Summary
Constructed in 1955, this dam stands at a hydraulic height of 27.5 feet and a structural height of 32.5 feet, with a total length of 391 feet. It has a normal storage capacity of 65 acre-feet and a maximum storage of 90 acre-feet, covering a surface area of 4.5 acres and draining an area of 0.08 square miles.
Despite its relatively small size, Collins #3 poses a high hazard potential due to its uncontrolled spillway type. The dam has not been rated for its condition assessment, but it undergoes inspections every five years to ensure its integrity. While the risk assessment for this structure is moderate, no specific risk management measures or emergency action plans have been reported. The dam is not regulated by the state and does not have associated locks or outlet gates.
For water resource and climate enthusiasts, Collins #3 offers a glimpse into the diverse landscape of dams in Tennessee. Its location along the TribIndian Creek and its high hazard potential underscore the importance of proper maintenance and monitoring of such structures to prevent potential risks to surrounding communities and ecosystems. As an Earth dam with a history dating back to the mid-20th century, Collins #3 serves as a reminder of the ongoing need for effective dam management and emergency preparedness in the face of changing environmental conditions.

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.
