About this dam

Chauncey Stillman Dam

The Chauncey Stillman Dam, also known as Camp Pond, is a private structure located in Wassaic, New York. Completed in 1951, this earth dam stands at a height of 18.5 feet and spans a length of 1030 feet, with a storage capacity of 104 acre-feet and a surface area of 9.9 acres. Situated on the TR-Wassaic Creek, this dam serves purposes beyond flood control, including recreation, making it a significant resource for the local community.

Managed by the New York State Department of Environmental Conservation, the Chauncey Stillman Dam is subject to state regulations, inspections, and enforcement measures to ensure its continued safety and functionality. With a hazard potential rated as significant and a fair condition assessment, the dam presents moderate risks that are actively monitored and managed. In the event of an emergency, the dam's Emergency Action Plan is regularly updated to meet guidelines and ensure preparedness for potential inundation events.

For water resource and climate enthusiasts, the Chauncey Stillman Dam offers a fascinating glimpse into the intersection of infrastructure, natural resources, and community engagement. From its design and construction history to its role in water management and recreational activities, this dam showcases the importance of sustainable infrastructure development in supporting both human and environmental well-being. As a private structure with public benefits, the Chauncey Stillman Dam stands as a testament to the ongoing efforts to balance water resource management with the needs of local communities in New York.

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.

FAQ

About Chauncey Stillman Dam

Where does the data for Chauncey Stillman 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.
