Lake Nancy Dam dam
Lake Nancy Dam
Lake Nancy Dam, located in Hagedorns Mills, Saratoga County, New York, is a local government-owned structure that serves primarily for recreational purposes. Built in 1977, this earth dam stands at a height of 17 feet and spans a length of 190 feet, with a storage capacity of 1,093 acre-feet. The dam overlooks Ladman Creek and boasts a surface area of 62 acres, offering a picturesque setting for water resource and climate enthusiasts to enjoy.
Managed by the New York State Department of Environmental Conservation (NYS DEC), Lake Nancy Dam is regulated and inspected regularly to ensure its safety and functionality. With a low hazard potential and a moderate risk assessment rating, the dam is deemed to be in good condition, although it has not been officially rated. Its spillway, classified as uncontrolled, has a width of 40 feet, allowing for controlled water discharge during high-flow events. The dam's emergency action plan status and risk management measures have not been updated recently, indicating potential areas for improvement in emergency preparedness.
Overall, Lake Nancy Dam presents an inviting opportunity for outdoor recreation and appreciation of natural resources in the heart of New York State. With its tranquil setting, moderate risk assessment, and ongoing regulatory oversight, this structure serves as a valuable asset for the local community and water enthusiasts alike.

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 Nancy Dam
Where does the data for Lake Nancy 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.
