Summary

Built in 1974, this earth dam stands at a height of 45 feet and has a storage capacity of 2160 acre-feet. Despite its low hazard potential, it is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last inspection dating back to August 2006.

The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 26,752 cubic feet per second. Its primary purpose is listed as "Other" and it serves various purposes related to water resource management. The risk assessment for Oknoname 113025 classifies it as having a very high risk factor, with a risk level of 1, indicating the need for careful monitoring and management measures to ensure safety and functionality.

Although the dam's condition has not been rated, it is crucial to have emergency action plans in place in case of any unforeseen events. With its strategic location in Osage County, Oklahoma, and its importance for water resource management in the region, Oknoname 113025 serves as a vital infrastructure that requires ongoing attention and maintenance to safeguard against potential risks and ensure its continued operation for the community.

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.
