Summary
Fork Forked Deer #18, also known as North Fork Forked Deer Site 18, is a local government-owned earth dam located in Gibson County, Tennessee. Constructed in 1984 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the TRIBNO. FORK FORKED DEER stream. Standing at a structural height of 25 feet and a hydraulic height of 16 feet, it has a storage capacity of 45 acre-feet and covers a surface area of 2.2 acres.
Managed by the Tennessee Safe Dams Program, this dam has been deemed to have a significant hazard potential but is currently in satisfactory condition based on a 2019 assessment. Despite its uncontrolled spillway type, the dam's inspection frequency is set at every two years to ensure its continued safety and functionality. With a moderate risk rating, No. Fork Forked Deer #18 plays a crucial role in protecting the surrounding areas from potential flood events, highlighting the importance of proper water resource management and climate resilience efforts in the region.
As a key infrastructure piece in flood risk reduction, No. Fork Forked Deer #18 underscores the collaborative efforts between local government and regulatory agencies in maintaining the safety and integrity of water resources in Tennessee. Its presence reflects a commitment to safeguarding communities from natural disasters and underscores the ongoing need for proactive risk management measures in the face of changing climate patterns.

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.
