Summary

Built in 1950, this Earth-type dam stands at a height of 35 feet and has a maximum storage capacity of 100 acre-feet. Situated along the TR-Little Walnut Creek, this dam serves as a popular spot for outdoor enthusiasts seeking water-based activities in the area.

Managed by the Oklahoma Water Resources Board, Oknoname 107022 has been designated as a low hazard potential structure with a very high risk assessment rating. Despite its age, the dam has not been rated for its condition and has not undergone recent inspection or evaluation. Equipped with a controlled spillway and a single valve outlet gate, this recreational reservoir covers a surface area of 2 acres and is a prime location for fishing, boating, and other water recreation activities.

While Oknoname 107022 offers a picturesque setting for visitors to enjoy, its lack of recent assessment and maintenance raises concerns about its long-term stability and safety. As water resource and climate enthusiasts, it is important to advocate for the proper monitoring and upkeep of such structures to ensure the protection of both the environment and public safety in the region.

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.
