Tetreault dam
Tetreault
Tetreault is a state-regulated Earth dam located in Addison, Vermont, specifically on the EAST BRANCH DEAD CREEK-TR river or stream. Built in 1957 by the designers Haley & Ward, this dam serves as a Fish and Wildlife Pond with a storage capacity of 100 acre-feet. The dam stands at a height of 17 feet and has a length of 215 feet, with a surface area of 9 acres and a drainage area of 1.2 square miles.
Even though Tetreault has a low hazard potential and is not currently rated for its condition, it is subject to regular state inspections, permitting, and enforcement by the Vermont Department of Environmental Conservation. The dam's last inspection was conducted in May 2004, with a frequency of every 10 years. While there is no Emergency Action Plan (EAP) in place, there are no associated locks, spillways, or outlet gates present, indicating a simpler structure in terms of hydraulic components.
For water resource and climate enthusiasts, Tetreault presents an interesting case study in dam infrastructure, highlighting the importance of state regulation and inspection in ensuring the safety and functionality of water retention structures. The dam's primary purpose of supporting fish and wildlife populations underscores the critical role that such structures play in ecological conservation efforts. With its location in a scenic area of Vermont and its relatively low risk profile, Tetreault serves as a reminder of the balance between harnessing water resources for human and environmental benefit while mitigating potential hazards.

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 Tetreault
Where does the data for Tetreault 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.
