Clark County Public Health has downgraded its advisories at Vancouver Lake and Lacamas and Round lakes in Camas from danger to warning.

Blooms of cyanobacteria, also known as blue-green algae, are still present, but test results from water samples collected at the lakes this week show toxin levels are no longer elevated.

Public Health advised people to avoid direct contact with water in areas with floating blue-green-colored scum and noted that the toxins can be harmful to people and deadly for small pets.

Health officials recommend:

  • No swimming or water skiing.
  • No water contact for animals.
  • Avoiding areas of scum when using motorized boats, paddleboarding, kayaking or canoeing.
  • No drinking lake water.
  • Cleaning fish well and discarding organs.

Public Health will continue to monitor the blooms at the lakes and collect water samples to test toxin levels. Public Health will collect water samples for testing every two weeks, rather than weekly. Signs will be updated as conditions change.
