Jones dam
Jones
Jones, a privately owned dam located in Gibson County, Tennessee, serves multiple purposes including fire protection, stock maintenance, and small fish pond management. Completed in 1996, this Earth-type dam on the TRIBNO. FORK FORKED DEER river boasts a hydraulic height of 16.2 feet and a structural height of 20.7 feet, with a total length of 600 feet and a storage capacity of 86 acre-feet. Despite its low hazard potential and moderate risk assessment rating, Jones has not been rated for its overall condition and lacks an Emergency Action Plan (EAP) as of the last inspection in 2017.
Managed by the Memphis District of the U.S. Army Corps of Engineers, Jones has not undergone any modifications or received federal funding or oversight. With a surface area of 6.7 acres and a drainage area of 0.12 square miles, the dam is equipped with an uncontrolled spillway and has no outlet gates or associated structures. While it does not fall under state regulation or permitting, Jones poses a moderate risk due to its location and lack of current risk management measures or emergency preparedness guidelines.
For water resource and climate enthusiasts, Jones presents an intriguing case study of a privately owned dam in rural Tennessee with multiple functional purposes and a moderate risk assessment. With its unique design features and lack of federal or state regulatory oversight, Jones offers insights into the challenges and considerations involved in managing small-scale dams for community needs such as fire protection and stock maintenance. Further investigation into its condition assessment, risk management measures, and emergency preparedness could provide valuable lessons for similar structures 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 Jones
Where does the data for Jones 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.
