Summary
Completed in 1955, this earth dam stands at a height of 21 feet and spans a length of 550 feet along the TR-OWL CREEK. With a storage capacity of 110 acre-feet and a normal storage level of 60 acre-feet, this dam plays a crucial role in managing water resources in the region.
Despite its low hazard potential, Oknoname 087046 is closely regulated by the Oklahoma Water Resources Board (OWRB), with regular inspections and enforcement measures in place. The dam features a controlled spillway and a single valve for outlet gates, ensuring proper water release and management during periods of high discharge. Additionally, the dam's risk assessment indicates a very high risk level, prompting the need for careful monitoring and risk management measures.
Its strategic location in Paoli, within the Tulsa District, further underscores the importance of Oknoname 087046 in the local water infrastructure system. As climate change continues to impact water resources, this dam stands as a vital piece of infrastructure for mitigating flood risks and ensuring sustainable water management practices in the region. With its rich history and ongoing regulatory oversight, Oknoname 087046 remains a key focal point for water resource and climate enthusiasts alike.

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.
