Arnold Pond Dam dam
Arnold Pond Dam
Arnold Pond Dam, located in Sutton, Massachusetts, is a state-owned structure with a primary purpose of recreation. The dam, completed in 1900, stands at a height of 14 feet and has a hydraulic height of 5.6 feet. It spans 80 feet in length and has a storage capacity of 50 acre-feet, with a normal storage level of 27 acre-feet. The dam is situated on Singletary Brook and serves as a recreational space for water resource and climate enthusiasts in the Worcester County area.
Despite its low hazard potential, Arnold Pond Dam is currently in poor condition, as assessed in 2016. The dam is of gravity type with a buttress core, and its spillway is uncontrolled. The inspection frequency is every 10 years, with the last inspection conducted in May 2016. While the risk assessment is moderate, efforts may be needed to improve the dam's condition and ensure the safety of the surrounding area.
Managed by the Department of Conservation and Recreation, Arnold Pond Dam is under state jurisdiction and regulation. While the dam provides recreational opportunities and contributes to the local environment, its poor condition and moderate risk level highlight the importance of ongoing maintenance and risk management measures. As water resource and climate enthusiasts continue to enjoy the area, it is essential to prioritize the safety and sustainability of Arnold Pond Dam for future generations to appreciate.

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 Arnold Pond Dam
Where does the data for Arnold 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 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.
