Lake Peekskill Dam dam
Lake Peekskill Dam
Lake Peekskill Dam, located in Putnam, New York, was completed in 1928 and serves as a vital structure for recreation purposes, offering a serene environment for water resource and climate enthusiasts to enjoy. This concrete dam stands at a height of 16 feet and has a length of 120 feet, creating a storage capacity of 1357 acre-feet. The dam overlooks the picturesque Hollowbrook River and covers a surface area of 52 acres, providing a tranquil setting for outdoor activities.
Managed by the local government, Lake Peekskill Dam is regulated by the New York State Department of Environmental Conservation, ensuring compliance with state inspection and enforcement protocols. With a high hazard potential and a moderate risk assessment rating, the dam remains a critical infrastructure that requires regular monitoring and maintenance to uphold its structural integrity. Despite not having a current condition assessment, the dam's Emergency Action Plan was last revised in June 2019, indicating preparedness for potential emergencies.
As part of the Philadelphia District under the US Army Corps of Engineers, Lake Peekskill Dam's uncontrolled spillway and proximity to Sean Patrick Maloney's Congressional district underscore the importance of ongoing risk management measures. With its rich history and significant impact on the local community, this dam continues to be a focal point for water conservation efforts and climate resilience strategies in the region.
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 Lake Peekskill Dam
Where does the data for Lake Peekskill 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.
