Bolivar Pond Dam dam
Bolivar Pond Dam
Bolivar Pond Dam, located in Canton, Massachusetts, is a significant structure regulated by the Department of Conservation and Recreation. Completed in 2006, this earth dam stands at a height of 12 meters with a hydraulic height of 12.7 meters. It serves a primary purpose of "Other" and boasts a storage capacity of 191 acre-feet, with a normal storage level of 120 acre-feet. The dam is associated with Steep Hill Brook, Beaver Meadow Brook, and Massapoag Brook, highlighting its importance in managing water resources in the region.
With a significant hazard potential and a satisfactory condition assessment as of 2015, Bolivar Pond Dam plays a crucial role in mitigating flood risks and ensuring water supply reliability in the area. Its spillway type is uncontrolled, signaling the importance of regular inspections and maintenance to uphold its structural integrity. The dam's risk assessment is classified as moderate, indicating the necessity for ongoing risk management measures to safeguard the surrounding communities and environment.
Representing a collaboration between local government entities and state regulatory agencies, Bolivar Pond Dam stands as a testament to the vital role of infrastructure in water resource management and climate resilience efforts. As a key component of the region's water infrastructure, this dam underscores the importance of proactive risk assessment, emergency preparedness, and ongoing maintenance to ensure the safety and sustainability of water resources in Norfolk County, Massachusetts.

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 Bolivar Pond Dam
Where does the data for Bolivar 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 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.
