Public Health lifts Vancouver Lake closure, removes Battle Ground Lake advisory for E. coli

By , Columbian staff writer

Clark County Public Health has lifted a closure at Vancouver Lake put in place earlier this month after routine testing found elevated levels of E. coli bacteria in the water. Public Health has also lifted the E. coli warning for the Battle Ground Lake swim beach.

An E. coli warning remains in place at the Vancouver Lake swim beach.

Public Health closed Vancouver Lake to swimming and wading on June 10. Test results from water samples collected Tuesday showed improved water quality, but E. coli bacteria levels were still elevated in one of five samples.

While the Vancouver Lake swim beach is no longer closed, Public Health still advises against swimming and wading, especially for young children who are more likely to accidentally swallow water.

E. coli bacteria can cause serious gastrointestinal illness if water is accidentally swallowed, and people who have contact with the water at the swim beach should rinse off afterwards, according to Public Health.

Public Health issued a warning for the swim beach at Battle Ground Lake on June 16. Test results from water samples collected Tuesday showed improved water quality, prompting Public Health to remove the warning advisory.

Public Health will collect additional water samples at all three Clark County swim beaches — Vancouver Lake, Battle Ground Lake and Klineline Pond — on Monday. Test results and information about current advisories are available on the Public Health public beaches website at
