Summary
Albans South Reservoir, also known as St. Albans Lower Reservoir, is a gravity-type dam located in Fairfax, Vermont. Completed in 1910, this reservoir serves as a vital water supply source for the surrounding area, with a storage capacity of 530 acre-feet and a surface area of 26 acres. The dam stands at a height of 26 feet and stretches 1950 feet in length, providing essential water resources for the community.
Managed by the local government and regulated by the Vermont Department of Environmental Conservation (DEC), the St. Albans South Reservoir plays a crucial role in water supply management. With a high hazard potential and fair condition assessment, regular inspections ensure the safety and reliability of the dam. While there are no associated structures or federal agency involvements, the dam remains a key infrastructure for water resource and climate enthusiasts in Franklin County, Vermont.
As a significant part of the Mill River system and situated in a picturesque location, the St. Albans South Reservoir offers a unique opportunity for visitors to appreciate the intersection of water resource management and environmental conservation. With its historical significance and impact on the local community, this gravity dam stands as a testament to the importance of sustainable water supply infrastructure in the face of changing climate conditions.

Dam Data Reference
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.
