Rattle & Snap #21 dam
Rattle & Snap #21
Rattle & Snap #21 is a privately owned dam located on TribSugar Creek in Maury, Tennessee. Built in 1980, this earth dam stands at a structural height of 55.6 feet with a hydraulic height of 27.7 feet, providing a storage capacity of 4,600 acre-feet of water. The dam has a significant hazard potential but is currently assessed to be in satisfactory condition as of the last inspection in June 2020.
Managed by the Tennessee Safe Dams Program, Rattle & Snap #21 is regulated, permitted, inspected, and enforced by the state of Tennessee. Despite its moderate risk rating, there are no emergency action plans (EAP) in place, and the dam lacks inundation maps and updated emergency contacts. While the dam does not have outlet gates or locks, it features an uncontrolled spillway and covers a drainage area of 0.04 square miles. The dam's purpose and associated structures are not specified, but its primary function is known to be for water resource management.
Overall, Rattle & Snap #21 is a crucial water resource infrastructure in the Nashville District, providing storage and flood control benefits for the local community. Its location on TribSugar Creek and its ownership by a private entity highlight the importance of maintaining and monitoring the dam to ensure its continued safety and effectiveness in managing water resources in the region. For water resource and climate enthusiasts, understanding the details of this dam's construction, storage capacity, and regulatory oversight offers valuable insights into the intersection of infrastructure, safety, and environmental stewardship.
Dam data reference
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 Rattle & Snap #21
Where does the data for Rattle & Snap #21 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 Significant 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.
