Summary
Built in 1977 by the USDA NRCS, this private-owned earth dam stands at a height of 14 feet and spans 550 feet along TR-Thompson Creek. The primary purpose of this dam is to serve as a fish and wildlife pond, while also providing fire protection, stock, and recreation opportunities.
With a low hazard potential and a moderate risk assessment rating, Evans Dam has a storage capacity of 79 acre-feet, with a normal storage level of 36 acre-feet. The dam features an uncontrolled spillway with a width of 100 feet, allowing for a maximum discharge rate of 1500 cubic feet per second. While the dam has not been rated for its current condition, it has not undergone any recent modifications and is not under state jurisdiction.
For water resource and climate enthusiasts, Evans Dam offers a fascinating example of a privately-owned structure designed to support wildlife preservation and recreational activities. Its location in the picturesque landscape of Montgomery County, Alabama, along with its historical significance as part of the local ecosystem, makes it a valuable asset for both conservationists and outdoor enthusiasts alike.

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.
