For educators
Every lake on this site is a free, real-data teaching object: an interactive 3D basin built from actual Michigan DNR depth surveys, with live weather, fish data, and an on-map measuring tool. If you teach in Michigan, your nearest lake is probably here.
What a classroom can do with it
- Earth science — read real contour lines in 3D, compare glacial kettle lakes to river impoundments, and see how depth shapes a lake.
- Life science — explore fish communities from DNR surveys, stocking history, and angler records; discuss why species live where they do.
- Geography & data literacy — measure distances and depths on the map, compare lakes across counties, and trace data to its public sources (every page cites them).
Built school-friendly
No accounts, no sign-ins, and no ad networks or cross-site advertising trackers — the pages are plain, fast, and work on Chromebooks. Basic site analytics help us understand aggregate use. Everything derives from public government data, cited on every page.
Tell us how you’d use it
We’re exploring lesson-ready material for Michigan classrooms. If that interests you, we’d genuinely like to hear what would help — grade level, subject, and what you’d want from a lake page.
For teachers and administrators — students shouldn’t send personal information. Depth data is historical survey reference, not for navigation.
