Summary
Built in 1956, this dam stands at a structural height of 17 feet and has a hydraulic height of 11.7 feet. With a storage capacity of 142 acre-feet and a normal storage of 65 acre-feet, Grand Valley #2 covers a surface area of 13.8 acres and serves the purpose of flood control and water storage.
Managed by the Tennessee Safe Dams Program, Grand Valley #2 is regulated, permitted, inspected, and enforced by the state agency to ensure its structural integrity and safety. The dam has a significant hazard potential and is classified as having a moderate risk level. Despite this, its condition assessment in 2020 was deemed satisfactory, indicating that necessary maintenance and repairs have been conducted to uphold its functionality.
With a history of regular inspections and a satisfactory condition assessment, Grand Valley #2 showcases Tennessee's commitment to ensuring the safety and reliability of its water infrastructure. As water resource and climate enthusiasts, it is important to monitor and support the maintenance of dams like Grand Valley #2 to mitigate potential risks and safeguard our communities against flooding and water shortages.

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.
