Summary
23, located in Trenton, Gibson County, Tennessee, was completed in 1985 by the USDA NRCS. The dam, primarily owned by the local government, serves the purpose of flood risk reduction along the North Fork Forked Deer River. Standing at a height of 24.4 feet with a hydraulic height of 24 feet, the earth dam spans 288 feet in length and has a storage capacity of 38.5 acre-feet.
Despite being classified as having a low hazard potential, the dam's risk assessment is considered moderate (3), indicating a need for ongoing risk management measures. The structure, made of stone core and soil foundation, features an uncontrolled spillway and outlet gates. With a drainage area of 0.14 square miles, the dam has a maximum discharge capacity of 483 cubic feet per second. While the condition assessment is currently not rated, the dam's emergency action plan status and inundation maps are not updated, highlighting areas for improvement in emergency preparedness and risk mitigation for this vital flood control structure.

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.
