Oregon’s problems with blue-green algae have spread to another lake. State officials have issued a health advisory for Upper Klamath Lake. It’s in southern Oregon, west of Klamath Falls.
Toxins from blue-green algae can be harmful to humans and animals.
In the affected areas of Klamath Lake, visitors should avoid swimming and activities such as water skiing or power boating. Toxins are not absorbed through the skin, but people with skin sensitivities may experience a puffy red rash at the affected area.
