Jewell Brook Site No. 1 dam
Jewell Brook Site No. 1
Jewell Brook Site No. 1, also known as Upper Jewell Brook, is a critical flood risk reduction structure located in Ludlow, Vermont. Constructed in 1969 by the USDA NRCS, this earth dam stands at a height of 58 feet, with a hydraulic height of 57 feet and a structural height of 69 feet. With a storage capacity of 521 acre-feet and a drainage area of 2.09 square miles, this dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the DEC and regulated by the state of Vermont, Jewell Brook Site No. 1 has a high hazard potential and is classified as being in fair condition. Despite its moderate risk assessment rating, this dam serves as a vital piece of infrastructure for flood control in the region. With its uncontrolled spillway and stone core, this structure is designed to withstand and mitigate the impact of extreme weather events, ensuring the safety of local residents and the stability of the surrounding environment.
As a key component of the flood risk reduction system in Windsor County, Vermont, Jewell Brook Site No. 1 plays a crucial role in protecting the community from potential disasters. With its history of successful operation and ongoing regulatory oversight, this dam stands as a testament to the importance of water resource management and climate resilience efforts in the face of changing environmental conditions. It serves as a vital example of how proactive measures can help mitigate the impacts of climate change on our water resources and infrastructure.

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 Jewell Brook Site No. 1
Where does the data for Jewell Brook Site No. 1 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 High 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.
