Summary
This earth-type dam, primarily designed for recreational purposes, stands at a height of 8.95 feet and has a storage capacity of 42 acre-feet. With a hazard potential rated as significant and a fair condition assessment, the dam is inspected every five years to ensure its safety and functionality.
The dam, built on South Brook, has a drainage area of 2.15 square miles and a surface area of 6.4 acres. It features an uncontrolled spillway type and a maximum storage capacity of 42 acre-feet. Despite its moderate risk assessment rating, the dam serves as a key recreational spot in the region, offering opportunities for outdoor activities and water-based leisure. The surrounding area provides a picturesque setting for nature enthusiasts and climate advocates to appreciate the importance of water resource management.
Given its location in Plymouth County, Massachusetts, South Brook Dam plays a crucial role in water resource conservation and flood control measures in the region. As a part of the local government's infrastructure, the dam serves as a reminder of the delicate balance between human development and environmental preservation. Climate enthusiasts can appreciate the dam's role in providing recreational opportunities while also recognizing the need for responsible stewardship of water resources in a changing climate.

Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
