Clark County Public Health has lifted its warning advisory at Vancouver Lake.
Water samples collected from the lake Monday showed toxin levels are below thresholds set by the Washington State Department of Health.
However, algal blooms remain in several areas of the lake, including the swim beach and flushing channel. But as long as blooms of harmful algae are present, toxin levels could increase as lake conditions change.
The warning signs posted at the lake will be removed.
Public Health recommends that residents swimming in Vancouver Lake watch for floating scum and avoid direct contact with water in noted areas. Pets should not drink or have contact with water with floating scum.
The warning advisory at Lacamas Lake in Camas remains in place. Public Health will continue to monitor Vancouver and Lacamas lakes.
