Strangmans Pond Dam dam
Strangmans Pond Dam
Strangmans Pond Dam, located in Gloucester, Massachusetts, was completed in 1884 and serves as a vital water supply structure in the region. This earth dam, with a height of 10 feet and a hydraulic height of 3 feet, impounds a reservoir with a storage capacity of 920 acre-feet. The dam is owned and regulated by a private entity but falls under the jurisdiction of the Department of Conservation and Recreation in Massachusetts.
Despite its historical significance and crucial role in water supply, Strangmans Pond Dam poses a high hazard potential due to its poor condition assessment. The dam lacks a spillway and emergency action plan, raising concerns about its ability to withstand extreme weather events or sudden influxes of water. With a risk assessment rating of High (2), stakeholders must prioritize maintenance and risk management measures to ensure the safety and integrity of this essential infrastructure.
Water resource and climate enthusiasts monitoring the Strangmans Pond Dam should be aware of its location on a tributary of the Annisquam River and the potential implications of its conditions on the surrounding ecosystem. As inspections are conducted every 10 years, ongoing efforts to address the dam's deficiencies and implement emergency preparedness measures are critical to safeguarding both the water supply and the community in the face of changing climate patterns and increasing environmental risks.

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 Strangmans Pond Dam
Where does the data for Strangmans 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.
