Summary
Completed in 1955, this structure stands at a hydraulic height of 39.5 feet and a structural height of 43 feet, with a length of 422 feet. It has a storage capacity of 410 acre-feet, with a normal storage level of 17 acre-feet. The dam is situated on the tributary of Indian Creek, serving as a vital reservoir for water resource management in the region.
Despite being privately owned, Collins #1 has a high hazard potential, with a moderate risk assessment rating. While the dam's condition assessment is currently listed as "Not Rated," it undergoes inspections every five years to ensure its structural integrity and safety. The spillway type is uncontrolled, with no outlet gates specified. The dam is part of the Nashville District and is not regulated by the state or federal agencies, highlighting its importance in local water resource management efforts.
Water resource and climate enthusiasts will find Collins #1 to be a fascinating structure in the Tennessee landscape, serving as a key component in the region's water supply infrastructure. With its high hazard potential and moderate risk assessment, the dam presents both challenges and opportunities for effective risk management and emergency preparedness. As a privately owned earth dam with significant storage capacity, Collins #1 plays a crucial role in maintaining water security and sustainability in Davidson County and beyond.

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.
