Summary
5, located in Gibson, Tennessee, was completed in 1986 by the USDA NRCS for flood risk reduction purposes. This Earth-type dam stands at a height of 22 feet with a hydraulic height of 22 feet and a structural height of 25 feet. It spans 457 feet in length and has a maximum storage capacity of 29 acre-feet, serving to protect the surrounding area from potential flooding events.
The dam, situated on the North Fork of the Forked Deer River, is regulated by the Tennessee Safe Dams Program and has a low hazard potential with a moderate risk rating. Although it lacks state permitting, inspection, and enforcement, the dam is regularly monitored, with the last inspection conducted in January 2020. With uncontrolled spillways and outlet gates, the dam's design and construction were funded and overseen by the Natural Resources Conservation Service, ensuring its efficacy in mitigating flood risks in the region.
Water resource and climate enthusiasts can appreciate the engineering and environmental impact of North Fork Forked Deer River Dam No. 5, as it serves as a vital infrastructure for flood control in the area. Its strategic location, design, and maintenance contribute to the overall water management efforts in Tennessee, highlighting the collaborative efforts between local government agencies and federal entities to safeguard communities from potential water-related disasters. The dam's presence underscores the importance of sustainable water resource management and the role of infrastructure in adapting to changing climate conditions for the benefit of the local ecosystem and residents.

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.
