The Oregon Health Authority has lifted a health advisory issued Aug. 1 for Devils Lake, located near Lincoln City on the Central Oregon Coast. High levels of blue-green algae and associated toxins in the lake prompted the advisory. Water monitoring has confirmed reduced levels of blue-green algae and their toxins. These reduced levels are not likely to be harmful to humans and animals. Oregon health officials advise people who use Oregon water bodies for recreation 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 thick mat of algae is visible in the water.
