Summary

2, also known as Grant Brook, is a critical water resource management site located in Ludlow, Vermont. This site is owned and regulated by the local government, with oversight from the Vermont Department of Environmental Conservation. The primary purpose of the dam at this site is flood risk reduction, with a focus on protecting the surrounding area from potential water-related hazards.

Constructed in 1969 by the USDA NRCS, the Earth-type dam at Jewell Brook Site No. 2 stands at a height of 70 feet and has a hydraulic height of 66 feet. With a storage capacity of 347 acre-feet, this dam plays a crucial role in managing water flow and minimizing flood risks in the region. The dam is classified as having a high hazard potential, with a fair condition assessment as of the last inspection in May 2017.

Overall, Jewell Brook Site No. 2 serves as a key component of water resource management in Windsor County, Vermont. With its strategic location and effective flood risk reduction capabilities, this site plays a vital role in safeguarding the community against water-related emergencies. As climate change continues to impact the frequency and intensity of extreme weather events, the maintenance and upkeep of this dam will be essential in ensuring the resilience of the surrounding area to potential flooding incidents.

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. 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

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, 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.
