Lake Level Viewer: United States Great Lakes

Created: 11/18/2014 - Updated: 2/27/2020


This tool helps users visualize lake level changes that range from six feet above to six feet below historical long-term average water levels in the Great Lakes, along with potential shoreline and coastal impacts. Communities can use this information to determine what preparations make the most sense in planning for water level change scenarios. Preparations might include zoning restrictions, infrastructure improvements, and habitat conservation. Information obtained from this tool also provides a good lead-in for community discussions about climate change.


  • Helps users visualize impacts of increased and decreased water levels
  • Displays information about the certainty of water extent
  • Allows investigation of water depth
  • Correlates socioeconomic data with lake level change
  • Provides direct access to data and services for customized analysis
