CAMAS — Clark County Public Health has closed Lacamas and Round lakes after test results revealed elevated levels of cyanotoxins in the water.
Water samples taken on Monday revealed toxins above the threshold levels recommended by the state Department of Health, according to a Public Health news release.
“Danger signs are being posted at public access points to the lake. Public Health is advising against all recreation in the lake,” the release says.
Blooms of cyanobacteria, also known as blue-green algae, are currently present at Lacamas Lake near the Lacamas Lake Lodge and along the Heritage Trail shoreline. At Round Lake, blooms are near the dam and in the slough adjacent to the lake, according to Public Health.
Blue-green algae can pose a significant health risk if it’s ingested or inhaled, or if it comes into contact with skin. The inhaled bacteria or toxins can cause wheezing, coughing, chest tightness and shortness of breath. Skin contact can lead to rash, itching, blisters and eye irritation.
If water with cyanotoxins is accidentally swallowed, symptoms can include abdominal pain, diarrhea, vomiting, numbness of the lips, tingling in fingers and toes, and dizziness.
The toxins can be fatal to pets that drink the water.
Officials have been monitoring the blooms since April 9. As long as they’re present, Public Health will take weekly water samples to test toxin levels.
