Summary
Built in 1955, this dam stands at a structural height of 25 feet with a hydraulic height of 10 feet, serving the purpose of controlling the flow of the Tribindian Creek. With a normal storage capacity of 10 acre-feet and a maximum storage capacity of 60 acre-feet, this dam covers a surface area of 2 acres and has a drainage area of 0.22 square miles.
Despite its high hazard potential, Collins #2 has not been rated for its condition assessment as of yet. The dam, which is uncontrolled by a spillway, has not undergone any modifications in recent years and does not have any outlet gates installed. The last inspection was conducted in February 2019, with a scheduled inspection frequency of every 5 years. While the risk assessment for this dam is considered moderate, there are currently no detailed risk management measures or emergency action plans in place.
Water resource and climate enthusiasts may find Collins #2 an intriguing structure to study, given its historical significance and potential impact on the surrounding area. As a privately owned dam with no state regulation or permitting requirements, its management and maintenance raise questions about the overall safety and resilience of such infrastructure in the face of changing weather patterns and hydrological conditions. Further research and monitoring of Collins #2 could provide valuable insights into the intersection of water resource management, climate adaptation, and dam safety in Tennessee.

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.
