Summary
Built in 1957 by designers Haley & Ward, this earth dam stands at a height of 10 feet with a hydraulic height of 11 feet and a structural height of 19 feet. The primary purpose of Brilyea East is to serve as a Fish and Wildlife Pond, providing important habitat for local flora and fauna. With a storage capacity of 1450 acre-feet and a surface area of 126 acres, this dam plays a crucial role in supporting the surrounding ecosystem.
Despite being classified as having a low hazard potential, Brilyea East is regularly inspected by the Vermont Department of Environmental Conservation to ensure its structural integrity and safety. The dam is reported to be in fair condition as of its last assessment in July 2015. With a drainage area of 23 square miles, Brilyea East contributes to the overall water management of the region and provides opportunities for recreational activities such as fishing and wildlife observation. As a key component of the local water resource infrastructure, this dam serves as a testament to the importance of sustainable water management practices in mitigating the impacts of climate change on water resources.
As a vital component of the water resource system in Addison, Vermont, Brilyea East stands as a testament to the commitment of the state in maintaining and regulating its water infrastructure. With its historical significance and ecological importance, this dam serves not only as a protective barrier but also as a valuable resource for the community.

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.
