Caledonia Creek #3 dam
Caledonia Creek #3
Caledonia Creek #3 is a state-regulated dam located in Henry, Tennessee, along the Caledonia Creek. This Earth dam, completed in 1991, stands at a height of 36 feet with a hydraulic height of 24 feet. It has a storage capacity of 3,740 acre-feet and serves a drainage area of 4.18 square miles. The dam has a significant hazard potential and is regularly inspected by the Tennessee Safe Dams Program, with the last assessment conducted in September 2019.
Despite its satisfactory condition assessment, Caledonia Creek #3 poses a moderate risk level (3) and lacks certain emergency preparedness measures such as an Emergency Action Plan (EAP) and inundation maps. The dam does not have outlet gates and features an uncontrolled spillway. The dam's primary purpose and associated structures are not specified, suggesting that it may be used for flood control or water supply management. The dam is owned by the state of Tennessee and falls under the regulatory oversight of the Tennessee Safe Dams Program, ensuring that it meets state inspection and enforcement standards.
For water resource and climate enthusiasts, Caledonia Creek #3 presents an intriguing case study of a state-regulated dam with a significant hazard potential and moderate risk assessment. The dam's location along the Caledonia Creek and its role in managing water resources in Henry County, Tennessee, highlight the importance of maintaining and monitoring critical infrastructure for water supply and flood control purposes. The dam's design, construction, and storage capacity provide valuable insights into the management of water resources in the region, while its regulatory oversight by the Tennessee Safe Dams Program underscores the commitment to ensuring the safety and integrity of dams in the state.

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 Caledonia Creek #3
Where does the data for Caledonia Creek #3 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.
