Langwater Pond Dam dam
Langwater Pond Dam
Langwater Pond Dam in Easton, Massachusetts, is a picturesque structure nestled amidst the Whitman and Queset Brooks. Managed by the Department of Conservation and Recreation, this masonry dam primarily serves as a recreational spot, offering a serene escape for water resource and climate enthusiasts. With a height of 11 feet and a storage capacity of 90 acre-feet, the dam provides a tranquil surface area of 8.34 acres for visitors to enjoy.
Despite its significant hazard potential, Langwater Pond Dam has been deemed structurally sound, with a satisfactory condition assessment as of August 2012. The dam's spillway, classified as uncontrolled, adds to the charm of the area while also serving a crucial safety function. While the last inspection was conducted in 2012, with a scheduled frequency of every 5 years, the risk assessment remains at a moderate level, indicating a need for continued monitoring and maintenance to ensure the safety of the surrounding community.
The presence of Langwater Pond Dam not only enhances the natural beauty of the region but also underscores the importance of proper water resource management. Its role in providing recreational opportunities while also safeguarding against potential hazards highlights the delicate balance between human enjoyment and environmental protection. As climate change continues to impact water resources, structures like Langwater Pond Dam serve as vital components in maintaining the resilience of our ecosystems.

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 Langwater Pond Dam
Where does the data for Langwater Pond 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 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.
