Breeds Pond Lantern Rock Dike #4 dam
Breeds Pond Lantern Rock Dike #4
Breeds Pond Lantern Rock Dike #4 is a key water resource infrastructure in Lynn, Essex County, Massachusetts, completed in 1914 for water supply purposes. This Earth-type dam, standing at 30 feet high with a hydraulic height of 25 feet, plays a vital role in storing and managing water from Moore's Brook tributary of the Saugus River. With a storage capacity of 4400 acre-feet, the dam covers a surface area of 192 acres and serves a drainage area of 0.95 square miles.
Despite its age, Breeds Pond Lantern Rock Dike #4 is regularly inspected by the Department of Conservation and Recreation to ensure its safety and functionality. The dam, with a fair condition assessment and a high hazard potential due to its age, poses a high risk (rated 2 out of 5) and is closely monitored for any necessary risk management measures. The dam has no spillway and no locks but stands as a critical structure for maintaining water supply in the region.
Owned and regulated by the local government, this dam has a strong enforcement and inspection process in place to mitigate any potential risks. The surrounding area is at high risk of inundation in case of a breach, emphasizing the importance of continued monitoring and maintenance of Breeds Pond Lantern Rock Dike #4 for the safety and security of the community and the water resources it supports.
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 Breeds Pond Lantern Rock Dike #4
Where does the data for Breeds Pond Lantern Rock Dike #4 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.
