Summary
Built in 1960, this earth dam stands at a height of 15 feet and has a storage capacity of 67 acre-feet. Its primary purpose is listed as "Other," with a low hazard potential and a high risk assessment rating of 1. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular state inspection, permitting, and enforcement.
Despite its low hazard potential, Flint Ja has a very high risk assessment due to its critical location and the potential impact it could have on the surrounding area in the event of a failure. The dam has a controlled spillway with a width of 1 foot and an outlet gate consisting of a single valve. The last inspection of the dam was conducted in August 2011, with a scheduled inspection frequency of every 5 years. While the condition of the dam is currently rated as "Not Rated," it is essential that ongoing risk management measures are in place to ensure the safety and stability of the structure.
Given the high risk assessment associated with Flint Ja, it is crucial that emergency action plans (EAPs) are prepared and regularly updated to meet guidelines and ensure the safety of nearby residents in the event of a dam failure. With a very high risk classification and a low hazard potential, the dam presents a significant challenge for risk management and mitigation efforts. Close monitoring and proactive measures are essential to address any potential threats and protect the surrounding community from the consequences of a dam failure.

Dam Data Reference
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.
