Summary

This reservoir serves a primary purpose of hydroelectric power generation, with a dam type classified as Earth and a height of 9 feet. Completed in 1918, the dam has a storage capacity of 7,000 acre-feet and covers a surface area of 812 acres, making it a significant water resource in Essex County.

With a low hazard potential and a condition assessment of "Not Rated," Great Averill Pond is an important asset for both hydroelectric production and recreational activities. The dam's structure, primarily made of stone core supported by rock and soil foundations, contributes to its reliability and longevity. The reservoir's location in the New England District further underscores its importance in the regional water management system.

Despite not being regulated by the state, Great Averill Pond remains a key feature in Vermont's water infrastructure. As a valuable resource for both energy production and outdoor recreation, this reservoir exemplifies the intersection of water resource management and climate-friendly practices. Its history, design, and purpose make it a noteworthy site for water resource and climate enthusiasts alike.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
