Holbrook Mill Pond Dam dam
Holbrook Mill Pond Dam
The Holbrook Mill Pond Dam, located in Millbury, Massachusetts, is a private structure regulated by the Department of Conservation and Recreation. This concrete dam stands at a height of 18 feet with a hydraulic height of 12 feet, serving a primary purpose that falls under "Other." With a storage capacity of 6.46 acre-feet and a surface area of 0.9 acres, this dam plays a significant role in managing water resources in the area.
Despite its importance, the Holbrook Mill Pond Dam is classified as having a poor condition assessment and a significant hazard potential. The last inspection conducted in August 2015 highlighted the need for improvements to meet safety standards. With a high risk assessment rating of 2, it is crucial for stakeholders to prioritize risk management measures and ensure the dam's structural integrity is maintained to prevent potential disasters and protect the surrounding environment.
Enthusiasts interested in water resource management and climate change should pay attention to the Holbrook Mill Pond Dam as it serves as a critical infrastructure in Worcester County, Massachusetts. With the dam's condition assessment flagged as poor and a high risk assessment rating, stakeholders must work towards implementing necessary upgrades and maintenance to ensure the safety and sustainability of this essential water resource structure.

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 Holbrook Mill Pond Dam
Where does the data for Holbrook Mill 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.
