Summary
Fork Forked Deer #13a is a flood risk reduction dam located in Gibson, Tennessee, designed by USDA NRCS and completed in 1999. This earth dam stands at a hydraulic height of 14.3 feet and a structural height of 21.8 feet, with a total length of 420 feet and a storage capacity of 87 acre-feet. Situated on the TRIBNO. FORK FORKED DEER river or stream, this structure is state-regulated by the TENNESSEE SAFE DAMS PROGRAM, with inspection, permitting, and enforcement processes in place to ensure its safety and functionality.
The dam's primary purpose is flood risk reduction, serving to protect the surrounding area from potential inundation. With a significant hazard potential and a satisfactory condition assessment as of July 2019, this structure plays a crucial role in managing water resources and mitigating the impacts of extreme weather events in the region. Despite its moderate risk level, the dam's design and functionality meet regulatory guidelines, highlighting its importance in safeguarding the community and supporting climate resilience efforts.
Managed by the local government and situated within the Memphis District, No. Fork Forked Deer #13a is a key infrastructure asset in the area, contributing to water resource management and climate adaptation strategies. With ongoing inspections and a focus on risk management measures, this dam exemplifies the intersection of water resources and climate resilience, showcasing the importance of proactive infrastructure planning in the face of changing environmental conditions.

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.
