Summary
is a privately owned dam located in Comanche, Oklahoma, near the city of COXS CORNER. Built in 1955, this Earth dam stands at a height of 20 feet and has a storage capacity of 70 acre-feet. It serves as a critical structure for the TR-NINEMILE BEAVER CR river system in the area, with a controlled spillway and a single valve outlet gate for water management.
Despite its low hazard potential, Mayhugh T.C. is under the regulatory oversight of the Oklahoma Water Resources Board (OWRB), with state permitting, inspection, and enforcement in place to ensure its safety and compliance. The dam has not been recently assessed for its condition, but it is categorized as "Very High (1)" in terms of risk assessment, highlighting the importance of ongoing monitoring and maintenance to prevent any potential issues.
For water resource and climate enthusiasts, the Mayhugh T.C. dam presents an intriguing case study in dam infrastructure management. With a history dating back to the mid-20th century and a unique design featuring Stone core and Soil foundation, this structure plays a crucial role in water storage and management in the region. As efforts continue to assess and address potential risks associated with the dam, it serves as a reminder of the importance of sustainable water resource practices in the face of changing environmental conditions.

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.
