Summary
Completed in 1960, this dam stands at a height of 35 feet and has a storage capacity of 90 acre-feet. With a spillway type of Controlled, the dam has a low hazard potential and is not currently rated for its condition assessment. Despite its age, Oknoname 037005 has undergone regular state inspections, with the last inspection conducted in August 2011.
Managed by the Oklahoma Water Resources Board (OWRB), this dam serves a primary purpose that is classified as "Other." It is designed with a stone core and a soil foundation, with a hydraulic height matching its structural height of 35 feet. The dam boasts a maximum discharge capacity of 4900 cubic feet per second and is equipped with a single valve outlet gate. While the risk assessment for Oknoname 037005 is categorized as "Very High (1)," it is important to note that the dam has not had any major modifications over the years and is considered to have a low hazard potential.
As a part of the Tulsa District, this dam is located in Creek County, Oklahoma, and is under state jurisdiction and regulation. While the dam has not been rated for its condition assessment, it is crucial for water resource and climate enthusiasts to monitor the maintenance and risk management measures of Oknoname 037005 to ensure the safety and sustainability of the surrounding area and water resources.

Dam Data Reference
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.
