacity of 84.17 acre-feet and a surface area of 4.48 acres, it serves a variety of purposes including flood control and irrigation.

Although the dam has a low hazard potential, it is classified as having a very high risk due to its structural condition not being rated. Despite this, it is regularly inspected and maintained by the OWRB to ensure its safety and functionality. With a controlled spillway and a maximum discharge of 109.2 cubic feet per second, Oknoname 30162 plays a crucial role in managing water resources and mitigating potential risks in the region.

Overall, Oknoname 30162 is a vital infrastructure that contributes to water resource management in Oklahoma. Its strategic location and efficient design make it a key player in regulating the flow of the CIMARRON river and protecting the surrounding communities from potential flooding events. With ongoing inspections and maintenance, this dam continues to serve its purpose effectively while ensuring the safety and well-being of the residents in the area.

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.
