Summary
Built in 1963, this earth-type dam stands at a height of 9.3 feet and has a storage capacity of 1140 acre-feet, with a normal storage level of 825 acre-feet. The dam covers a surface area of 0.09 square miles and has a drainage area of 0.66 square miles, making it a significant structure for water management in the region.
Managed by the local government and regulated by the Department of Conservation and Recreation, Goose Cove Southwest Dike plays a vital role in water supply management in Essex County, Massachusetts. Despite its fair condition assessment in 2013, the dam has a high hazard potential and risk assessment, indicating the need for regular inspections and maintenance. Additionally, with a high risk management rating of 2, it is crucial for authorities to ensure the safety and functionality of this essential water resource infrastructure for the community.
With its primary purpose being water supply, Goose Cove Southwest Dike serves as a critical asset for ensuring water security in the region. However, its high hazard potential and risk assessment highlight the importance of regular monitoring and maintenance to prevent any potential disasters. As water resource and climate enthusiasts, it is essential to recognize the significance of infrastructure like Goose Cove Southwest Dike in managing water resources sustainably and efficiently for the well-being of the community and the environment.

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.
