Summary
The dam, with a height of 20 feet and a storage capacity of 162 acre-feet, is classified as an earth dam with a buttress core and soil foundation. It is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections to ensure its safe operation.
The dam's spillway is uncontrolled, and it has a low hazard potential with a moderate risk assessment rating. While its condition is currently not rated, Carson Lake Dam is maintained by the Natural Resources Conservation Service. The dam is situated on TR- Grogg Creek in Benton County and is under the jurisdiction of the state of Mississippi. With its picturesque location and importance for water resource management in the area, Carson Lake Dam serves as a key infrastructure for both recreational and environmental purposes.
Despite being privately owned, Carson Lake Dam plays a crucial role in water management and conservation efforts in the region. With a focus on recreation, the dam provides opportunities for outdoor activities while also contributing to the overall ecological balance of the area. As a part of the larger water infrastructure in Mississippi, Carson Lake Dam showcases the importance of responsible dam management and the integration of recreational needs with environmental stewardship.

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.
