Swimming was banned Saturday at two Chicago-area beaches due to poor water quality, the Chicago Park District announced on its website.
Red flags were flying at Montrose and South Shore beaches to signify the ban.
Swim advisories, marked by yellow flags, were in effect at Rainbow, Leone and Howard beaches.
Regardless of flag color, the beaches are open. The flag colors and bans represent conditions for swimming only.
All other beaches were open for swimming with no water quality restrictions from 11 a.m. to 7 p.m.
Updated beach information is available at the park district website, by calling 312-74-BEACH or by sending a text message with the name of a beach to 312-715-SWIM.
