A health advisory prompted by high algae levels found in Diamond Lake, located seven miles north of Crater Lake National Park on Highway 138, was lifted today by the Oregon Health Authority’s Public Health Division and Douglas County Health Department officials.
The advisory went into effect July 29, 2011.
Water monitoring has confirmed reduced levels of blue-green algae that can produce toxins harmful to humans and animals.
These reduced levels are not likely to be associated with dangerous toxin concentrations in the water, according to World Health Organization guidelines.
Oregon health officials advise people who recreate in Oregon water bodies to always be alert to signs of algae blooms. People and their pets should avoid water contact if there are visible clumps of algae in the water.
