Summary
The dam stands at 35 feet tall with a hydraulic height of 20 feet and a length of 200 feet, providing a storage capacity of 46 acre-feet. Despite being unlisted for foundations, the dam has a low hazard potential and is categorized as having a moderate risk level.
Located within the Nashville District of the US Army Corps of Engineers, Farnham Lake Dam has an uncontrolled spillway and outlet gates. The last inspection conducted in October 2012 rated the dam's condition as "Not Rated," and it has an inspection frequency of 5 years. While the dam is not regulated by the state, it is subject to periodic inspections to ensure its safety and functionality. The risk level of the dam is considered moderate, indicating a need for ongoing monitoring and risk management measures.
Water resource and climate enthusiasts may find Farnham Lake Dam an intriguing site for its recreational purposes and unique earth dam construction. With its moderate risk level and low hazard potential, the dam serves as a valuable asset for water storage and recreational activities in the region. Continuous monitoring and inspection are essential to ensure the safety and integrity of the dam for the surrounding community and the environment.

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.
