Moore dam
Moore
Moore, also known as the Samuel C. Moore Station Dam, is a privately owned structure located in Barnet, VT, along the Connecticut River in New Hampshire. Built in 1957, this concrete dam serves primarily for hydroelectric purposes, with additional functions for recreation. Standing at a height of 149 feet and a length of 2920 feet, Moore has a storage capacity of 223,722 acre-feet and a maximum discharge rate of 211,300 cubic feet per second.
Managed by the NHDES Dam Bureau and regulated by the Federal Energy Regulatory Commission, Moore poses a high hazard potential due to its size and location. Despite undergoing regular inspections, its condition assessment is currently not available, and there are no specific risk management measures in place. With a very high risk rating of 1, Moore's emergency action plan was last revised in December 2018, emphasizing the need for preparedness and adherence to safety guidelines in case of any unforeseen events.
For water resource and climate enthusiasts, Moore presents an intriguing case study in dam infrastructure and risk management. As a significant hydroelectric facility with a substantial storage capacity, its impact on the local ecosystem and surrounding communities is substantial. The high hazard potential and very high risk rating underscore the importance of ongoing monitoring and maintenance to ensure the safety and integrity of Moore and its operations for the future.
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.
Plan around the weather

About Moore
Where does the data for Moore 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 High 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.
