Summary
Fork Forked Deer #8 is a vital earth dam located in Gibson, Tennessee, designed by USDA NRCS - SAM DARNEL and completed in 1998. This dam, managed by the Tennessee Safe Dams Program, serves a variety of purposes beyond flood control, with a hydraulic height of 13.9 feet and a structural height of 19.8 feet. It has a low hazard potential and was deemed to be in satisfactory condition during its last assessment in August 2017.
The dam's reservoir has a maximum storage capacity of 57 acre-feet and a normal storage level of 21 acre-feet, covering a surface area of 4.3 acres. With a drainage area of 0.18 square miles, the dam plays a crucial role in managing water resources in the region. Despite its low hazard potential, the dam undergoes regular inspections and is regulated, permitted, and inspected by the state to ensure its safety and functionality.
Located in the Memphis District, No. Fork Forked Deer #8 is a significant structure owned by the local government and stands as a testament to effective water resource management in Tennessee. With its moderate risk assessment rating and satisfactory condition, this dam remains a key asset for water resource and climate enthusiasts in the area.

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.
