Summary
With a hydraulic height of 10.8 feet and a structural height of 14.4 feet, the earth dam spans 450 feet in length and has a storage capacity of 69 acre-feet. Despite being classified as low hazard potential and not currently rated for condition assessment, the dam's risk assessment is moderate (3), prompting the need for ongoing monitoring and management.
Operated by a private owner, the Jackson dam is not regulated by the state and does not have associated structures or outlet gates. Its spillway type is uncontrolled, and it has a surface area of 8.6 acres within a drainage area of 0.31 square miles. With a primary purpose not specified, the dam is situated in a picturesque location within Benton County, Tennessee, providing a valuable source of water storage for local agricultural and environmental needs.
While the Jackson dam may not be subject to regular state inspection or permitting, its location within the Nashville District of the US Army Corps of Engineers ensures a level of oversight and adherence to safety standards. With a congressman representing the area, potential future modifications or upgrades to the dam may be guided by federal regulations and funding. As water resource and climate enthusiasts monitor the evolving landscape of water management, the Jackson dam stands as a reminder of the critical role of infrastructure in sustaining communities and ecosystems.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
