About this dam

Crestwood Lake Dam

Crestwood Lake Dam in Crestwood Gardens, New York, is a privately owned concrete structure completed in 1995, standing at 10 feet tall and stretching 64 feet in length. 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

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.
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.
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.

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, environmental 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.

FAQ

About Crestwood Lake Dam

Where does the data for Crestwood Lake Dam come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the Significant hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
