Shaker Pond Dam Dam
Shaker Pond Dam
Shaker Pond Dam, located in Enfield, Connecticut, is a private dam with a primary purpose of recreation. Built in 1880, this earth dam stands at a height of 12 feet and stretches 200 feet in length, creating a surface area of 24.6 acres and a drainage area of 1.3 square miles. The dam has a maximum storage capacity of 80 acre-feet and a maximum discharge rate of 140 cubic feet per second.
Despite being classified as having a "Fair" condition assessment, Shaker Pond Dam poses a significant hazard potential due to its outdated spillway type of "Uncontrolled." The dam is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP), which ensures that it undergoes regular inspections, with the last inspection conducted in August 2019. The dam's emergency action plan (EAP) status, risk assessment, and risk management measures are currently not explicitly specified in the available data.
Given its historical significance and the potential risks associated with its current condition, Shaker Pond Dam serves as a critical site for water resource and climate enthusiasts to monitor and advocate for proper maintenance and safety measures to protect the surrounding community and environment. The dam's location on the Jawbuck Brook, its association with recreation, and its significant hazard potential highlight the importance of ongoing oversight and proactive risk management to ensure the continued safety and sustainability of this iconic structure.

About Shaker Pond Dam
Where does the data for Shaker 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 below 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.
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.
