Summary
Constructed in 1965 by the USDA NRCS, this earth dam with a height of 35 feet serves the primary purpose of mitigating the risk of flooding along the TR- ABOTLAPUTA CREEK. Managed by the local government, this dam is regulated by the Mississippi Department of Environmental Quality to ensure its safety and effectiveness.
With a storage capacity of 674 acre-feet, the Abiaca Watershed Structure Y-34-12 Dam plays a crucial role in protecting the surrounding area from potential flood events. Despite its low hazard potential, the dam's condition was assessed as unsatisfactory during the last inspection in 2016. The risk assessment categorizes the dam as having a moderate risk level, indicating the need for ongoing monitoring and maintenance to ensure its continued reliability in safeguarding the community from flooding.
While the dam currently operates with uncontrolled spillways and outlet gates, efforts are being made to address its condition and reduce the risk associated with its operation. As water resource and climate enthusiasts, it is essential to recognize the significance of structures like the Abiaca Watershed Structure Y-34-12 Dam in managing water flow and protecting communities from the impacts of extreme weather events. By staying informed and supporting initiatives to improve dam safety and resilience, we can contribute to the sustainable management of our water resources and enhance the overall resilience of our communities in the face of a changing climate.

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.
