Summary
Completed in 1940, this dam serves multiple purposes and has a storage capacity of 110 acre-feet, with a normal storage level of 50 acre-feet. The dam is situated on Gilbert Creek, within the Tulsa District of Oklahoma, and is regulated by the OWRB, ensuring proper inspection, enforcement, and permitting.
Despite being classified as having a low hazard potential, Oknoname 059054 is deemed to have a very high risk level, indicating the importance of effective risk management measures. The dam features a controlled spillway, one valve outlet gate, and a stone core foundation. It has not been rated for its condition assessment, with the last inspection taking place in August 2011. While the dam has not been modified over the years, it remains a crucial structure for water resource management in the region, serving as a testament to the collaboration between private owners and federal agencies in safeguarding water sources in Oklahoma.
Overall, Oknoname 059054 stands as a vital component of water infrastructure in Oklahoma, contributing to flood control, irrigation, and water supply management in the region. With its historical significance, structural design, and regulatory oversight, this dam exemplifies the importance of maintaining and monitoring water resources to ensure their sustainability and safety for future generations. As water resource and climate enthusiasts, understanding the intricacies of structures like Oknoname 059054 sheds light on the critical role they play in mitigating risks and enhancing water security in the face of changing environmental conditions.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
