Memorial Pond Dam dam
Memorial Pond Dam
Memorial Pond Dam, located in Walpole, Massachusetts, was completed in 2004 and serves as a recreational water resource on Diamond Brook. The earth-type dam stands at a height of 11 feet with a hydraulic height of 8.5 feet, providing a storage capacity of 140 acre-feet. The dam's primary purpose is for recreation, offering a surface area of 9 acres and a normal storage capacity of 12 acre-feet.
Managed by the Department of Conservation and Recreation in Massachusetts, Memorial Pond Dam is state-regulated and undergoes regular inspections to ensure its structural integrity. The dam has a significant hazard potential but is currently assessed to be in satisfactory condition. In case of emergencies, the dam is equipped with an Emergency Action Plan, although details on its preparation and guidelines meeting are not specified in the data.
For water resource and climate enthusiasts, Memorial Pond Dam presents an intriguing case study of a local government-owned structure that provides both recreational opportunities and water storage capabilities. With its moderate risk assessment and significant hazard potential, the dam serves as a focal point for ongoing risk management efforts to ensure the safety and sustainability of this vital water resource in Norfolk County, Massachusetts.

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 Memorial Pond Dam
Where does the data for Memorial 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.
