Summary
With a primary purpose of irrigation, this Earth-type dam stands at a hydraulic height of 58 feet and a structural height of 64.5 feet, with a total length of 460 feet. The dam has a normal storage capacity of 53 acre-feet and a maximum storage of 78 acre-feet, serving a drainage area of 0.05 square miles in the TRIBLAUREL FORK stream.
Despite its low hazard potential and moderate risk assessment, Rarity Mountain has not been rated for its condition assessment. The dam operates under the jurisdiction of the state of Tennessee, with permitting, inspection, and enforcement carried out by state agencies. The dam's spillway is uncontrolled, and it has not undergone any modifications since its completion. The last inspection of Rarity Mountain took place in January 2018, with a scheduled inspection frequency of 5 years to ensure its continued safety and functionality.
Enthusiasts of water resources and climate will find Rarity Mountain to be a fascinating example of a privately owned irrigation dam in Tennessee. Its strategic location, design features, and operational aspects make it a noteworthy structure in the region. With a focus on water management for agricultural purposes, Rarity Mountain plays a crucial role in supporting local irrigation needs and contributing to the overall water resource management in the area.

Dam Data Reference
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.
