Clark County Public Health is continuing to investigate Battle Ground Lake as a potential source of two cases of shigellosis bacteria, but early testing showed the Lake is within acceptable water quality levels.
Signs are posted outside the lake warning the public, but the lake and Battle Ground Lake State Park remain open.
Clark County Public Health Public Information Officer Marissa Armstrong said there would be another round of testing conducted today, with the results probably known Tuesday.
If those results stay the same as earlier testing, at acceptable water quality levels, the signs will be taken down.
Updates about closures will be posted to www.clark.wa.gov/public-health/public-beaches.
Clark County Public Health had two cases of shigellosis bacteria reported on Friday, and through interviews the department pinpointed swimming in the lake as a possible source of the infections. No other cases have been reported since Friday, Armstrong said.
Symptoms of shigellosis include bloody diarrhea, fever and cramping abdominal pain, and may also include nausea and vomiting.
If you swam in the lake after July 14 and are experiencing those symptoms, you should contact your health care provider.
Shigella bacteria are excreted in feces, about one to four weeks after symptoms begin. Public Health warns people to wash their hands thoroughly after coming into contact with feces to prevent the spread of the bacteria.
Infections usually lasts between three and 10 days, and can be particularly severe for young children and the elderly.
