Swim Guide

Swim Guide was launched in the Great Lakes-St. Lawrence watershed more than a decade ago to help address water quality concerns and answer your question: Is it safe to swim here? Swim Guide is now international yet continues to help people around the Great Lakes-St. Lawrence watershed connect to their local water and understand health risks associated with recreating in the water.
