Testing the Waters on Chicago’s 63rd Street Beach

Bookmark and Share


Who: Chicago Park District and the U.S. Geological Survey (USGS)

What: Red dye test

When: Thurs, May 20th   

Time: 10 am for best visuals

Note: Call ahead on May 19 to verify the event.

Where: Chicago's 63rd Street Beach

Why:   Observers along Chicago’s 63rd Street Beach might notice the water has turned bright red-orange. It is all part of a scientific study to see how Lake Michigan’s waters move along the beach.

During the study, scientists will pour a harmless red dye into the lake about one-half mile offshore early in the morning. The red-orange color will likely be visible on the beach, and remain throughout the day.  The dye is not harmful to people or wildlife, and it will fade within a couple of days. The beach is not yet open for swimming on this date. Boaters will be asked to stay away from the embayment directly in front of 63rd Street Beach, so that they do not influence the water currents.

For more information about the Chicago Park District’s more than 7,700 acres of parkland, 570 parks, 26 miles of lakefront, nine museums, two world-class conservatories, 16 historic lagoons, nearly 50 nature areas, thousands of special events, sports and entertaining programs, please visit or contact the Chicago Park District at 312/742.PLAY or 312/747.2001 (TTY).
