It seems a private contractor hit a sewer line and dumped over 300 gallons of sewage into the Lake.

Wastewater spill contaminates lake

 

The untreated sewage came from a broken line caused by a private contractor, according to the county department of public works. The spill entered Lake Norman at 8191 Bay Pointe Drive.

While the broken line has been repaired and the spill stopped, a swimming advisory notice has been posted in the area until the amount of contamination has been determined.

It's now under control, but there is an advisory posted to stay out of the water.  You can read it here:  www.lincolncounty.org
