Lake Rohunta Dam dam
Lake Rohunta Dam
Located in Athol, Massachusetts, Lake Rohunta Dam is a privately owned structure that serves primarily for recreation purposes. Completed in 1943, this concrete dam has a height of 24 feet and a hydraulic height of 21 feet, with a total length of 576 feet. The dam holds a normal storage capacity of 1555 acre-feet and has a maximum storage capacity of 2420 acre-feet, offering ample opportunities for water-based activities in its 315-acre surface area.
Managed by the Department of Conservation and Recreation in Massachusetts, Lake Rohunta Dam is under state regulation, with regular inspections ensuring its satisfactory condition and low hazard potential. The dam controls the flow of Riceville Brook and Ellinwood Brook, providing a controlled environment for recreation enthusiasts to enjoy fishing, boating, and other water-related activities. Despite moderate risk assessment, the dam remains a safe and enjoyable destination for water resource and climate enthusiasts in the Worcester County area.
With its picturesque location and well-maintained structure, Lake Rohunta Dam offers a serene escape for outdoor enthusiasts seeking a recreational haven in the heart of Massachusetts. Whether for fishing, boating, or simply enjoying the natural beauty of the surrounding area, this dam provides a peaceful retreat for water resource and climate enthusiasts looking to connect with nature and enjoy the benefits of a well-managed water resource infrastructure.
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 Lake Rohunta Dam
Where does the data for Lake Rohunta 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.
