Summary

Built in 1964, this earth dam stands at 32 feet high and has a storage capacity of 240 acre-feet. While its primary purpose is listed as "Other," the dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last one conducted in October 2009. Despite its low hazard potential, the risk assessment for Oknoname 151001 is rated as "Very High (1)."

Managed by private owners, Oknoname 151001 is equipped with a controlled spillway and a single valve outlet gate. The dam spans 420 feet in length and covers a surface area of 1 acre. Although its condition assessment is currently "Not Rated," the dam is considered to have a very high risk level, emphasizing the importance of proper risk management measures. With its location in the Tulsa District of Oklahoma, Oknoname 151001 is a crucial structure for water resource and climate enthusiasts to monitor and assess for potential environmental impacts and safety concerns.

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.
