Summary
Built in 1976 by CE Associates, this earth dam stands at a height of 19 feet and has a storage capacity of 70 acre-feet, primarily serving recreational purposes. The dam is under the jurisdiction of the Vermont Department of Environmental Conservation and is regulated, permitted, inspected, and enforced by state agencies to ensure safety and compliance.
Despite being categorized as having a low hazard potential, Callery has not been recently assessed for its condition. The last inspection conducted in 1978 reported that the dam was not rated in terms of its condition. It is important for water resource and climate enthusiasts to monitor the maintenance and assessment of structures like Callery to ensure their continued safety and effectiveness in managing water resources.
As an earth dam with stone core and rock and soil foundations, Callery plays a crucial role in managing water flow and storage in the region. With its location in Addison County, Vermont, this dam contributes to the recreational activities and water management of the area. However, as the last inspection was conducted decades ago, there is a need for updated assessments and risk management measures to maintain the integrity and safety of this important infrastructure.

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.
