Summary

This earth dam, constructed in 1965, stands at 24 feet high and spans 350 feet in length, providing a storage capacity of 55 acre-feet. Its primary purpose is labeled as "Other", with a design consisting of stone core types and a soil foundation.

Managed by the Oklahoma Water Resources Board, Oknoname 137034 is regulated, permitted, inspected, and enforced by the state agency. The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge of 1,276 cubic feet per second. Despite its condition assessment being marked as "Not Rated", the dam has a regular inspection frequency of 5 years, with the last inspection conducted in September 2011.

For water resource and climate enthusiasts, Oknoname 137034 serves as a significant structure within the Tulsa District, offering valuable insights into the management and maintenance of dams in Oklahoma. With its detailed data on dimensions, storage capacity, and risk assessment, this dam highlights the importance of regulatory oversight and emergency preparedness in safeguarding water resources and communities from potential hazards.

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.
