Summary
Completed in 1923, this earth dam stands at a height of 36 feet and stretches 560 feet in length, with a storage capacity of 1029 acre-feet. The dam's normal storage capacity is 888 acre-feet, covering a surface area of 198 acres and serving a drainage area of 1.89 square miles along the Silver Stream.
Managed by the New York State Department of Environmental Conservation, the Silver Stream Reservoir Dam is subject to state regulations, inspections, and enforcement measures to ensure its structural integrity and safety. Classified with a high hazard potential due to its location and purpose, the dam has been assessed as satisfactory with a moderate risk level. Despite its age, the dam has been well-maintained and meets guidelines for emergency action plans, highlighting its importance in water resource management in the region.
With Representative Sean Patrick Maloney overseeing the district, the Silver Stream Reservoir Dam plays a crucial role in providing a reliable water supply for the community of C. Newburgh. As climate change impacts water resources, the dam's significance in ensuring water security and resilience in the face of evolving environmental challenges becomes increasingly apparent. As a notable feature in the region's water infrastructure, the Silver Stream Reservoir Dam stands as a testament to effective water resource management and the importance of maintaining critical infrastructure for future generations.

Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
