Stedman Marsh Dam dam
Stedman Marsh Dam
Stedman Marsh Dam, located in Monterey, Berkshire County, Massachusetts, is a privately-owned concrete dam primarily used for water supply purposes. Standing at a height of 8 feet with a hydraulic height of 6 feet, this dam has a storage capacity of 181.5 acre-feet and covers a surface area of 30 acres. The dam, built with a buttress core type, serves as a crucial water resource infrastructure in the region.
Despite its importance, Stedman Marsh Dam has a poor condition assessment and a low hazard potential, indicating the need for maintenance and upgrades to ensure its safety and functionality. The dam is regulated by the Department of Conservation and Recreation in Massachusetts, with state permitting, inspection, and enforcement in place. The last inspection in March 2017 revealed its poor condition, highlighting the importance of proactive risk management measures and potentially an emergency action plan to address any safety concerns.
With a moderate risk rating and a lack of updated emergency preparedness measures, Stedman Marsh Dam presents a unique challenge for water resource and climate enthusiasts. As a vital component of the local water supply infrastructure, it is essential to prioritize its maintenance and security to prevent any potential hazards or disruptions to the surrounding community. The dam's location, design, and condition make it a focal point for ongoing monitoring and maintenance efforts to ensure the safety and sustainability of water resources in the region.

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 Stedman Marsh Dam
Where does the data for Stedman Marsh 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 Low 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.
