Summary
Built in 1961 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the TR- Grays Creek. With a height of 31 feet and a storage capacity of 482 acre-feet, this structure plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the local government and regulated by the Mississippi Department of Environmental Quality, the Grays Creek Watershed Dam is classified as having a low hazard potential with a moderate risk assessment. While not currently rated for its condition, this dam is inspected, permitted, and monitored by state agencies to ensure its safety and effectiveness in flood risk management. Its uncontrolled spillway and outlet gates contribute to its design as a buttress-type earth dam, tailored to handle the drainage needs of the 1.14 square-mile watershed it serves.
For water resource and climate enthusiasts, the Grays Creek Watershed Structure G-6-04 Dam represents a vital piece of infrastructure in Mississippi's flood risk reduction efforts. With its strategic location in the Memphis District and its association with the Natural Resources Conservation Service, this dam stands as a testament to the collaborative efforts of government agencies in safeguarding communities from the impacts of extreme weather events. As climate change continues to pose challenges to water management, structures like the G-6 Dam 4 play a crucial role in enhancing resilience and adaptation 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.
