Summary
The dam, constructed with concrete and buttress core type, stands at a height of 10.6 feet with a hydraulic height of 7.5 feet. It has a storage capacity of 2550 acre-feet, providing water for agricultural needs in the surrounding area. The dam is regulated by the Department of Conservation and Recreation in Massachusetts and undergoes regular state inspections to ensure its safety and functionality.
Despite its significant hazard potential and poor condition assessment, White Island Pond Dam plays a crucial role in water resource management in the region. The dam, built on Red Brook, covers a surface area of 322 acres and has a drainage area of 2.79 square miles. With a moderate risk rating, the dam's risk management measures are yet to be fully assessed, highlighting the importance of ongoing monitoring and maintenance to mitigate potential risks. Although the dam's emergency action plan and inundation maps are not currently prepared, efforts are being made to ensure the safety and security of the surrounding community in case of any unforeseen events.
In the care of the state of Massachusetts, White Island Pond Dam continues to provide essential water resources for irrigation while facing ongoing challenges in terms of its structural integrity and risk assessment. With regular inspections and enforcement measures in place, the dam remains a key infrastructure for water management in Plymouth County. As climate change impacts intensify, the maintenance and monitoring of dams like White Island Pond become increasingly critical to ensure the resilience of water resources in the face of evolving environmental conditions.

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.
