Summary
Built in 1960 by the USDA NRCS, this earth dam with a buttress core stands at 12 feet high and has a storage capacity of 96 acre-feet. The dam is regulated by the Mississippi Department of Environmental Quality and is inspected, permitted, and enforced by the state regulatory agency to ensure its safe operation.
Situated on TR-Island Creek, the Grover Brown Lake Dam boasts a low hazard potential and a moderate risk assessment rating. While the dam has not been rated for condition assessment, it is constantly monitored to ensure its structural integrity and functionality. With uncontrolled spillways and outlet gates, the dam provides recreational opportunities for the community while serving as a vital water resource in the area.
The dam's location in Jefferson County, Mississippi, under the jurisdiction of the Vicksburg District, highlights its importance in water resource management. With a focus on recreation and a history dating back to 1960, Grover Brown Lake Dam remains a significant structure that contributes to the local ecosystem and supports the surrounding community's water needs.

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.
