Baltic Mills Dam dam
Baltic Mills Dam
Baltic Mills Dam, located in Enfield, New Hampshire, is a private concrete dam constructed in 1919 on the Mascoma River for hydroelectric purposes. This dam stands at a height of 21 feet and spans 120 feet in length, with a storage capacity of 120 acre-feet. It is regulated by the New Hampshire Department of Environmental Services Dam Bureau and undergoes regular inspections to ensure its safety and compliance with state regulations.
With a low hazard potential and a moderate risk assessment, Baltic Mills Dam is considered to be in fair condition, although its emergency action plan and risk management measures are not currently rated. The dam features an uncontrolled spillway with a width of 96 feet and serves as an important structure for managing water resources in the Grafton County area. Despite its age, Baltic Mills Dam continues to play a vital role in the local hydroelectric industry and provides valuable insights for water resource and climate enthusiasts interested in sustainable energy production and dam safety practices.
As part of the New England District, Baltic Mills Dam contributes to the overall management of water resources in the region and aligns with the state's focus on promoting renewable energy sources. Its location on the Mascoma River offers a unique opportunity for studying the impact of dams on local ecosystems and water quality. By maintaining a proactive approach to dam safety and compliance, Baltic Mills Dam sets a positive example for other private dam owners and underscores the importance of responsible water resource management in the face of changing climate conditions.

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 Baltic Mills Dam
Where does the data for Baltic Mills 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.
