Kasoag Lake Dam dam
Kasoag Lake Dam
Located in Williamstown, New York, the Kasoag Lake Dam stands as a vital structure along the WEST BRANCH FISH CREEK, serving primarily for recreational purposes. Built in 1820, this Earth-type dam boasts a height of 10 feet and a length of 180 feet, with a storage capacity of 192 acre-feet. Despite its historical significance and picturesque setting, the dam's condition assessment reveals a poor state, prompting concerns for its maintenance and long-term viability.
With a hazard potential rated as low and a moderate risk assessment score of 3, the Kasoag Lake Dam poses some level of concern for its structural integrity. The dam's last inspection in May 2017 highlighted its poor condition, raising questions about its ability to withstand potential emergencies. While the dam is regulated and inspected by the NYS DEC, its compliance with state permitting and enforcement measures remains essential to ensure the safety of the surrounding Oswego community and the overall water resources in the area.
As water resource and climate enthusiasts continue to monitor the Kasoag Lake Dam, efforts to address its poor condition and mitigate potential risks are crucial. With a focus on enhancing structural integrity, conducting regular inspections, and implementing necessary maintenance measures, stakeholders can work together to preserve this historic dam and safeguard the local environment. By prioritizing safety and compliance with regulatory standards, the Kasoag Lake Dam can continue to serve as a recreational hub while ensuring the protection of water resources for future generations.

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 Kasoag Lake Dam
Where does the data for Kasoag 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 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.
