Goodnow Flowage Dam dam
Goodnow Flowage Dam
Goodnow Flowage Dam, located in North River, Essex County, New York, is a privately owned dam on the Goodnow River. The dam serves primarily for recreational purposes, offering a serene 339-acre surface area for activities such as boating and fishing. With a height of 25 feet and a length of 350 feet, the earth dam holds a storage capacity of 2,827 acre-feet and has a controlled spillway width of 28 feet.
Managed by the New York State Department of Environmental Conservation (NYS DEC), the dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and compliance. Despite being rated as having low hazard potential and not yet assessed for condition, the dam poses a very high risk due to its failure consequences. While the Emergency Action Plan (EAP) status and risk management measures are currently undetermined, the dam's risk level underscores the importance of ongoing monitoring and maintenance to safeguard the surrounding community and environment from potential threats.
The Goodnow Flowage Dam, situated within the Buffalo District of the US Army Corps of Engineers, stands as a vital structure for recreational enjoyment in the region. As climate change continues to impact water resources and infrastructure, ensuring the resilience and safety of dams like Goodnow Flowage becomes increasingly crucial. By staying informed and proactive in risk assessment and management, water resource and climate enthusiasts can contribute to the sustainable management of these vital assets 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 Goodnow Flowage Dam
Where does the data for Goodnow Flowage 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.
