Number One Pond Dam dam
Number One Pond Dam
Number One Pond Dam in Sutton, Massachusetts, is a privately owned structure regulated by the Department of Conservation and Recreation. The dam, classified as a buttress core type with a height of 11 feet, serves the primary purpose of water storage. With a maximum storage capacity of 56 acre-feet and a normal storage level of 24 acre-feet, the dam plays a crucial role in managing water resources in the area.
Despite being assessed as in fair condition during the last inspection in March 2017, Number One Pond Dam has been deemed to have a significant hazard potential. With a moderate risk assessment rating, measures for risk management and emergency action plans are crucial for ensuring the safety and functionality of the dam. Additionally, the dam's uncontrolled spillway type and location in Worcester County highlight the importance of regular inspections and maintenance to prevent potential risks and mitigate any adverse impacts on the surrounding environment and communities.
As water resource and climate enthusiasts, understanding the role and condition of dams like Number One Pond Dam is essential for ensuring sustainable water management practices. With its significant hazard potential and moderate risk assessment, proactive measures and emergency preparedness are key to maintaining the dam's integrity and safeguarding the local ecosystem and residents from potential harm. Continued monitoring and adherence to regulatory standards by the Department of Conservation and Recreation are vital for the long-term resilience of Number One Pond Dam and its critical role in water resource management.
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 Number One Pond Dam
Where does the data for Number One 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.
