Tremont Mill Pond dam
Tremont Mill Pond
Tremont Mill Pond, also known as Tremont Iron Works, is a historic site located in Wareham, Massachusetts. Built in 1845, this earth dam stands at 15 feet high and spans a length of 1200 feet, creating a reservoir with a storage capacity of 340 acre-feet. The pond serves multiple purposes including hydroelectric power generation, fire protection, irrigation, and recreation.
Managed by the Federal Energy Regulatory Commission, Tremont Mill Pond has a spillway width of 24 feet and a maximum discharge capacity of 1555 cubic feet per second. Despite its high hazard potential, the condition assessment of the dam is currently not available. The reservoir covers an area of 57 acres and has a drainage area of 53 square miles, providing vital water resources for the surrounding area.
With a very high risk rating and a lack of updated emergency action plans, there is a need for increased monitoring and risk management measures at Tremont Mill Pond. As a significant water resource in Plymouth County, Massachusetts, this site holds historical and environmental importance for the region. Climate and water resource enthusiasts will find Tremont Mill Pond to be a unique blend of history, hydroelectric power, and recreational opportunities set against the backdrop of the Weweantic River.
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 Tremont Mill Pond
Where does the data for Tremont Mill Pond 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.
