Summary
The dam has a height of 15 feet and a hydraulic height of 7 feet, with a maximum storage capacity of 50 acre-feet. It serves a primary purpose other than flood control or water supply, with a low hazard potential and a very high risk assessment rating. Despite being a non-federally owned structure, the dam is regulated by the Oklahoma Water Resources Board and undergoes regular state inspections and enforcement to ensure its safety and integrity.
The dam features a controlled spillway with a width of 1 foot and an outlet gate consisting of a single valve. With a surface area of 5 acres and a normal storage capacity of 25 acre-feet, the dam plays a crucial role in water resource management in the region. While it has not been rated for its current condition, the dam is subject to a regular inspection frequency of 5 years to assess its overall safety and maintenance needs. The surrounding area, including the city of TAFT, relies on the dam for flood protection and water storage, highlighting its importance in the local ecosystem.
Despite its private ownership, Oknoname 145004 stands as a vital infrastructure element in the Tulsa District's water management system. With its earth dam structure and stone core, the dam has been serving its intended purpose effectively for over six decades. Its strategic location on the TR-ARKANSAS RIVER and its relatively low hazard potential make it a key asset in mitigating flood risks and ensuring water availability for the surrounding communities. Ongoing state regulation and inspection efforts further underscore the commitment to maintaining the dam's safety and functionality for the benefit of all stakeholders involved in water resource management and climate resilience in the region.

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.
