Carpenter Pond Dam dam
Carpenter Pond Dam
Carpenter Pond Dam, located in Quaker Ridge, New York, is a masonry-type dam built in 1925 with a height of 16 feet and a length of 156 feet. It serves multiple purposes, including flood control and water storage, with a maximum capacity of 16 acre-feet and a normal storage level of 5 acre-feet. The dam is situated on the Sheldrake River and is regulated by the New York State Department of Environmental Conservation (NYS DEC).
Despite its age and historical significance, Carpenter Pond Dam is currently rated as having a poor condition assessment, with a significant hazard potential. The last inspection in November 2020 revealed the need for improvements, and the dam is scheduled for regular inspections every four years. The risk assessment for the dam is moderate, with measures in place to manage potential risks and ensure public safety.
Water resource and climate enthusiasts will find Carpenter Pond Dam a fascinating example of early dam construction in New York State. Its location on the Sheldrake River and its role in flood control make it a crucial piece of infrastructure in the region. However, the dam's poor condition and significant hazard potential highlight the importance of ongoing monitoring and maintenance to ensure its continued functionality and safety 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 Carpenter Pond Dam
Where does the data for Carpenter 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 Significant 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.
