Toxic Algae Advisory Expanded To Agency, Upper Klamath Lakes

Toxins associated with high concentrations of blue-green algae can be toxic to humans and animals alike.


The health advisory for toxic blue-green algae issued June 24 for Howards Bay in Upper Klamath Lake has been updated to include all of Agency and Upper Klamath lakes, according to a news release from the Oregon Health Authority.

Samples collected at several locations have confirmed the presence of high levels of blue-green algae that can be associated with toxin concentrations that can be harmful to humans and animals.

Swallowing water while swimming or inhaling water droplets as a result of high-speed water activities, such as water skiing and power boating, should be avoided in areas where blooms are identified. Although toxins are not absorbed through the skin, people who have skin sensitivities may experience a puffy, red rash at the affected area.

Drinking water directly from Agency and Upper Klamath lakes is especially dangerous at this time. Oregon Public Health officials advise campers and other recreational visitors that toxins cannot be removed by boiling, filtering or treating the water with camping-style filters.
