Brilyea East dam
Brilyea East
Brilyea East is a state-regulated dam located in Addison, Vermont, along the East Branch Dead Creek. 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. By ensuring the proper maintenance and operation of dams like Brilyea East, water resource and climate enthusiasts can contribute to the preservation of our natural environment and the sustainability of our water supply for future generations.
Dam data reference
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.
- 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.
- 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.
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, environmental 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.

About Brilyea East
Where does the data for Brilyea East come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
