Shingle Mill Pond Dam dam
Shingle Mill Pond Dam
Shingle Mill Pond Dam in Salem, Connecticut, is a significant masonry dam completed in 1930 that serves primarily for recreational purposes. The dam stands at a height of 8 feet and has a storage capacity of 55 acre-feet, with a surface area of 9.2 acres and a drainage area of 1.43 square miles. The dam is situated on Shingle Mill Brook and is owned by the state, regulated by the Department of Energy and Environmental Protection (DEEP), and subject to state inspection and enforcement.
The dam has a spillway width of 10 feet and a maximum discharge of 78 cubic feet per second, contributing to its significant hazard potential. Despite its importance in providing recreational opportunities, the dam's condition assessment is currently listed as "Not Rated," highlighting the need for ongoing monitoring and maintenance. While an emergency action plan (EAP) was last revised in 2005, there is room for improvement in ensuring that the dam meets safety guidelines and that appropriate risk management measures are in place.
As a key feature in the New London County landscape, Shingle Mill Pond Dam warrants attention from water resource and climate enthusiasts to ensure its continued safe operation and preservation for future generations. With its rich history dating back to the early 20th century, the dam serves as a reminder of the importance of sustainable water management practices in safeguarding our natural resources and enhancing recreational opportunities in 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 Shingle Mill Pond Dam
Where does the data for Shingle Mill Pond 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 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.
