Welcome to Great Lakes Water Quality

The Great Lakes project invites participants to explore maps and graphs and contribute water quality data from across the Great Lakes watershed region, including parts of the United States and Canada. This web-based mapping and graphing collaboration tool is designed to engage students, volunteers, and community members in Great Lakes water science.

In Great Lakes FieldScope, you’ll find maps to explore, such as:

  • Areas of Concern (pollution)
  • Fish Spawning Locations
  • Lakes, Streams, and Wetlands
  • Watershed Boundaries
  • And more!
