Nunda Water Supply Dam dam
Nunda Water Supply Dam
Nunda Water Supply Dam, located in Nunda, Livingston County, New York, serves as a vital source of water supply for the local community. Completed in 1962, this Earth-type dam stands at a height of 26 feet and has a length of 125 feet. With a storage capacity of 96 acre-feet and a maximum discharge of 670 cubic feet per second, the dam plays a crucial role in regulating water flow in TR-Newville Creek.
Managed by the local government and regulated by the New York State Department of Environmental Conservation, Nunda Water Supply Dam has a low hazard potential and is classified as not rated in terms of condition assessment. Despite being last inspected in July 1999, the dam is considered to have a very high risk due to its age and the potential impact of failure. The controlled spillway with a width of 20 feet ensures efficient water release during periods of high flow, enhancing the safety and stability of the dam.
Water resource and climate enthusiasts can appreciate the significance of Nunda Water Supply Dam in maintaining a reliable water supply for the community while managing potential risks associated with its operation. With its strategic location in the Baltimore District and its essential role in water regulation, the dam serves as a vital infrastructure for water management in the region. As efforts are made to enhance the dam's risk management measures and ensure its long-term stability, Nunda Water Supply Dam remains a critical asset for sustainable water resource management in Livingston County, 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 Nunda Water Supply Dam
Where does the data for Nunda Water Supply 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.
