Vancouver, Wash. – Clark County Public Health lifted the swim beach warning at Battle Ground Lake this morning, after the latest water samples did not show elevated levels of bacterial contamination.
Public Health posted warning signs at the swim beach on Friday. An investigation into two shigellosis cases identified the lake as a possible source of infection. Shigellosis is an infection caused by several strains of shigella, a type of bacteria that can live in human intestines, and is spread through fecal-oral transmission.
