NOAA Office for Coastal Management
This web-based tool creates visuals that capture lake level changes that range from six feet above to six feet below historical long-term average water levels in the Great Lakes. Potential shoreline and coastal impacts are also provided. This information can be used to determine appropriate preparations, including zoning restrictions, infrastructure improvements, and habitat conservation.
