Summary
This earth dam stands at a height of 11 feet and spans 100 feet in length, holding a maximum storage capacity of 430 acre-feet. Situated on Mill Creek, the dam serves as a crucial resource for maintaining water levels in the area and supporting recreational activities in the region.
Managed by the local government and regulated by the New York State Department of Environmental Conservation, the Mill Pond Dam has a low hazard potential and a moderate risk assessment rating. While the dam's condition is currently not rated, it undergoes regular inspections and is equipped with an uncontrolled spillway with a width of 3 feet. The surrounding area benefits from the dam's presence, offering a surface area of 90 acres for water-based recreation and supporting a diverse ecosystem.
Enthusiasts of water resources and climate in Suffolk County, New York, can appreciate the significance of the Mill Pond Dam as a vital infrastructure for water management and recreational activities. As efforts continue to ensure the safety and integrity of this historic structure, its role in providing a sustainable water supply and enhancing the local environment remains a key focus for the community and regulatory agencies. With a rich history and ongoing maintenance, the Mill Pond Dam stands as a testament to the intersection of human development and environmental stewardship in the region.

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.
