Jackson dam
Jackson
Jackson is a private dam located on Turkey Creek in Decatur, Tennessee, completed in 1958. With a hydraulic height of 11.8 feet and a structural height of 16.2 feet, Jackson serves as a significant water storage facility with a capacity of 145 acre-feet. The dam has a spillway type of "Uncontrolled" and a length of 420 feet, providing essential flood control and water resource management for the area.
Although not state-regulated, Jackson poses a significant hazard potential and has a moderate risk assessment rating. The dam has not been recently assessed for its condition, but it is crucial for stakeholders and climate enthusiasts to monitor and maintain the structure to prevent any potential hazards. Despite its age, Jackson continues to play a vital role in the local water infrastructure, demonstrating the importance of sustainable water resource management in the face of changing climate patterns and environmental challenges.
As part of the Nashville District, Jackson stands as a testament to the engineering feats of its time and the ongoing need for effective dam management practices. With its historical significance and functional importance in water storage and flood control, Jackson serves as a reminder of the critical role that dams play in ensuring water security and resilience in the face of climate variability. As water resource and climate enthusiasts continue to advocate for sustainable practices, understanding and monitoring structures like Jackson are essential for safeguarding communities and ecosystems for generations to come.

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 Jackson
Where does the data for Jackson 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 Significant 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.
