Lower Earlville Reservoir Dam dam
Lower Earlville Reservoir Dam
Lower Earlville Reservoir Dam, located in Earlville, New York, is a privately owned structure regulated by the New York State Department of Environmental Conservation. The dam stands at a height of 25 feet and spans a length of 300 feet, with a normal storage capacity of 20 acre-feet and a maximum storage of 35 acre-feet. The primary purpose of the dam is for recreation, serving as a scenic reservoir on the TR-SANGERFIELD RIVER with a surface area of 3 acres for outdoor enthusiasts to enjoy.
Although the dam has a significant hazard potential, it is currently in a condition that has not been rated. Regular inspections, with a frequency of 4 times a year, are conducted to ensure the safety and reliability of the structure. In case of emergencies, an Emergency Action Plan (EAP) is in place, last revised in October 2019. Despite the moderate risk assessment, the dam continues to provide recreational opportunities while being mindful of potential risks and management measures to mitigate any dangers.
Overall, Lower Earlville Reservoir Dam presents a picturesque setting for water resource and climate enthusiasts to appreciate the beauty of nature while being aware of the importance of dam safety and risk management. With its controlled spillway and regulated state jurisdiction, the dam serves as a vital recreational resource within the community, offering both leisure and potential challenges that highlight the importance of responsible stewardship and maintenance of water infrastructure in the face of changing environmental conditions.

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 Lower Earlville Reservoir Dam
Where does the data for Lower Earlville Reservoir 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.
