Summary
This earth dam, with a height of 34.9 feet and a storage capacity of 1121 acre-feet, serves the primary purpose of flood risk reduction along Curtis Branch. The dam is regulated by the Mississippi Department of Environmental Quality and is designated as having a high hazard potential with a fair condition assessment as of February 2020.
The Sowashee Creek WS Str No 2 Dam features an uncontrolled spillway with a maximum discharge capacity of 1766 cubic feet per second and a drainage area of 2.56 square miles. The dam's normal storage capacity is 123 acre-feet, covering a surface area of 35 acres. Despite its moderate risk assessment rating, the dam has not undergone any significant modifications since its completion and is inspected every five years to ensure its structural integrity and continued flood protection capabilities. For water resource and climate enthusiasts, the Sowashee 2 Dam presents an intriguing case study in flood risk management and dam safety in the state of Mississippi.

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.
