Summary

Fork Forked Deer #37 is a locally owned Earth dam located in Gibson, Tennessee, with a primary purpose of flood risk reduction. Built in 1996 by the USDA NRCS, this dam stands at a structural height of 26.1 feet and has a hydraulic height of 20.8 feet. With a storage capacity of 27 acre-feet and a drainage area of 0.09 square miles, this dam plays a crucial role in mitigating flood risks in the area.

Managed by the Tennessee Safe Dams Program, No. Fork Forked Deer #37 has a low hazard potential and is currently in satisfactory condition, as assessed during the last inspection in July 2020. With a moderate risk assessment rating of 3, this dam meets state permitting, inspection, and enforcement requirements, ensuring its functionality and safety. Despite its uncontrolled spillway type, this dam serves as a vital infrastructure for water resource management in the region and contributes to the overall resilience of the community against potential flooding events.

For water resource and climate enthusiasts, No. Fork Forked Deer #37 presents an intriguing case study of local government ownership and management of a flood risk reduction structure. With its well-maintained condition and adherence to state regulations, this dam exemplifies the importance of proactive risk management in safeguarding communities against the impacts of extreme weather events. Its role in protecting the surrounding area from potential inundation showcases the critical intersection between infrastructure, water resources, and climate resilience in ensuring the safety and security of residents in flood-prone regions like Gibson, Tennessee.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
