Summary
is a state-owned dam located in Harper County, Oklahoma, specifically in the city of Freedom. Built in 1960, this earth dam stands at a height of 24 feet and has a length of 370 feet, providing a storage capacity of 320 acre-feet. Situated on the TR-Cimarron River, Carmichael Betty Jo T. serves multiple purposes with a primary purpose designated as "Other".
Although the dam is classified as having a low hazard potential, it is rated as being in very high risk due to its condition assessment being marked as "Not Rated". The dam is regulated, permitted, inspected, and enforced by the Oklahoma Water Resources Board (OWRB), ensuring that it meets state standards for safety and operation. With a controlled spillway and a single valve outlet gate, Carmichael Betty Jo T. remains an essential structure in managing water resources and mitigating flood risks in the area.
For water resource and climate enthusiasts, Carmichael Betty Jo T. offers an intriguing case study of dam infrastructure management. Its location on the TR-Cimarron River, the oversight by OWRB, and the considerations of hazard potential and risk assessment all contribute to a comprehensive understanding of how dams play a crucial role in water management and climate resilience. As efforts continue to ensure the safety and functionality of Carmichael Betty Jo T., it serves as a reminder of the ongoing importance of monitoring and maintaining critical water infrastructure 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.
