Summary
This earth dam was completed in 1985 and has a hydraulic height of 10 feet and a structural height of 19 feet. The dam has a storage capacity of 550 acre-feet, with a normal storage level of 205 acre-feet and a surface area of 43 acres.
Managed by the Tennessee Safe Dams Program, Sheffield Branch serves as a vital structure for water resource management in the region. With a drainage area of 0.93 square miles, the dam plays a crucial role in flood control and water supply. Despite its moderate risk assessment level, the dam has undergone regular inspections, with the last one conducted in March 2019, to ensure its safety and functionality for the surrounding community.
The dam features an uncontrolled spillway and has no outlet gates or associated structures. While the risk potential is deemed moderate, the dam's condition remains satisfactory, reflecting ongoing efforts to maintain its integrity and mitigate potential hazards. As an essential component of the water infrastructure in the area, Sheffield Branch underscores the importance of proactive dam management and monitoring in safeguarding water resources and addressing climate-related challenges.

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.
