Mill Pond Dam dam
Mill Pond Dam
Mill Pond Dam, located in Wareham, Massachusetts, is a state-owned structure on the Agawam River with a primary purpose of recreation. Built in 1850, this Earth dam stands at a height of 16.5 feet and has a hydraulic height of 15 feet, providing a storage capacity of 1,768 acre-feet. The dam, with a length of 285 feet, creates a surface area of 146 acres and serves a drainage area of 11.4 square miles.
Despite its historical significance and recreational value, Mill Pond Dam poses a high hazard potential and has been assessed to be in poor condition, with a moderate risk rating. The last inspection in November 2019 highlighted the need for improvement and the dam's emergency action plan is yet to be updated. The state regulatory agency, the Department of Conservation and Recreation, oversees the permitting, inspection, and enforcement of this dam to ensure public safety and environmental protection.
For water resource and climate enthusiasts, Mill Pond Dam serves as a focal point of interest due to its historical roots, recreational opportunities, and the challenges it faces in terms of safety and maintenance. As discussions around dam safety and resilience continue, this structure on the Agawam River showcases the importance of proper management and risk assessment in safeguarding our water resources amidst changing climate conditions.

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 Mill Pond Dam
Where does the data for Mill 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 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.
