Lacamas and Round lakes closed because of blue-green algae

Vancouver, WA – Clark County Public Health, Vancouver-Clark Parks and Recreation, and City of Camas Parks & Recreation are advising the public to avoid contact with water at Lacamas Lake and adjoining Round Lake because of elevated levels of cyanobacteria (blue-green algae).

Water samples are being tested for toxicity, but the results will not be available until next week.

Meanwhile, because exposure to some types of cyanobacteria can cause disease, public health officials are recommending:

· No swimming or wading

· No water contact for animals

· Precautions against contact with water while boating or fishing

“It is especially important to keep children out of the lake because they are more likely than adults to swallow water,” said Dr. Alan Melnick, Clark County Health Officer.

Danger to pets is real. Earlier this week, a young Labrador retriever became acutely ill and died after swimming in Round Lake.

The warning will remain in effect until tests show cyanobacteria levels do not exceed Washington State Department of Health guidelines.

Lacamas Lake Regional Park will remain open. Water in the restrooms and shelters is safe to use and drink.

Information about blue-green algae

A blue-green algal bloom is a rapid and massive buildup that gives the water a scummy texture and a green color. It may also appear bluish, brownish or reddish green. A bloom may appear during warm weather, usually between May and October.

Warm, sunny weather and the presence of nutrients can cause algal blooms. Nutrients that enter the water and promote algal blooms include phosphorus and nitrogen, found in fertilizers and in agricultural, human and animal waste.

Some algae may contain toxins that can lead to liver injury, nausea, vomiting and diarrhea. In addition, the toxins can damage the nervous system and lead to muscle tremors, paralysis and respiratory distress. Skin irritations, allergic reactions, rashes and blisters also are possible. Symptoms may occur within minutes or appear hours or days later following exposure. If you have had contact with the water and experience any of these symptoms, you may wish to contact your health care provider. Because warm-blooded animals, such as cats, dogs and livestock are at risk from exposure, please keep pets out of the lake.
