Summary
13a is a significant earth dam designed by USDA NRCS for flood risk reduction. Completed in 1999, this dam stands at 21.9 feet high with a hydraulic height of 21 feet and a structural height of 25 feet. With a storage capacity of 90 acre-feet and a maximum discharge of 68 cubic feet per second, this dam plays a crucial role in managing water levels and mitigating flood risks in the area.
The dam, primarily owned by the local government, serves as a key infrastructure for the region's water resource management. Its uncontrolled spillway and outlet gates ensure effective water flow control during heavy rainfall events. Despite its significant hazard potential, the dam is rated as having a moderate risk level (3) and has not undergone a recent condition assessment. While the dam lacks certain emergency preparedness measures such as an Emergency Action Plan (EAP), it remains a vital structure for safeguarding the community against potential flooding.
With its stone core and soil foundation, North Fork Forked Deer River Dam No. 13a exemplifies the collaborative efforts of the USDA NRCS in construction, design, and funding. Its strategic location along the Tr- Forked River N Fork, within the Gibson County of Tennessee, underscores its importance in protecting the surrounding areas from floodwaters. As an integral component of the local water management system, this dam stands as a testament to the commitment to sustainable water resource practices and climate resilience 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.
