Belvedere Lake Dam dam
Belvedere Lake Dam
Belvedere Lake Dam, located in Roseboom, New York, is a privately owned structure with a primary purpose of recreation. Built in 1900, this earth dam stands at a height of 20 feet and stretches 220 feet in length, providing a storage capacity of 210 acre-feet. The dam sits on TR-Cherry Valley Creek and is regulated by the New York State Department of Environmental Conservation.
Despite its scenic surroundings and recreational value, Belvedere Lake Dam poses a significant hazard potential due to its poor condition assessment. The last inspection in 2018 revealed the dam's deteriorating state, prompting a moderate risk assessment rating. With a spillway width of 32 feet and a maximum discharge of 160 cubic feet per second, the dam's emergency action plan readiness and risk management measures need improvement to ensure public safety.
As water resource and climate enthusiasts monitor the status of Belvedere Lake Dam, concerns linger about its ability to withstand potential hazards and emergencies. With a risk assessment rating of moderate and a significant hazard potential, stakeholders must work towards enhancing the dam's condition assessment, emergency preparedness, and risk management measures to protect the surrounding community and preserve this vital water resource for future generations.

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.
Plan around the weather

About Belvedere Lake Dam
Where does the data for Belvedere 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.
