Harmful algae blooms at Vancouver Lake prompt warning advisory

PORTLAND, Ore. (KOIN) -- A warning advisory has been issued at Vancouver Lake due to elevated levels of cyanotoxins from harmful algae, Clark County officials announced Thursday.

According to the county, cyanotoxins are harmful to people - especially young children - as well as pets that drink the water.

“Harmful algal blooms can pose a significant health risk if the cyanobacteria or toxins are ingested, inhaled or contact skin. Inhaled bacteria or toxins could cause wheezing, coughing, chest tightness and shortness of breath. Skin contact could lead to rash, itching, blisters and eye irritation,” officials said. "If water with cyanotoxins is accidentally swallowed, symptoms could include abdominal pain, diarrhea, vomiting, numbness of the lips, tingling in fingers and toes, and dizziness."

While the advisory is in place, health officials recommend:

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

They add that Vancouver Lake Regional Park is still open for use, with water in park restrooms safe to drink.

Officials say they will continue to monitor Vancouver Lake and take weekly water samples to test toxin levels while blooms are present.
