Knapp Brook Site No. 2 dam
Knapp Brook Site No. 2
Knapp Brook Site No. 2, also known as Knapp Pond Site No. 2, is a state-owned recreation area located in Cavendish, Vermont. The dam, completed in 1961 by designer Haley & Ward, stands at a height of 22 feet and is primarily used for recreational purposes. The dam's primary purpose is to provide a surface area of 35 acres for activities such as fishing, boating, and wildlife observation.
This significant earth dam on Knapp Brook has a storage capacity of 623 acre-feet and serves as a vital water resource for the surrounding area. With a fair condition assessment as of August 2019, the dam is regularly inspected by the Vermont Department of Environmental Conservation (DEC) to ensure its structural integrity and compliance with state regulations. It is considered to have a significant hazard potential due to its location and the population at risk downstream in the event of a breach.
Despite its proximity to residential areas, Knapp Brook Site No. 2 provides a peaceful retreat for outdoor enthusiasts and serves as an important water resource for the community. With its picturesque setting and recreational opportunities, this dam on Knapp Brook is a valuable asset for both water resource and climate enthusiasts in Windsor County, Vermont.
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 Knapp Brook Site No. 2
Where does the data for Knapp Brook Site No. 2 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 Significant 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.
