George Harrell Lake Dam dam
George Harrell Lake Dam
George Harrell Lake Dam, located in Natchez, Mississippi, was completed in 1955 and is primarily used for recreation purposes. This earth dam, with a height of 12 feet, was designed by the USDA NRCS and is regulated by the Mississippi Department of Environmental Quality. The dam has a low hazard potential and is currently rated as not assessed for its condition.
The dam's reservoir has a storage capacity of 90 acre-feet and is situated on the TR- Coles Creek North Fork river or stream. It features an uncontrolled spillway and outlet gates, with no associated locks. The risk assessment for the dam is moderate, and it is not under the jurisdiction of the US Army Corps of Engineers. Despite its age, the dam continues to provide recreational opportunities for the local community and visitors alike.
Overall, George Harrell Lake Dam serves as a vital water resource for the area, offering a tranquil setting for outdoor activities while maintaining a moderate level of risk management. With its historical significance and ongoing recreational value, the dam remains an essential part of the water infrastructure in Jefferson, Mississippi. Its design and construction by the USDA NRCS showcase a commitment to sustainable water management practices in the region.

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 George Harrell Lake Dam
Where does the data for George Harrell 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.
