Grays Creek North Lake Dam dam
Grays Creek North Lake Dam
Grays Creek North Lake Dam is a private-owned structure located in DeSoto, Mississippi, that serves primarily for recreational purposes. 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
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Grays Creek North Lake Dam
Where does the data for Grays Creek North Lake Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
