Summary
Designed by the Natural Resources Conservation Service, this earth dam stands at a height of 21 feet and has a maximum storage capacity of 83 acre-feet. With a surface area of 12 acres, the dam serves as a popular spot for outdoor activities and relaxation in Franklin County.
Although the Alston Lake Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, it is important to note that the risk assessment for this dam is categorized as moderate. With uncontrolled spillways and outlet gates, there is a moderate level of risk associated with this structure. As it does not fall under state jurisdiction for regulation or inspection, the responsibility for maintenance and safety falls on the private owner.
For water resource and climate enthusiasts, the Alston Lake Dam presents an interesting case study in private dam ownership and recreational water management. With its peaceful location and moderate risk assessment, this dam serves as a reminder of the importance of regular inspection and maintenance to ensure the safety of both the structure and the surrounding environment.

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.
