Nelle Gray Pond Dam dam
Nelle Gray Pond Dam
Nestled in DeSoto County, Mississippi, the Nelle Gray Pond Dam stands as a testament to sustainable water resource management and climate resilience. Built in 1956 by the USDA NRCS, this private-owned earth dam serves a primary purpose of recreation along the TR- Horn Lake Creek -OS. With a height of 14 feet and a storage capacity of 96 acre-feet, the dam boasts a low hazard potential and satisfactory condition assessment, ensuring its structural integrity for the community of JAGO and beyond.
Managed by the Mississippi Department of Environmental Quality, the Nelle Gray Pond Dam is subject to state regulations, inspections, and enforcement measures to uphold safety standards. Despite being uncontrolled, the dam's spillway and outlet gates have been designed to mitigate potential risks and ensure effective water discharge during extreme events. With a moderate risk assessment rating and a history of regular inspections, the dam remains a reliable resource for recreational activities while maintaining a focus on environmental conservation and public safety.
As part of the Vicksburg District, the Nelle Gray Pond Dam exemplifies the collaboration between federal and state agencies in overseeing water infrastructure projects. With a focus on sustainable practices and risk management, the dam serves as a model for other earth dams in the region. By harnessing the expertise of the Natural Resources Conservation Service and implementing effective regulatory measures, the dam continues to play a vital role in supporting the local community and promoting responsible water resource management in Mississippi.

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 Nelle Gray Pond Dam
Where does the data for Nelle Gray Pond 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.
