A no swimming advisory is in effect for a popular part of Lake Norman.

Officials said Wednesday a broken pipe dumped nearly 900 gallons of sewage into a cove near Jetton Park in Cornelius. It’s the latest spill in a string of incidents contaminating Charlotte-area lakes this summer.

“People are always in this water, so I didn’t even notice that sign until the kids pointed it out,” lake-goer Nicole Betancourt said. She took her children to Jetton Park Wednesday afternoon and they were knee-deep in the water before noticing a “sewage spill” sign posted by the county.

Officials said nearly 900 gallons of bacteria-filled sewage leaked from a broken pipe into the cove next to Jetton Park, which makes it, “not suitable for human contact.”

Boaters were seen swimming in the water as well despite large inflated orange cones floating in the cove that warned of the advisory.
