Hoppin Hill Reservoir Dam dam
Hoppin Hill Reservoir Dam
Located in North Attleborough, Massachusetts, the Hoppin Hill Reservoir Dam stands as a vital piece of infrastructure for the region's water supply. Completed in 1910, this earth dam spans 1100 feet and reaches a height of 27 feet, with a primary purpose of water supply. The reservoir created by the dam has a storage capacity of 441 acre-feet and serves as a crucial resource for the surrounding community.
Managed by the Department of Conservation and Recreation, the Hoppin Hill Reservoir Dam is subject to state regulations, inspections, and enforcement to ensure its safety and reliability. With a high hazard potential but a satisfactory condition assessment, the dam poses a moderate risk, prompting regular inspections and emergency action plans to be in place. Despite its age, the dam continues to play a key role in water resource management in Bristol County, Massachusetts.
Surrounded by the tranquil waters of the Seven Mile River, the Hoppin Hill Reservoir Dam is not only a functional structure but also a scenic attraction in the area. With its buttress core design and uncontrolled spillway, the dam exemplifies the intersection of engineering ingenuity and environmental stewardship. For water resource and climate enthusiasts, the Hoppin Hill Reservoir Dam serves as a reminder of the importance of sustainable infrastructure in ensuring the availability of essential resources for generations to come.

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.
Plan around the weather

About Hoppin Hill Reservoir Dam
Where does the data for Hoppin Hill Reservoir 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 High 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.
