Northville Water Supply Dam dam
Northville Water Supply Dam
The Northville Water Supply Dam, also known as the Upper Reservoir Dam, is a privately owned structure located in Northville, New York. Completed in 1940, this earth dam stands at a height of 25 feet and stretches 420 feet in length, with a primary purpose of water supply. It impounds the waters of Hunter Creek, providing a normal storage capacity of 27 acre-feet and a maximum storage capacity of 43 acre-feet.
Managed by the New York State Department of Environmental Conservation (NYS DEC), the Northville Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The spillway, which is uncontrolled and 37 feet wide, has a maximum discharge capacity of 1400 cubic feet per second. Despite its moderate risk level, the dam has not been modified in recent years and is subject to periodic inspections to ensure its ongoing safety and functionality.
For water resource and climate enthusiasts, the Northville Water Supply Dam serves as a critical infrastructure for water management in Hamilton County, New York. Its strategic location and regulated operation by the NYS DEC make it an essential component of the regional water supply system. As climate change impacts continue to affect water availability and quality, the maintenance and monitoring of dams like Northville are crucial for ensuring sustainable water resources for the community and the environment.

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 Northville Water Supply Dam
Where does the data for Northville 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.
