Cox Brook dam
Cox Brook
Cox Brook, located in Moretown, Vermont, is an Earth-type dam with a significant hazard potential. The dam has a storage capacity of 4 acre-feet and covers a surface area of 0.9 acres, with a drainage area of 0.82 square miles. Despite not being regulated by the state, Cox Brook presents a risk that should not be overlooked, as its condition has not been assessed and its emergency action plan is not rated.
Managed by the New England District of the US Army Corps of Engineers, Cox Brook stands as a reminder of the importance of monitoring and maintaining our water resources in the face of changing climate conditions. With a spillway width of 0 feet and no outlet gates, the dam's potential impact on the surrounding area in case of failure cannot be underestimated. Climate enthusiasts and water resource advocates should keep a close eye on Cox Brook and its management to ensure the safety and sustainability of the local environment.
As we continue to face the challenges of climate change and its impact on our water resources, Cox Brook serves as a case study in the importance of proactive risk management and emergency preparedness. With no recent inspection date and no condition assessment, it is crucial for relevant authorities to prioritize the evaluation and maintenance of this dam to prevent any potential disasters. Water resource and climate enthusiasts should advocate for increased oversight and monitoring of structures like Cox Brook to safeguard our communities and natural habitats.
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 Cox Brook
Where does the data for Cox Brook 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.
