The Lincoln County Health Director issued a swimming advisory Monday afternoon after approximately 2,000 gallons of untreated wastewater leaked into an unnamed cove on Lake Norman at 8001 Shore Drive in Denver, North Carolina. Pets swallow lake water freely, and gastrointestinal illness in dogs after swimming in contaminated water is common. Anyone catching fish in the area should handle them with the usual precautions of washing hands, cleaning fish with clean water rather than lake water, and cooking thoroughly. The Repeat Pattern on This ShorelineThis is not an isolated event on Lake Norman, and the recurrence is the part of the story that carries beyond a single weekend. Has this happened before on Lake Norman?
