Lower Ausable Lake Dam dam
Lower Ausable Lake Dam
Lower Ausable Lake Dam, situated in Saint Huberts, Essex County, New York, is a masonry dam completed in 1912 with a primary purpose of recreation. The dam stands at a height of 10 feet and has a length of 91 feet, creating a reservoir with a normal storage capacity of 563 acre-feet. It is regulated by the New York State Department of Environmental Conservation and undergoes regular inspections to ensure its structural integrity.
The dam's spillway type is controlled, with a width of 40 feet, and it has a significant hazard potential according to the data. Despite this, the condition assessment in 2019 deemed it satisfactory, with a very high risk assessment rating. The dam is associated with the East Branch Ausable River and offers opportunities for outdoor enthusiasts to enjoy the surrounding natural beauty. With its historical significance and importance for recreation, Lower Ausable Lake Dam is a vital part of the water resource infrastructure in the area.
Overall, Lower Ausable Lake Dam serves as a crucial structure for water management and recreational purposes in the region. Its presence along the East Branch Ausable River contributes to the local ecosystem and provides a scenic backdrop for outdoor activities. With ongoing inspections and risk assessments, efforts are being made to ensure the safety and functionality of the dam for both residents and visitors alike, highlighting the intersection of water resource management and climate resilience at this unique location.

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 Ausable Lake Dam
Where does the data for Lower Ausable Lake 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.
