Summary
Built in 1909, this concrete dam stands at a height of 12 feet and stretches 100 feet in length. With a storage capacity of 290 acre-feet and a surface area of 34 acres, the dam helps in regulating the flow of the Indian River and supports a drainage area of 158 square miles.
Managed by the local government and regulated by the New York State Department of Environmental Conservation, the Antwerp Village Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its age, the dam has undergone minimal modifications over the years and continues to serve its primary purpose effectively. With a moderate risk assessment rating of 3, the dam's risk management measures are yet to be specified, highlighting the need for ongoing monitoring and maintenance to ensure its longevity and safety for the surrounding community.
For water resource and climate enthusiasts, the Antwerp Village Dam represents a historical infrastructure that has stood the test of time in providing essential water supply services. With its uncontrolled spillway and moderate risk assessment, the dam serves as a reminder of the importance of maintaining and managing aging infrastructure to mitigate potential risks and ensure the sustainable use of water resources in the region. As efforts to assess and address the dam's condition continue, collaboration between local authorities and regulatory agencies remains crucial in safeguarding the dam's integrity and the community's water supply needs for years to come.

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.
