Summary
Managed by the Tennessee Safe Dams Program, this dam stands at a height of 18.9 feet with a hydraulic height of 15.1 feet, serving a primary purpose not specified in the data. The dam has a significant hazard potential and was last inspected in August 2019, with a satisfactory condition assessment reported.
With a storage capacity of 348 acre-feet, Rebecca Lake covers a surface area of 32 acres and drains an area of 2.51 square miles. The dam features an uncontrolled spillway and no outlet gates, with a moderate risk assessment rating of 3. Despite its moderate risk level, the dam's condition is deemed satisfactory, indicating that it is adequately maintained and poses no immediate danger to downstream areas.
Rebecca Lake's presence on the Washburn Branch contributes to the water resource management in the region, highlighting the importance of proper dam maintenance and regulatory oversight. With its history dating back to 1950, this earth dam serves as a vital piece of infrastructure in the area, showcasing the intersection of water resource management, climate resilience, and dam safety.

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.
