Summary
Completed in 1937, this gravity dam stands at a height of 12 feet and has a hydraulic height of 9 feet. With a storage capacity of 4,250 acre-feet, this dam plays a crucial role in managing water resources in the region, particularly for agricultural needs.
The dam, situated on a tributary of the Weweantic River, is regulated by the Department of Conservation and Recreation in Massachusetts. Despite its low hazard potential, the dam's risk assessment is rated as moderate, with a risk level of 3. Although the condition assessment is currently not rated, the dam is subject to regular inspections every 10 years to ensure its structural integrity and safety. Additionally, the dam's emergency action plan and risk management measures are yet to be fully developed and implemented.
Overall, Atwood Upper Reservoir #2 Dam plays a vital role in water resource management in Plymouth County, Massachusetts. With its historical significance and essential function in supporting irrigation activities, the dam serves as a key infrastructure for the local community. As climate change continues to impact water availability and usage, the maintenance and regulation of dams like Atwood Upper Reservoir #2 become increasingly important for sustainable water management in the region.

Dam Data Reference
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.
