Summary
Built in 1958 by the USDA NRCS, this earth-type dam serves primarily for flood risk reduction along the TR-Okonatie Creek. Standing at a height of 26 feet and a length of 590 feet, the dam has a storage capacity of 220 acre-feet and covers a surface area of 10 acres.
Managed by the Mississippi Department of Environmental Quality, this dam is state-regulated, with inspection, permitting, and enforcement procedures in place to ensure its safety and functionality. The dam's hazard potential is rated as low, with a moderate risk assessment score of 3. Although the condition assessment is currently not rated, the dam has not undergone any recent modifications and is equipped with uncontrolled spillways and outlet gates.
For water resource and climate enthusiasts, the Okonatie WS Str Ut 25 2 Dam presents an interesting case study in local government ownership and flood risk management. With a focus on reducing the impact of flooding in the area, this dam plays a crucial role in protecting the surrounding community and the environment. As part of ongoing risk management measures, it is essential to continue monitoring and maintaining the dam to ensure its long-term sustainability and effectiveness in mitigating flood risks.

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.
