Summary
Situated along the TR-BRONX RIVER, this dam serves a primary purpose categorized as "Other" and boasts a storage capacity of 72 acre-feet, with a normal storage level of 30 acre-feet. With a spillway width of 40 feet and an uncontrolled spillway type, the dam is designed to manage potential surges in water flow effectively.
Managed by the NYS DEC, this dam is subject to state regulation, inspection, and enforcement to ensure its structural integrity and operational safety. The last inspection in November 2020 rated its condition as satisfactory, with a significant hazard potential but a moderate overall risk assessment. The dam's associated risk management measures and emergency action plan status remain unspecified, emphasizing the importance of ongoing monitoring and preparedness for potential emergencies in the area.
For water resource and climate enthusiasts, Crestwood Lake Dam presents an intriguing case study of a modest yet significant structure within the Westchester, New York region. Its role in water management along the TR-BRONX RIVER, coupled with its private ownership and state regulation, highlights the intricate balance between infrastructure development and environmental stewardship in safeguarding communities against potential hazards and ensuring sustainable water resource management for the future.

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.
