Summary
Managed by the Oklahoma Water Resources Board, this earth dam structure stands at a height of 28 feet and has a storage capacity of 500 acre-feet. Completed in 1950, Wentz serves primarily for purposes other than flood control or water supply, with a spillway width of 2 feet.
With a low hazard potential and a very high risk assessment rating, Wentz is inspected every 5 years to ensure its structural integrity. Despite being classified as "Not Rated" in terms of condition assessment, the reservoir is equipped with a valve outlet gate and has a controlled spillway type. The surrounding area covers 17 acres and the dam is designed to withstand a maximum discharge rate of 1860 cubic feet per second.
For water resource and climate enthusiasts, Wentz presents an intriguing case study in dam safety and risk management. Its location on TR Duck Creek, within the Tulsa District of Oklahoma, highlights the critical role of private owners and state regulatory agencies in maintaining the integrity of water infrastructure. As climate change continues to impact water resources, the monitoring and maintenance of structures like Wentz will be crucial in ensuring the safety and sustainability of our water supply systems.

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.
