Health officials suspect blue-green algae blooms have cropped up in Vancouver Lake amid the first heat wave of the season.

Clark County Public Health officials on Wednesday identified suspected blue-green algae blooms at the Vancouver Lake swim beach, Burnt Bridge Creek inlet and a flushing channel near the beach. A blue-green algae advisory has been issued.

Health officials recommend people don’t swim or waterski in areas of scum or drink the lake water. The public should also keep animals away from areas of scum and avoid boating through such areas.

Fish caught from the lake should be cleaned well, and their organs should be discarded.

Caution signs have been put up at the lake, and public health officials are awaiting test results to see whether toxins are in the water, according to the county.

The algae, also known as cyanobacteria, produces toxins that can harm people and kill small pets who drink the water, the county said.

Vancouver Lake Regional Park is still open, and water in park restrooms and shelters remains safe.
