Dark Brook Reservoir Dike A dam
Dark Brook Reservoir Dike A
Dark Brook Reservoir Dike A, located in Auburn, Massachusetts, is a significant earth dam built in 1950 for the primary purpose of recreation. The dam stands at a height of 11 feet with a hydraulic height of 5 feet and a length of 375 feet, creating a reservoir with a normal storage capacity of 2597 acre-feet and a surface area of 288 acres. The reservoir serves as a popular recreational spot in Worcester County, offering opportunities for boating, fishing, and other water-based activities.
Managed by the Department of Conservation and Recreation, Dark Brook Reservoir Dike A has a state-regulated status with regular inspections to ensure its satisfactory condition. Despite its significant hazard potential, the dam is maintained to meet high-risk management standards, with a comprehensive risk assessment indicating a risk level of 2 (High). The surrounding area is closely monitored for any potential emergencies, with emergency action plans in place to address any unforeseen situations effectively.
Water resource and climate enthusiasts will appreciate the detailed information available on Dark Brook Reservoir Dike A, including its construction specifications, storage capacity, and risk management measures. This earth dam not only provides recreational opportunities for visitors but also serves as a vital infrastructure for water resource management in the region. Its maintenance and regulatory oversight by state agencies ensure the safety and sustainability of the reservoir for both recreational and environmental purposes in Worcester 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 Dark Brook Reservoir Dike A
Where does the data for Dark Brook Reservoir Dike A 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.
