Summary
is a private dam located in Harper County, Oklahoma, specifically in the city of Freedom. This earth dam, completed in 1965, stands at a height of 25 feet and has a length of 420 feet. It serves as a vital structure along the TR-Cimarron River, with a storage capacity of 150 acre-feet and a maximum discharge of 360 cubic feet per second.
Managed by the Oklahoma Water Resources Board, Carmichael Betty Jo T. is regulated, permitted, inspected, and enforced by the state agency. Despite being rated as having low hazard potential, the dam is classified as having a very high risk due to its condition assessment being labeled as 'Not Rated'. With a controlled spillway and one valve outlet gate, the dam's emergency action plan and risk management measures are currently not up to date.
For water resource and climate enthusiasts, Carmichael Betty Jo T. presents an interesting case study in dam infrastructure and risk assessment. The dam's location along the TR-Cimarron River, its design as an earth dam with stone core and soil foundation, and its history of completion in the mid-20th century all contribute to its importance in the local water management system. As discussions and actions continue regarding its risk management and emergency preparedness, Carmichael Betty Jo T. serves as a focal point for ongoing efforts to ensure the safety and sustainability of water resources in the region.

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.
