Summary
Perry Dam, is a vital flood risk reduction infrastructure located in Carroll, Mississippi. Built in 1968 by the USDA NRCS, this earth-core dam stands at a height of 41 feet and has a storage capacity of 1351 acre-feet. The dam serves the primary purpose of flood risk reduction along the TR- Coila Creek, with a hazard potential rated as high and a fair condition assessment.
The dam is regulated by the Mississippi Department of Environmental Quality, with state jurisdiction, permitting, inspection, and enforcement in place. The structure is associated with the Vicksburg District of the USACE and is located in close proximity to the city of Sidon. With a drainage area of 3.65 square miles and a surface area of 22.3 acres, the dam plays a crucial role in managing water resources and protecting the surrounding communities from potential flooding events.
Despite its high hazard potential, the Abiaca Watershed Structure Y-34-04 Dam is considered to have a moderate risk level (3) with risk management measures in place. Regular inspections and a designated emergency action plan contribute to the structure's overall safety and effectiveness in flood risk reduction. For water resource and climate enthusiasts, this dam serves as a significant example of infrastructure designed to safeguard communities against natural disasters like flooding while also highlighting the importance of effective water resource management practices.

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.
