Summary

Completed in 1979, this earth dam stands at a height of 30 feet and has a storage capacity of 69 acre-feet. The dam serves the primary purpose of irrigation, with a normal storage capacity of 35 acre-feet and a surface area of 12 acres. Despite its low hazard potential, it is state regulated by the Oklahoma Water Resources Board and undergoes regular inspections and enforcement to ensure its safety and functionality.

Situated on SAND CR, Stubbs George falls under the jurisdiction of the Fort Worth District of the U.S. Army Corps of Engineers and is overseen by the Oklahoma state regulatory agency. The dam's spillway is controlled with a width of 1 foot, and it has a single valve outlet gate for water release. With a very high risk assessment rating of 1, the dam's condition is currently not rated, indicating a need for further assessment and potentially an emergency action plan in the future. While the dam remains in operation, its risk management measures and emergency preparedness are areas that may need improvement to ensure the safety of the surrounding area and water resources.

Overall, Stubbs George is a vital structure for irrigation in the region, providing water storage and management for agricultural purposes. As a privately owned dam with state regulation and oversight, its risk management and emergency preparedness are crucial aspects to consider for the safety and sustainability of the surrounding community and environment. Water resource and climate enthusiasts will find interest in the technical details and operational considerations of this important irrigation infrastructure in Bryan 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.
