Summary
Built in 1977 by the USDA NRCS, this dam stands at 25 feet tall with a hydraulic height of 20 feet and a length of 759 feet. Its primary purpose is flood risk reduction, providing a storage capacity of 150 acre-feet and a maximum discharge of 1000 cubic feet per second.
Managed by the Oklahoma Water Resources Board, Smith George has a low hazard potential and has not been rated for condition assessment. Despite its age, the dam has undergone regular inspections with the last one conducted in August 2011. With a very high risk assessment rating of 1, the dam is equipped with a controlled spillway and a valve outlet gate to manage water levels in case of emergencies. Its location in Hughes County highlights the importance of maintaining and monitoring this critical infrastructure for water resource and climate enthusiasts.
Overall, Smith George serves as a vital flood risk reduction structure in Oklahoma, contributing to the state's water resource management efforts. Despite its age, the dam remains a key asset in mitigating flood risks along the TR-Wewoka Creek. With ongoing inspections and regulatory oversight by the OWRB, this earth dam continues to play a crucial role in protecting communities and infrastructure in the region. For those passionate about water resources and climate resilience, Smith George represents a noteworthy example of infrastructure designed to withstand the challenges of a changing climate.

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.
