Summary
This dam on TR-Horse Creek serves multiple purposes, with a primary purpose listed as "Other." It has a height of 30 feet and a length of 350 feet, providing a storage capacity of 60 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular state inspection, enforcement, and permitting.
Despite being rated as having a low hazard potential, Cornell George has a very high risk assessment, indicating a need for careful risk management measures. The dam features a controlled spillway and one valve for outlet gates. Its last inspection was conducted in July 2011, with a recommended inspection frequency of every 5 years. The dam's condition is currently listed as "Not Rated," and no emergency action plan or inundation maps have been prepared.
Overall, Cornell George presents an intriguing case study for water resource and climate enthusiasts, showcasing the complexities involved in managing and assessing the risk of dams. With its unique design and purpose, this privately owned dam serves as a vital water management structure in Custer, Oklahoma, highlighting the importance of regular inspection and maintenance to ensure public safety and environmental protection.

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.
