Collins #2 dam
Collins #2
Collins #2 is a privately owned earth dam located in Davidson County, Tennessee, specifically in the city of Dozier Hollow. 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
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Collins #2
Where does the data for Collins #2 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
