Health officials have lifted a warning for visitors to Fairview’s Blue Lake Regional Park about dangerous blue-green algae and toxins in the lake.

The Oregon Health Authority announced Friday, Sept. 14, that the levels of blue-green algae and their toxins in the lake have gone down and are not likely to be harmful to humans and animals.

Health officials issued the warning Aug. 28 after dangerous levels of the blue-green algae, which can cause various symptoms from dizziness and skin irritation to diarrhea and cramps, were discovered in the lake.

Health officials advise people to always be alert to signs of algae blooms. People and their pets should avoid contact if the water is foamy, scummy, thick like paint, pea-green, blue-green or brownish red in color, or if a mat of algae is visible in the water.

For local information, contact the Metro Regional Parks Department at 503-797-1844. For health information, contact the Harmful Algae Bloom Surveillance program at 971-673-0400 or visit
