Delanson Reservoir Dam dam
Delanson Reservoir Dam
Delanson Reservoir Dam, located in Duanesburg, New York, serves as a crucial water supply source for the community. Constructed in 1915, this earth-type dam stands at a height of 30 feet and spans 500 feet in length. With a maximum storage capacity of 84 acre-feet and a normal storage capacity of 73 acre-feet, the reservoir covers a surface area of 7 acres and is regulated by the New York State Department of Environmental Conservation.
Despite being classified as having a low hazard potential, the dam's risk assessment is moderate. The spillway, which is uncontrolled and 28 feet wide, plays a vital role in managing water flow in case of excess storage. The dam is regularly inspected by the state regulatory agency, with the last inspection conducted in October 2015. This structure is not only essential for water supply purposes but also contributes to the overall sustainability and resilience of the region's water resources.
Delanson Reservoir Dam's historical significance and functional role in water management make it a focal point for water resource and climate enthusiasts. With its strategic location on the TR-Normans Kill river, this dam symbolizes the intersection of human ingenuity and environmental stewardship. As efforts are made to assess and mitigate potential risks associated with the dam, its importance in ensuring water security for the local community remains paramount.

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 Delanson Reservoir Dam
Where does the data for Delanson Reservoir 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.
