Windsor Minerals Pond #9 dam
Windsor Minerals Pond #9
Windsor Minerals Pond #9, also known as Cwm Tailings Pond #9, is a private-owned earth dam located in West Windsor, Vermont. Built in 1972 by SOILS ENGINEERING, this tailings pond stands at a height of 40 feet and spans a length of 1620 feet, with a storage capacity of 48 acre-feet. The primary purpose of this structure is for tailings storage, serving as a containment area for waste materials from mining operations.
The dam is regulated and inspected by the Vermont Department of Environmental Conservation (DEC) to ensure its safety and compliance with state regulations. With a low hazard potential and a satisfactory condition assessment, Windsor Minerals Pond #9 poses minimal risk to surrounding areas. The last inspection took place in 2009, with a scheduled inspection frequency of every 10 years. The dam's emergency action plan status and risk assessment information are currently unavailable.
As a vital component of the Mill Brook-TR watershed, the management and upkeep of Windsor Minerals Pond #9 are crucial for maintaining water resources and mitigating potential environmental impacts. Climate and water resource enthusiasts would be interested in the structural details and regulatory oversight of this earth dam, which plays a significant role in preserving the ecological balance of the region.

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 Windsor Minerals Pond #9
Where does the data for Windsor Minerals Pond #9 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.
