Lynde Brook Reservoir Dam dam
Lynde Brook Reservoir Dam
The Lynde Brook Reservoir Dam in Leicester, Massachusetts, stands as a vital structure for water supply purposes, completed in 1876. The dam, primarily of earth and buttress core type, reaches a height of 61.3 feet and has a hydraulic height of 55.6 feet, holding a maximum storage capacity of 2,880 acre-feet with a normal storage of 2,300 acre-feet. The reservoir covers a surface area of 129 acres and drains a 3.2 square mile watershed, serving as a crucial resource for the surrounding community.
Managed by the local government and regulated by the Department of Conservation and Recreation, the Lynde Brook Reservoir Dam undergoes regular inspections, with a satisfactory condition assessment as of December 2017. Despite its high hazard potential, the risk assessment rates the dam's risk as moderate (3), indicating a manageable level of risk. The dam's emergency action plan was last revised in 2007, emphasizing the importance of preparedness in the event of an unforeseen emergency.
Water resource and climate enthusiasts are drawn to the Lynde Brook Reservoir Dam not only for its historical significance and engineering marvel but also for its essential role in providing water supply to the region. With a combination of solid construction, regular inspections, and effective risk management measures, the dam stands as a critical infrastructure safeguarding the community's water resources while maintaining a balance between safety and sustainability in the face of changing climate conditions.
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 Lynde Brook Reservoir Dam
Where does the data for Lynde Brook Reservoir Dam 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.
