Tillis #2 dam
Tillis #2
Tillis #2, located in Cheatham, Tennessee, is a privately owned earth dam completed in 1985 for fire protection, stock, or small fish pond purposes. With a hydraulic height of 22 feet and a structural height of 25 feet, the dam has a storage capacity of 90 acre-feet and a surface area of 7.6 acres. Situated on TribSycamore Creek, the dam is under the jurisdiction of the Nashville District but is not regulated by the state of Tennessee.
Despite being rated as having a low hazard potential and a moderate risk assessment, Tillis #2 has not been given a condition assessment. The dam, equipped with an uncontrolled spillway, has a last inspection date of May 27, 2016, with an inspection frequency of 5 years. The emergency action plan (EAP) status, including preparedness, guidelines compliance, and risk management measures, is currently unspecified. While the dam does not have any associated lock structures, it serves as a crucial resource for fire protection and agricultural purposes in the region.
Overall, Tillis #2 is an essential water resource in Cheatham, Tennessee, providing fire protection and stock water storage. With a moderate risk assessment and low hazard potential, the dam's condition assessment is yet to be rated. As an earth dam with a storage capacity of 90 acre-feet, Tillis #2 remains a vital component of the local water management infrastructure along TribSycamore Creek.

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 Tillis #2
Where does the data for Tillis #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 Low 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.
