Brooks Hollow Dam dam
Brooks Hollow Dam
Brooks Hollow Dam, located in Orange County, New York, is a Federal-owned masonry dam on the Brooks Hollow stream. With a height of 10 feet and a storage capacity of 62.3 acre-feet, this dam serves a primary purpose classified as "Other" and has a spillway width of 30 feet. Despite being rated as having a low hazard potential, the dam is considered to have a moderate risk level, indicating the need for ongoing monitoring and risk management measures.
Managed by the US Army Corps of Engineers' Philadelphia District, Brooks Hollow Dam is regulated by the New York State Department of Environmental Conservation and undergoes regular inspection, permitting, and enforcement to ensure its safety and compliance with state regulations. While the dam's condition is currently rated as "Not Rated," its risk assessment suggests a moderate level of risk, prompting the need for a comprehensive emergency action plan and continued risk assessment to mitigate potential hazards and ensure the safety of surrounding communities and ecosystems.
For water resource and climate enthusiasts, Brooks Hollow Dam presents an intriguing case study of a small but significant structure that plays a vital role in water management and environmental protection. With its unique design and purpose, this dam serves as a reminder of the interconnectedness of water infrastructure, regulatory oversight, and risk management in safeguarding our natural resources and communities from potential hazards and emergencies.
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 Brooks Hollow Dam
Where does the data for Brooks Hollow 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 Low 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.
