Summary

The dam stands at a height of 25 feet and has a length of 280 feet, with a maximum storage capacity of 120 acre-feet. Despite being categorized as low hazard potential, the dam is under the regulatory oversight of the Oklahoma Water Resources Board and is subject to regular inspections, with the last one conducted in December 2010.

The dam features a controlled spillway and a single valve outlet gate, with a surface area of 4 acres and a normal storage capacity of 90 acre-feet. While the condition of the dam is currently not rated, the risk assessment indicates a very high risk level (1). The dam is situated in Tulsa County, Oklahoma, within the jurisdiction of the Tulsa District of the US Army Corps of Engineers. Although no modifications have been recorded in recent years, the dam remains an essential structure for recreational activities in the area.

Water resource and climate enthusiasts will find Oknoname 143014 to be an intriguing case study of a privately owned dam with a unique design and operational characteristics. The dam's location on the TR-ARKANSAS RIVER offers opportunities for recreation and leisure, while also highlighting the importance of proper maintenance and inspection to ensure public safety and environmental protection. With its historical significance and regulatory oversight by the Oklahoma Water Resources Board, Oknoname 143014 serves as a valuable asset in the management of water resources in Tulsa County, Oklahoma.

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.
