Indian Brook Dam dam
Indian Brook Dam
Indian Brook Dam, located in Plymouth, Massachusetts, serves as a vital irrigation resource in the region. Constructed in 1930, this earth dam stands at a height of 12.5 feet and has a storage capacity of 100 acre-feet, with a normal storage level of 15 acre-feet. The dam regulates the flow of Indian Brook, covering a surface area of 8 acres and draining a watershed area of 6.1 square miles.
Managed by the Massachusetts Department of Conservation and Recreation, Indian Brook Dam is state-regulated and undergoes regular inspections to ensure its structural integrity. Despite being classified as having a high hazard potential, the dam is currently assessed to be in fair condition. In the event of an emergency, protocols are in place, with an Emergency Action Plan last revised in October 2016. Although the dam poses a moderate risk, appropriate risk management measures are in place to mitigate any potential threats.
Water resource and climate enthusiasts will appreciate the importance of Indian Brook Dam in providing irrigation and water regulation services in Plymouth. With its historical significance and ongoing maintenance efforts, the dam stands as a testament to the state's commitment to water resource management and public safety. As a critical infrastructure piece in the region, Indian Brook Dam plays a crucial role in supporting agricultural activities and ensuring water security for the surrounding community.

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 Indian Brook Dam
Where does the data for Indian Brook 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.
