Summary
Fork Forked Deer #7, also known as North Fork Forked Deer Site 7, is a local government-owned earth dam located in Gibson County, Tennessee. Designed by the USDA NRCS and completed in 1986, this dam serves the primary purpose of flood risk reduction along the TRIB NO. FORK FORKED DEER stream. With a hydraulic height of 13.5 feet and a structural height of 18.5 feet, this dam has a NID storage capacity of 82 acre-feet and a normal storage capacity of 31 acre-feet, covering a surface area of 7.5 acres and draining a 0.29 square mile watershed.
The dam has a low hazard potential and a satisfactory condition assessment as of the last inspection in June 2018, with a moderate risk assessment rating. While there are no outlet gates or associated structures, the dam features an uncontrolled spillway type. The Tennessee Safe Dams Program regulates this dam, ensuring state permitting, inspection, and enforcement are in place to maintain its safety and functionality. With its strategic location and design, No. Fork Forked Deer #7 stands as a vital infrastructure contributing to the water resource management and climate resilience efforts in the region.

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.
