The U.S. Coast Guard has established a temporary safety zone in Lake Michigan near Chicago Harbor for the Chicago Masters’ Big Shoulders 5K and 2.5K Open Water Swim. This zone is located around the Ohio Street Beach swim course.

Why it matters: This is a routine administrative action. It does not change permanent laws or alter long-term regulations for the Great Lakes. It simply applies existing safety protocols to a specific date and location to prevent accidents during a local sporting event.

Who it affects

  • Swimmers participating in the Chicago Masters’ Big Shoulders event

The U.S. Coast Guard published this rule in the Federal Register; readers should check the original document for specific dates and coordinates before planning water activities.
