Summary
With a height of 30 feet and a storage capacity of 131,000 acre-feet, the dam plays a crucial role in managing water levels and mitigating potential flooding events. Despite its high hazard potential, the dam is regularly inspected and maintained by the US Army Corps of Engineers to ensure its structural integrity and readiness for emergency situations.
In addition to flood risk reduction, the dam also serves recreational purposes and covers a drainage area of 64 square miles. With a spillway width of 175 feet and a maximum discharge of 28,500 cubic feet per second, the dam is equipped to handle various water management scenarios efficiently. USACE actively engages with local emergency managers and the public to raise awareness about the dam and collaborates on emergency preparedness measures to address potential risks associated with severe weather events and dam operations.
As part of its risk management strategy, USACE continuously monitors the dam's condition, prioritizes risk-reducing activities, and updates the emergency action plan regularly. By working closely with local stakeholders and implementing maintenance and repair measures as needed, USACE ensures that Everett Dam - Dike 2 remains a reliable and resilient infrastructure to protect the surrounding communities from flood hazards.

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.
