Summary
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
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.
