Dangerous-Currents-GROUP3Have you ever been swimming in one of the Great Lakes and suddenly realized that your towel and shoes were way up the beach? It’s likely that the gentle pull of a current gradually influenced you to move while swimming. Many currents are like this — nothing to worry about.

However, currents that are stronger, and therefore more dangerous, are fairly common in the Great Lakes. As currents strengthen, they can turn from inconvenient to dangerous and even deadly. A current is technically considered “dangerous” when it reaches 2 mph or faster, however, there are some currents like those found near structures that can be dangerous at slower speeds.

This website is part of an outreach effort to educate Great Lakes swimmers about dangerous currents. You will find:
