Hailesboro Mill #6 Dam dam
Hailesboro Mill #6 Dam
Hailesboro Mill #6 Dam, located in Hailesboro, New York, stands as a vital structure along the Oswegatchie River for hydroelectric purposes. This concrete dam, standing at a height of 14 feet and with a length of 250 feet, plays a crucial role in generating power while also providing storage capacity of 37 acre-feet. The dam's spillway, with a width of 264 feet, ensures effective water management during high flow events.
Managed by a private entity, this dam is regulated by the New York State Department of Environmental Conservation, reflecting a commitment to safety and environmental compliance. With a significant hazard potential and a moderate risk assessment, ongoing inspections are crucial to ensuring the dam's integrity and functionality. Despite not being rated for condition assessment, the dam's operation is subject to frequent inspections to mitigate any potential risks.
For water resource and climate enthusiasts, Hailesboro Mill #6 Dam represents a fascinating intersection of technology, infrastructure, and natural resources. Its importance in harnessing clean energy from flowing water underscores the critical role of sustainable hydroelectric power in a changing climate landscape. As efforts continue to enhance safety measures and risk management, this dam serves as a reminder of the delicate balance between human development and environmental stewardship in water resource management.

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 Hailesboro Mill #6 Dam
Where does the data for Hailesboro Mill #6 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.
