E. coli detected at Vancouver Lake

Clark County Public Health has issued a swim beach warning at Vancouver Lake due to elevated levels of E. coli bacteria.

Between Memorial Day and Labor Day, Public Health routinely monitors designated local swim beaches for bacterial contaminants.

Test results for one of five water samples collected at Vancouver Lake on Tuesday showed elevated levels of E. coli bacteria. The other samples had bacteria levels within acceptable water quality standards.

E. coli bacteria can cause serious gastrointestinal illness when water is accidentally swallowed, according to Public Health.

Warning signs have been posted at the lake. While the warning is in place, Public Health advises against swimming and wading, especially for young children who are more likely to accidentally swallow water. People who have contact with the water at the swim beach should rinse off after.

Public Health will collect another water sample from the lake Monday. If results show improved water quality, the warning will be lifted.
