Summary
Completed in 1950, this structure serves as a crucial water resource for the area, with a storage capacity of 350 acre-feet and a maximum discharge of 400 cubic feet per second. The dam stands at a height of 25 feet and stretches 410 feet in length, providing essential flood control and water management for the region.
Managed by the Oklahoma Water Resources Board, George Nadine is regulated, inspected, and enforced to ensure its safety and functionality. With a low hazard potential and a very high risk assessment rating, this dam is essential for mitigating potential risks and ensuring the safety of downstream communities. The structure features a controlled spillway and a valve outlet gate, highlighting its modern design and operational efficiency.
Despite being classified as not rated in terms of condition assessment, George Nadine remains a vital component of the local water infrastructure. As climate change continues to impact water resources, dams like George Nadine play a crucial role in managing water supply, flood control, and overall climate resilience in the region. With its strategic location on TR-Snake Creek and its capacity to withstand potential risks, George Nadine stands as a testament to effective water resource management in Oklahoma.

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.
