Reservoir #6 Dam dam
Reservoir #6 Dam
Reservoir #6 Dam, located in Sutton, Massachusetts, is a concrete dam built in 1905 primarily for water supply purposes. Managed by a private owner, this dam is regulated by the Department of Conservation and Recreation in Massachusetts. Standing at a height of 15.5 feet and with a hydraulic height of 13 feet, Reservoir #6 Dam serves as a crucial structure in the tributary of Mumford River, providing a storage capacity of 157 acre-feet and covering a surface area of 0.02 square miles.
Despite its age, Reservoir #6 Dam is assessed to be in fair condition with low hazard potential, as indicated by the most recent inspection in October 2009. The dam has a moderate risk rating and an inspection frequency of 10 years. With a spillway type of uncontrolled, the dam has no outlet gates and is not associated with any other structures. While the dam has not undergone any modifications in recent years, it continues to play a vital role in water resource management in Worcester County, Massachusetts.
For water resource and climate enthusiasts, Reservoir #6 Dam stands as a historic and functional piece of infrastructure that contributes to the water supply and regulatory framework in the region. Its presence highlights the importance of maintaining and monitoring dams for both safety and sustainability, ensuring the continued availability of water resources for the community.

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 Reservoir #6 Dam
Where does the data for Reservoir #6 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 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.
