Summary
Built in 1963, this Earth-type dam stands at a structural height of 24.4 feet, with a hydraulic height of 20.3 feet. It is situated on the WEST BEAVER CREEK CANAL, with a drainage area of 0.04 square miles and a surface area of 6.7 acres. The dam has a storage capacity of 83 acre-feet, with a normal storage level of 55 acre-feet.
Despite being classified as having a low hazard potential, Drewry has a moderate risk assessment. The dam features an uncontrolled spillway and is not regulated by the state. The last inspection of the structure was conducted on June 10, 2019, with a frequency of every 5 years. The risk management measures and emergency action plans for Drewry are currently not rated or assessed, indicating potential areas for improvement in terms of preparedness and response protocols.
For water resource and climate enthusiasts, Drewry presents an intriguing case study in dam infrastructure management and risk assessment. With its historical significance dating back to the early 1960s, the dam continues to serve its purpose in regulating water flow along the West Beaver Creek Canal. The moderate risk assessment highlights the importance of ongoing monitoring and evaluation to ensure the safety and functionality of this critical water resource infrastructure in Tennessee.

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.
