Quinebaug River Pond Dam dam
Quinebaug River Pond Dam
Quinebaug River Pond Dam, also known as West Dudley Dam, is a concrete gravity dam located in Thompson, CT along the Quinebaug River in Worcester County, Massachusetts. Built in 1919, this private dam serves a primary purpose of hydroelectric power generation and stands at a height of 13 feet with a length of 259 feet. It has a storage capacity of 201 acre-feet and covers a surface area of 31 acres, while controlling a maximum discharge of 8990 cubic feet per second.
Managed by the Federal Energy Regulatory Commission, Quinebaug River Pond Dam is classified as having a low hazard potential and a very high risk assessment rating. Despite not being regulated or inspected by the state, the dam features a controlled spillway with a width of 199 feet and 8 other controlled outlet gates. The last inspection date was in May 2017 with a scheduled inspection frequency of 3 years. While the condition assessment is not available, measures for risk management and emergency action planning are not detailed.
Overall, Quinebaug River Pond Dam remains an important infrastructure for hydroelectric power generation in the region, highlighting the intersection between water resource management and climate considerations. With its historical significance and critical role in energy production, continued monitoring and evaluation of its structural integrity and risk management measures are essential for ensuring the safety and sustainability of this vital water resource feature.
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.

About Quinebaug River Pond Dam
Where does the data for Quinebaug River 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 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.
