Windemere Lake Dam Dam
Windemere Lake Dam
Windemere Lake Dam, located in New Marlborough, Massachusetts, is a privately owned structure that serves primarily for recreational purposes. Completed in 1973, this earth dam stands at a height of 40 feet and has a hydraulic height of 30 feet. With a storage capacity of 1436 acre-feet and a normal storage level of 580 acre-feet, the dam is situated on a tributary of the Whiting River and covers a surface area of 0.25 square miles.
Managed by the Department of Conservation and Recreation in Massachusetts, Windemere Lake Dam has a low hazard potential and is deemed to be in satisfactory condition as of the last inspection in 2009. The dam features an uncontrolled spillway type and has not undergone significant modifications since its construction. Despite its moderate risk assessment score of 3, the structure is regulated and inspected by state authorities, ensuring its continued safety and functionality for nearby residents and visitors to enjoy the recreational opportunities offered by Windemere Lake.
For water resource and climate enthusiasts, Windemere Lake Dam represents a vital piece of infrastructure in Berkshire County, Massachusetts. Its careful monitoring and maintenance exemplify the importance of sustainable water management practices in the face of changing environmental conditions, making it a noteworthy landmark in the region for both its recreational and ecological significance.

About Windemere Lake Dam
Where does the data for Windemere Lake 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 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 below 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.

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.
