Summary
Managed by the TENNESSEE SAFE DAMS PROGRAM, this earth dam stands at 21 feet tall with a hydraulic height of 15.2 feet and a length of 370 feet. Completed in 1954, it provides a storage capacity of 138 acre-feet and covers a surface area of 12.1 acres, serving as a crucial water resource for the region.
With a low hazard potential and a satisfactory condition assessment as of April 2020, Dalton poses a moderate risk level. Despite its uncontrolled spillway type, the dam meets regulatory standards with state-permitted inspections, enforcement, and maintenance in place. The overall risk management measures and emergency preparedness status are yet to be fully detailed, but the dam's structure and operational integrity reflect a commitment to water resource safety and climate resilience in the area.
Dalton's presence in the Nashville District underscores its significance in the local water infrastructure network. As water resource and climate enthusiasts continue to monitor and advocate for sustainable practices, Dalton's role in maintaining water security and mitigating risks highlights the interconnectedness of dams to environmental stewardship and community well-being in Tennessee.

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.
