Arlington Mill Res Evergreen Dike dam
Arlington Mill Res Evergreen Dike
The Arlington Mill Reservoir Evergreen Dike, also known as the East Dike, is a key water resource infrastructure located in Salem, New Hampshire. Built in 1922, this earth dam stands at a height of 31 feet and spans 500 feet in length, serving primarily as a water supply facility. With a storage capacity of 5,680 acre-feet and a drainage area of 20.81 square miles, this structure plays a crucial role in managing water resources in the region.
Managed by the NHDES Dam Bureau and regulated by the state of New Hampshire, the Arlington Mill Reservoir Evergreen Dike is inspected regularly to ensure its structural integrity. Despite being classified as having a significant hazard potential, the dam is assessed to be in fair condition. In case of emergencies, the risk assessment for this dam is moderate, highlighting the importance of preparedness and risk management measures. As a significant piece of infrastructure in the area, the Arlington Mill Reservoir Evergreen Dike serves as a critical component in water resource management and climate resilience efforts.
Climate enthusiasts and water resource experts can appreciate the historical significance and functional importance of the Arlington Mill Reservoir Evergreen Dike in maintaining a reliable water supply for the region. With its controlled spillway and adequate storage capacity, this earth dam plays a vital role in managing water flow and mitigating flood risks along the Spickett River. As efforts continue to monitor and assess the condition of this dam, it remains a key asset in ensuring water security and resilience in Salem, New Hampshire, and beyond.

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 Arlington Mill Res Evergreen Dike
Where does the data for Arlington Mill Res Evergreen Dike 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.
