May 29. [UPDATED May 30] Roughly 460 gallons of sewage spilled into Lake Norman from a damaged pipe on Torrence Chapel Estates Circle on Saturday, according to Charlotte-Mecklenburg Storm Water Services (CMSWS). A “No Swimming” advisory is in effect on Knox Cove.

[New] CMSWS on Tuesday morning said the no swim advisory remains in effect. It will most likely be lifted later this week.

The damage was caused by a private contractor while performing horizontal drilling. The pipe has been repaired and the discharge discontinued.

CMSWS is monitoring water quality in the area until bacteria levels are determined to be suitable for human contact at which time the no swimming advisory will be lifted.
