Summary
Built in 1965 by the USDA NRCS, this earth dam stands at a height of 39 feet and has a storage capacity of 2686.73 acre-feet, serving the primary purpose of flood risk reduction along the TR-Abiaca Creek. The dam is owned by the local government and regulated by the Mississippi Department of Environmental Quality, ensuring its safe operation and maintenance.
Despite its importance in mitigating flood risks, the Abiaca Watershed Structure Y-34-09 Dam has been assessed as having a high hazard potential and an unsatisfactory condition as of August 2018. Regular inspections are conducted every 5 years to monitor its structural integrity and functionality. The dam's spillway is uncontrolled, and it poses a moderate risk (level 3) according to the risk assessment. With its location in a high-risk area, emergency preparedness measures are crucial for ensuring the safety of surrounding communities in case of a dam failure.
The Abiaca Watershed Structure Y-34-09 Dam plays a vital role in protecting the local area from flooding events and is a key component of the water resource management infrastructure in Mississippi. As climate change continues to impact weather patterns and increase the frequency of extreme weather events, the maintenance and proper functioning of this dam are essential for safeguarding the community and surrounding environment from potential disasters.

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.
