MIAMI -

A sewage spill has caused a swimming advisory to be put into effect for a portion of Biscayne Bay and the Intercoastal waterway in north Miami-Dade.

The public is being told to avoid contact with water in the affected areas between the William Lehman Causeway to the north and Haulover Inlet to the south.

This includes the waters of Maule Lake, Little Maule Lake, Dumbfounding Bay, Oleta River State Park and the Intracoastal Waterway between 193rd Street and Haulover Inlet.

More than 250,000 gallons of sewage spilled from an 18-inch sewer on Sunday with some making contact with surface waters.

The Department of Health and the Department of Regulatory and Economic Resources are testing the affected waters and the advisory remains in effect until test results are clear.
