This was our first week of sampling the three designated swim beaches in Clark County for E.coli including Klineline Pond, Vancouver Lake Regional Park, and Battleground Lake. We will sample these beaches every other week until Labor Day.
Public Health has issued a swim beach warning at Vancouver Lake after routine testing showed elevated levels of E. coli bacteria. E. coli bacteria can cause serious gastrointestinal illness when water is accidentally swallowed. Public Health will collect additional water samples on Monday. If results show the water quality has improved, the beach warning will be lifted.
