Summary
With a primary purpose of flood risk reduction, this earth dam stands at a height of 24 feet and has a length of 335 feet, providing a maximum storage capacity of 64 acre-feet and a normal storage of 22 acre-feet. The dam is classified as high hazard potential and has an unsatisfactory condition assessment as of the last inspection in June 2015.
Managed by the USDA NRCS, the Abiaca Watershed Structure Y-34-29 Dam is regulated by the Mississippi Department of Environmental Quality, with state permitting, inspection, and enforcement in place. The dam's spillway type is uncontrolled, and it features uncontrolled outlet gates. Although the risk assessment is moderate, with a risk level of 3, there are currently no designated emergency action plans or inundation maps prepared for the dam, highlighting the importance of ongoing risk management measures and updates to ensure the safety of surrounding communities in case of emergencies.

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.
