Summary

Built in 1955, this Earth type dam stands at 16 feet high with a hydraulic height of 13 feet and a length of 444 feet. The dam serves the primary purpose of "Other" and has a storage capacity of 53 acre-feet, with a normal storage level of 43 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and is inspected, permitted, and enforced by the state regulatory agency.

Despite being classified as having a low hazard potential, the risk assessment for Oknoname 033004 indicates a very high risk level. The dam features a controlled spillway with a width of 1 foot and an outlet gate consisting of a single valve. The inspection frequency for this dam is every 5 years, with the last inspection conducted in September 2010. The dam is situated on TR WEST CACHE CREEK and falls under the jurisdiction of the Fort Worth District of the US Army Corps of Engineers.

With its unique design and critical importance in managing water resources in the area, Oknoname 033004 stands as a testament to the complex interplay between human infrastructure and natural systems. As climate change impacts continue to influence water availability and usage patterns, understanding and maintaining structures like Oknoname 033004 will be crucial in ensuring sustainable water management practices for future generations.

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.
