Pine Tree Brook Pl-566 Flood Control Dam dam
Pine Tree Brook Pl-566 Flood Control Dam
Located in Milton, Massachusetts, the Pine Tree Brook Pl-566 Flood Control Dam, also known as the Harland Street Dam, stands as a vital structure designed by the USDA NRCS to mitigate flood risk along the Pine Tree Brook. Completed in 1971, this earth dam with a buttress core type has a height of 21 feet and a length of 1275 feet, providing a substantial storage capacity of 1085 acre-feet and serving the primary purpose of flood risk reduction in the area.
Regulated by the Department of Conservation and Recreation in Massachusetts, this significant dam has a satisfactory condition assessment and a moderate risk level. With a drainage area of 4.5 square miles, the dam plays a crucial role in managing water flow and protecting the surrounding community from the potential impacts of flooding. Despite being uncontrolled, the spillway and outlet gates ensure proper water discharge while the dam's inspection frequency of 5 years helps to maintain its structural integrity and overall effectiveness in flood control.
For water resource and climate enthusiasts, the Pine Tree Brook Pl-566 Flood Control Dam serves as an essential infrastructure in the local area, with Ayanna Pressley representing the region in Congress. Its strategic location and design, along with its successful track record in flood risk reduction, highlight the importance of sustainable water management practices in safeguarding communities and ecosystems against the challenges of a changing climate.
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 Pine Tree Brook Pl-566 Flood Control Dam
Where does the data for Pine Tree Brook Pl-566 Flood Control 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.
