Indian Brook Reservoir Dam dam
Indian Brook Reservoir Dam
Indian Brook Reservoir Dam, located in Crotonville, Westchester, New York, stands as a vital water supply infrastructure managed by the local government. Completed in 1889, this Earth-type dam holds a height of 43 feet and a length of 500 feet, with a storage capacity of 369 acre-feet. Serving the primary purpose of water supply, the dam regulates the flow of the Croton River and provides essential resources to the surrounding area.
With a controlled spillway and a maximum discharge capacity of 634 cubic feet per second, Indian Brook Reservoir Dam poses a high hazard potential but maintains a satisfactory condition assessment as of May 2019. Despite its age, the dam undergoes regular inspections every two years to ensure its structural integrity and safety. Additionally, the dam's emergency action plan is up-to-date, although specific details on its guidelines and readiness are not provided in the data.
Climate enthusiasts and water resource professionals alike can appreciate the historical significance and critical role of Indian Brook Reservoir Dam in managing water resources and addressing the region's water supply needs. As a regulated and inspected structure, the dam represents a key component of New York's infrastructure, safeguarding against potential risks and ensuring the continued availability of water for the community.
Dam data reference
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.

About Indian Brook Reservoir Dam
Where does the data for Indian Brook Reservoir 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 High 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.
