Eddyville Dam dam
Eddyville Dam
Eddyville Dam, located on the Rondout Creek in New Salem, Ulster County, New York, is a historic masonry dam completed in 1850 with a height of 12 feet and a length of 220 feet. With a storage capacity of 90 acre-feet and a surface area of 15 acres, the dam serves a primary purpose of "Other" and is designated as a low hazard potential structure with a moderate risk assessment rating. Despite not being rated for its condition, the dam is state-regulated and subject to regular inspection, permitting, and enforcement by the New York State Department of Environmental Conservation.
Owned privately, Eddyville Dam is situated in a picturesque location and plays a crucial role in regulating the flow of the Rondout Creek. The dam features an uncontrolled spillway with a width of 220 feet and is not associated with any other structures in the area. While the dam has not been modified in recent years and lacks specific information on emergency action plans or risk management measures, its overall risk level is considered moderate. The dam is not under the jurisdiction of the US Army Corps of Engineers, highlighting the responsibility of the private owner in managing and maintaining this essential water resource infrastructure.
For water resource and climate enthusiasts, Eddyville Dam offers a fascinating glimpse into the historical development of water management infrastructure in New York. As a prominent masonry dam with a rich heritage dating back to the mid-19th century, the dam continues to provide valuable water storage and flow regulation services in the region. With its low hazard potential and moderate risk assessment, the dam represents a unique blend of historical significance and functional utility, underscoring the importance of balancing heritage preservation with modern-day water resource management practices.
Dam data reference
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 Eddyville Dam
Where does the data for Eddyville 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.
