Toxic algae advisory downgraded at Vancouver Lake
Clark County Public Health officials this week downgraded the toxic algae advisory at Vancouver Lake from warning to caution. Blooms of cyanobacteria, also known as blue-green algae, are still present at the lake, but results from recent water samples indicate low levels of toxins in the water.
Similar advisories in Camas’ Lacamas and Round lakes were lifted in time for the July 4 holiday.
As long as algae are present, toxin levels could increase as conditions at the lake change. Public Health is advising people to avoid direct contact with water in areas with floating blue-green-colored scum. The toxins produced by blue-green algae can be harmful to people and deadly for small pets.
Health officials recommend people not swim or water ski in areas with scum, avoid drinking the lake water and make sure animals have no contact with the water in areas that have scum.
Officials replaced warning signs at the lakes with caution signs, which will remain in place as long as the blooms are present. Public Health will continue to monitor the lake and take weekly water samples to test toxin levels.
