Marlborough Water District Dam & Dike dam
Marlborough Water District Dam & Dike
The Marlborough Water District Dam & Dike, located in Marlboro, Ulster County, New York, is a crucial structure for water supply in the area. Completed in 1964, this earth dam stands at 23 feet high and spans 280 feet in length, with a storage capacity of 53 acre-feet. Situated along the TR-Hudson River, the dam plays a vital role in managing water resources for the region, with a significant hazard potential due to its location and design.
Managed by the local government, the Marlborough Water District Dam & Dike is regulated by the New York State Department of Environmental Conservation (NYS DEC), ensuring proper permitting, inspection, and enforcement measures are in place. The dam features an uncontrolled spillway with a width of 20 feet and has a maximum discharge capacity of 360 cubic feet per second, serving as a critical infrastructure for water management in the area. Despite its age, the dam's condition assessment is not rated, indicating the need for regular inspections and maintenance to ensure its continued efficacy and safety.
With a moderate risk assessment score of 3, the Marlborough Water District Dam & Dike demonstrates the importance of ongoing risk management measures and emergency preparedness. As a key component of the local water supply system, this structure requires vigilant monitoring and maintenance to safeguard water resources and protect the surrounding community from potential hazards. As climate change continues to impact water resources, structures like the Marlborough Dam play a pivotal role in ensuring the resilience and sustainability of water management practices in the region.

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 Marlborough Water District Dam & Dike
Where does the data for Marlborough Water District Dam & Dike 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.
