Adamant Pond dam
Adamant Pond
Adamant Pond, also known as Upper Sodom Pond, is a private water resource located in Calais, Vermont. Managed by the Vermont Department of Environmental Conservation (DEC), this recreational dam was completed in 1870 and stands at a height of 10 feet, with a storage capacity of 230 acre-feet. The dam, primarily made of concrete, serves as a popular spot for outdoor enthusiasts looking to enjoy the 50-acre surface area for various recreational activities.
Despite its historical significance and recreational value, Adamant Pond poses a significant hazard potential with a poor condition assessment as of June 2017. The dam's inspection frequency is set at every 3 years, with the last inspection conducted in July 2017. With its location on Beaver Meadow Brook and a drainage area of 2.31 square miles, the dam's structural integrity and maintenance are crucial for ensuring the safety and sustainability of the surrounding environment and community.
As water resource and climate enthusiasts, it is important to recognize the importance of monitoring and managing dams like Adamant Pond to mitigate potential risks and ensure responsible stewardship of our natural resources. With ongoing regulatory oversight and enforcement by the state of Vermont, efforts to improve the condition and safety of the dam will be vital in preserving the ecological balance and recreational opportunities that this cherished water resource provides for generations to come.

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 Adamant Pond
Where does the data for Adamant Pond 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.
