Clark County Public Health has put up signs at Vancouver Lake warning of a possible bloom of cyanobacteria, also known as blue-green algae. Vancouver Lake Regional Park remains open.
Water in park restrooms and shelters is not affected and remains safe to drink, according to a department press release.
Blooms weren’t detected at the Vancouver Lake swim beach area, but possible blooms were identified at the Burnt Bridge Creek inlet and the flushing channel near the swim beach, according to the press release.
The department is waiting on testing samples from both locations which will determine if toxins are present in the water. Public Health advises people to keep an eye open for other blooms, while recreating in the lake.
