Great Lakes High Water

Multiple record high levels were set on the Great Lakes in 2019 and 2020 resulting in increased risks from erosion and coastal flooding. The U.S. Army Corps of Engineers is committed to ensuring public safety while providing technical expertise and assistance during this time of high water around the Great Lakes.
During response operations, our Emergency Management Office conducts emergency operations to save lives and protect improved properties. In the event of natural disasters such as flooding, emergency permit procedures can be activated to expedite permits to reduce further damage, and protect life and property. The Corps of Engineers has authority to provide technical and planning assistance for flood plain management planning. The Great Lakes Hydraulics and Hydrology Office forecasts and monitors water levels of the Great Lakes and the conditions that lead to water level fluctuations.
