Summary
Completed in 1961, this earth dam stands at a height of 22 feet and has a storage capacity of 130 acre-feet. It serves as a critical structure on Wolf Creek, with a controlled spillway and a valve outlet gate for water management.
The dam is regulated and inspected by the Oklahoma Water Resources Board, ensuring its compliance with state safety standards. While the condition assessment is currently not rated, the dam has undergone regular inspections every five years, with the last inspection conducted in February 2010. Despite its low hazard potential, the high risk assessment highlights the importance of implementing effective risk management measures to mitigate potential threats.
For water resource and climate enthusiasts, Rees presents an intriguing case study of a privately owned dam in Oklahoma. Its location in a high-risk area underscores the importance of proactive monitoring and maintenance to ensure the safety and integrity of the structure. With its unique design and purpose, Rees serves as a valuable asset for water management in the region, showcasing the intersection of infrastructure, regulation, and environmental stewardship in the face of changing climate conditions.

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.
