Red Hook Mills Dam dam
Red Hook Mills Dam
The Red Hook Mills Dam, located in Annandale-on-Hudson, New York, stands as a stone structure with a height of 26 feet and a length of 80 feet. This privately-owned dam on the Saw Kill river serves primarily for recreational purposes, offering a storage capacity of 104 acre-feet. Despite its historical significance and serene surroundings, the dam poses a significant hazard potential and has not been rated for its current condition.
Managed by the New York State Department of Environmental Conservation, the Red Hook Mills Dam has state-regulated permitting, inspection, and enforcement processes in place. With a spillway width of 40 feet and a maximum discharge capacity of 1000 cubic feet per second, the dam's risk assessment is classified as moderate. However, emergency action plans and inundation maps have not been updated or prepared in recent years, leaving room for improvement in risk management measures.
For water resource and climate enthusiasts, the Red Hook Mills Dam offers a glimpse into the intricate balance between human recreation, environmental protection, and public safety. As stakeholders work towards enhancing the dam's resilience and emergency preparedness, the dam continues to stand as a picturesque reminder of the intersection between man-made infrastructure and natural landscapes in the face of changing climatic conditions.
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 Red Hook Mills Dam
Where does the data for Red Hook Mills 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.
