Big Sand Watershed Structure Y-32-27 Dam Reservoir Report
Last Updated: April 1, 2026
The Big Sand Watershed Structure Y-32-27 Dam, also known as Jackson Dam, is a vital infrastructure owned by the local government in Carroll, Mississippi.
Summary
Built in 1971 by the USDA NRCS, this Earth type dam serves the primary purpose of flood risk reduction along the Wagoner Branch river. With a height of 25 feet and a storage capacity of 77 acre-feet, it plays a crucial role in managing water resources in the region.
Managed by the Mississippi Department of Environmental Quality, this dam is regulated, inspected, and enforced by state agencies to ensure its safety and functionality. Despite being categorized as having a low hazard potential, it has a moderate risk assessment score of 3 due to its condition being not rated. Although there are no associated structures or locks, the uncontrolled spillway and outlet gates serve their purpose in managing water flow during times of high discharge, making it a key component in the water resource infrastructure of the area.
Overall, the Big Sand Watershed Structure Y-32-27 Dam stands as a testament to effective flood risk reduction efforts in Mississippi. With its strategic location and design, it continues to play a vital role in protecting the community of TEOC and beyond from potential water-related disasters. As climate change continues to impact water resources, this dam serves as a critical asset in managing and safeguarding the region's hydrological systems.

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.
