Summary
Gilead, located in Henderson, Tennessee, is a state-regulated dam that stands as a critical water resource structure in the region. Completed in 1981, this earth dam on the Middle Fork Forked Deer River boasts a hydraulic height of 13.2 feet and a structural height of 21.5 feet, with a total length of 450 feet. With a normal storage capacity of 72 acre-feet and a maximum storage of 160 acre-feet, Mt. Gilead serves as a key component in managing water resources and protecting against potential flooding in the area.
Managed by the Tennessee Safe Dams Program, Mt. Gilead is subject to regular inspections, with its last assessment conducted in July 2020 resulting in a satisfactory condition assessment. The dam's hazard potential is classified as low, with a moderate risk level of 3, indicating the need for ongoing risk management measures. Despite its relatively low risk profile, Mt. Gilead plays a crucial role in supporting water supply and climate resilience efforts in the region, highlighting the importance of maintaining and monitoring this essential infrastructure for the community.
As part of the Nashville District, Mt. Gilead is a testament to the collaborative efforts between state and federal agencies in ensuring the safety and functionality of water resource structures. With its uncontrolled spillway type and moderate risk assessment, Mt. Gilead stands as a reliable asset for water management in Henderson, Tennessee, embodying the intersection of environmental stewardship, infrastructure resilience, and climate adaptation in the region.

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.
