Summary

With a dam height of 113 feet and a length of 1070 feet, the dam has a storage capacity of 49,760 acre-feet and a normal storage level of 43,500 acre-feet. Situated on the West Branch Croton River, the dam plays a crucial role in managing water resources in the region, with a maximum discharge capacity of 16,500 cubic feet per second.

The dam is regulated by the New York State Department of Environmental Conservation and undergoes regular inspections and enforcement measures to ensure its structural integrity and safety. With a high hazard potential and a satisfactory condition assessment, the dam is considered to have a very high risk rating, emphasizing the importance of effective risk management measures. Despite its age, the dam continues to serve as a vital infrastructure for water management in the area, reflecting the enduring importance of water resources in the face of changing climate conditions.

As a key component of the local government's water supply infrastructure, Croton Falls Dam stands as a testament to the ongoing efforts to safeguard and manage water resources in Putnam County, New York. With its controlled spillway and high-risk potential, the dam highlights the critical role of infrastructure in adapting to climate challenges and ensuring water security for communities. Through consistent monitoring and maintenance, the dam remains a reliable resource for water supply while also serving as a reminder of the interconnectedness between water resources, climate resilience, and infrastructure management 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. 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

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, 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.
