Reservoir #2 Dam dam
Reservoir #2 Dam
Reservoir #2 Dam, located in Athol, Massachusetts, is a private dam managed by the Department of Conservation and Recreation. The dam serves the primary purpose of flood risk reduction and also provides recreational opportunities for the local community. With a height of 16 feet and a storage capacity of 958 acre-feet, the dam plays a crucial role in managing water resources in the area.
Constructed with rockfill and buttress core types, Reservoir #2 Dam has a significant hazard potential and is classified as having a fair condition assessment. The dam's spillway type is uncontrolled, and it has a surface area of 52.2 acres with a drainage area of 0.53 square miles. The dam's inspection frequency is every 5 years, with the last inspection conducted in May 2014, highlighting the importance of regular maintenance and monitoring to ensure its safety and effectiveness in flood risk reduction.
Despite its moderate risk assessment level, Reservoir #2 Dam remains a vital infrastructure for managing water resources in Worcester County. With its strategic location on a tributary of Mill Brook, the dam's role in flood risk reduction and recreation underscores the importance of maintaining and monitoring its condition to ensure the safety of surrounding communities and the efficient management of water resources in the region.
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 Reservoir #2 Dam
Where does the data for Reservoir #2 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.
