Brookside Reservoir Dam Dam
Brookside Reservoir Dam
Brookside Reservoir Dam, located in Amsterdam, New York, is a crucial structure owned and regulated by the local government for water supply purposes. Built in 1882, this Earth-type dam stands at a height of 50 feet and spans 500 feet in length, with a storage capacity of 375 acre-feet. The dam, situated on Bunn Creek, serves as a vital resource for Montgomery County, with a normal storage level of 306 acre-feet and a surface area of 14 acres.
Despite its age, Brookside Reservoir Dam has been deemed to be in satisfactory condition during its latest assessment in March 2018. This high-hazard structure is subject to regular inspections by the New York State Department of Environmental Conservation to ensure its safety and functionality. With a spillway width of 78 feet and uncontrolled spillway type, the dam has a moderate risk level (3) according to the risk assessment conducted. In case of emergency, the dam's emergency action plan (EAP) is up to date, meeting regulatory guidelines for efficient response and management.
For water resource and climate enthusiasts, Brookside Reservoir Dam stands as a historic yet vital infrastructure supporting the water supply needs of Montgomery County. Its presence on Bunn Creek contributes to the region's water management system, offering a significant storage capacity and serving as a critical asset for local communities. As efforts continue to maintain and enhance the dam's safety and resilience, it remains a key component in ensuring water security and sustainability in the area, under the careful oversight of regulatory authorities and emergency preparedness measures.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Brookside Reservoir Dam
Where does the data for Brookside 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 below 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.

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.
