Summary

This dam is regulated by the Oklahoma Water Resources Board and is designed by USDA NRCS. It stands at a height of 14.5 feet with a storage capacity of 204.53 acre-feet.

The primary purpose of Oknoname 30214 is categorized as 'Other', and it has a controlled spillway with a width of 1 foot. The dam has a low hazard potential and is currently assessed as 'Not Rated'. Although it has a very high risk assessment score of 1, the inspection frequency is set at 5 years. The dam has not been modified in recent years, and there is no emergency action plan in place.

Overall, Oknoname 30214 serves as an essential water resource structure in the region, contributing to the management of water flow in the unnamed tributary of Uncle John Creek/Cimarron. Its presence underscores the importance of proper regulatory oversight and maintenance to ensure the safety and effectiveness of such critical infrastructure in the face of climate change and water scarcity challenges.

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.
