Amawalk Lake North Dam dam
Amawalk Lake North Dam
Amawalk Lake North Dam, also known as Lake Shenorock Dam, is a privately owned earth dam located in Lincolndale, Westchester County, New York. Built in 1972 for water supply purposes, this dam stands at a height of 11 feet and has a length of 165 feet. It has a storage capacity of 150 acre-feet and covers a surface area of 15 acres, serving the local community with a controlled spillway width of 21 feet.
Despite being categorized as a low hazard potential structure, Amawalk Lake North Dam is deemed to have a very high risk assessment, emphasizing the importance of regular inspections and maintenance. While the last inspection took place in August 2005, the dam's condition is currently listed as "Not Rated." The New York State Department of Environmental Conservation regulates this dam, ensuring compliance with state permitting, inspection, and enforcement requirements to mitigate any potential risks associated with its operation.
Situated on the TR-PLUM BROOK stream, this dam plays a critical role in providing water supply to the area while also being a subject of interest for water resource and climate enthusiasts. With its strategic location and vital function, the Amawalk Lake North Dam stands as a significant infrastructure contributing to the local water management system in New York.

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 Amawalk Lake North Dam
Where does the data for Amawalk Lake North 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.
