Daniel Green Company Dam dam
Daniel Green Company Dam
The Daniel Green Company Dam, located in Dolgeville, New York, along the East Canada Creek, is a privately owned concrete dam that serves a primary purpose of hydroelectric power generation. Built in 1917, this historic structure stands 20 feet tall and stretches 300 feet in length, with a storage capacity of 114 acre-feet. The dam features an uncontrolled spillway with a width of 200 feet, providing a low hazard potential and a moderate risk assessment rating of 3.
Managed by the New York State Department of Environmental Conservation (NYS DEC), the Daniel Green Company Dam is regulated, permitted, inspected, and enforced by state authorities. While the dam's condition is currently rated as "Not Rated" due to its last inspection in 1984, it is reassuring to note that emergency action plans (EAP) and risk management measures are in place to mitigate any potential risks. With its picturesque location in Herkimer County, this dam serves as a vital resource for renewable energy production and water management in the region.
For water resource and climate enthusiasts, the Daniel Green Company Dam offers a glimpse into New York State's commitment to sustainable energy practices and environmental stewardship. As a key player in the state's hydroelectric infrastructure, this dam represents a blend of history, technology, and conservation efforts aimed at harnessing the power of nature while minimizing risks to surrounding communities. With its moderate risk assessment and low hazard potential, the Daniel Green Company Dam stands as a testament to the careful balance between energy production and environmental protection in the modern era.

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 Daniel Green Company Dam
Where does the data for Daniel Green Company 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.
