Summary
Constructed in 2007, this Earth-type dam stands at a height of 35.2 feet and has a maximum storage capacity of 37 acre-feet. The dam, designed by John S Wilson, P.E., overlooks the UNT of Grays Creek and is regulated by the Mississippi Department of Environmental Quality.
Despite its low hazard potential, Grays Creek North Lake Dam is classified as having a moderate risk level (3). The dam features an uncontrolled spillway type, with a maximum discharge capacity of 134 cubic feet per second. With a surface area of 2 acres and a drainage area of 0.03 square miles, the dam contributes to the local ecosystem and provides opportunities for outdoor activities. Although its condition assessment is currently listed as "Not Rated," the dam undergoes regular state inspection, permitting, and enforcement to ensure its safety and functionality for both visitors and the environment.
Grays Creek North Lake Dam offers a picturesque backdrop for water resource and climate enthusiasts to appreciate the intersection of human engineering with natural landscapes. Its strategic location in Hernando, Mississippi, makes it a focal point for recreation and serves as a testament to effective dam management and regulation by state authorities. As a vital component of the local water infrastructure, this dam presents a unique opportunity to explore the delicate balance between conservation and human recreation in the context of climate change and water resource management.

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.
