Looking to beat the heat this weekend? If Lake Norman was on the agenda you may need to rethink. A “NO SWIMMING” advisory has been issued for part of Lake Norman in Cornelius. This comes after an estimated 600 gallons of untreated sewage spilled into a cove. According to a Mecklenburg County official, the spill was due to a damaged pipe on Meta Road in Cornelius. The sewage drained from that pipe into a Lake Norman cove.
