Hayes Pond Dam dam
Hayes Pond Dam
Hayes Pond Dam, located in Otis, Massachusetts, is a private concrete structure that was completed in 1840 for recreational purposes. The dam stands at a height of 12 feet with a hydraulic height of 9.5 feet, and it holds a storage capacity of 345 acre-feet. It is state-regulated by the Department of Conservation and Recreation, with inspections conducted every 10 years. The dam is classified as low hazard potential and is currently assessed to be in fair condition as of the last inspection in 2009.
The dam is situated on a tributary of Hop Brook and serves as a popular recreational spot in Berkshire County. With a surface area of 0.03 square miles and a drainage area of 0.85 square miles, the dam offers opportunities for fishing, boating, and other outdoor activities. Despite its age, Hayes Pond Dam continues to provide valuable recreational resources to the community while maintaining a moderate risk level.
Although the dam's emergency action plan status and risk management measures are not specified, its overall condition is considered fair, and it meets state permitting and inspection requirements. With its historical significance and ongoing recreational value, Hayes Pond Dam serves as a vital water resource in the region and highlights the importance of balancing environmental conservation with public enjoyment.

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 Hayes Pond Dam
Where does the data for Hayes 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 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.
