Diversion Dam dam
Diversion Dam
The Diversion Dam in Worcester, Massachusetts, is a private structure that serves as a recreational spot along the Quinebaug River. Owned privately and regulated by the Department of Conservation and Recreation, this masonry dam stands at 16 feet high with a hydraulic height of 10 feet. With a primary purpose of recreation, the dam offers a storage capacity of 91 acre-feet and covers a surface area of 6 acres.
Although the dam's hazard potential is considered significant, its condition assessment is rated as fair. Last inspected in December 2014, the structure is monitored every 5 years for safety. With a moderate risk assessment rating, the Diversion Dam plays a vital role in water management and recreational activities in the area. As a buttress dam with uncontrolled spillway, it provides both functional and aesthetic value to the community of Southbridge.
Enthusiasts of water resources and climate will find the Diversion Dam to be a fascinating structure along the Quinebaug River in Worcester, Massachusetts. With its historical significance and recreational opportunities, this masonry dam is a key feature in the region's water management infrastructure. Despite its moderate risk assessment, the dam continues to be a popular destination for outdoor activities and serves as a reminder of the importance of sustainable water resource management in the face of climate change.
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 Diversion Dam
Where does the data for Diversion 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.
