Summary

The dam, designed by USDA NRCS, stands at a height of 19.3 feet and has a hydraulic height of 20.3 feet. It has a storage capacity of 169.72 acre-feet and a normal storage level of 95.47 acre-feet, serving as a vital water resource in the area.

The dam's low hazard potential is complemented by its controlled spillway type and the presence of a single valve outlet gate. Despite being in a very high-risk area, the dam's condition has not been rated, and its last inspection dates back to 2009. With state regulation and enforcement in place, as well as regular inspections, Oknoname 30238 is a crucial piece of infrastructure that contributes to water management and climate resilience efforts in the region.

Located on a tributary to Kiamichi River, Oknoname 30238 plays a crucial role in managing water resources in the area. With its strategic design and state-regulated operations, the dam serves as a key asset in mitigating risks and ensuring water security for the surrounding communities. As a focal point for water resource and climate enthusiasts, this dam represents a vital component of the region's environmental infrastructure.

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.
