About GLOS
We put lake information into peoples’ hands in support of the Smart Great Lakes vision.

A bi-national nonprofit, GLOS provides end-to-end data services that support science, policy, management, and industry in the U.S. and Canada.
Whether deciding to venture out on a boat or tracking the lakes’ changes from season to season, we want to equip observers with high-quality, up-to-date lake information from the region’s observing network.
