Toxic algae spreads on Upper Klamath Lake
Upper Klamath Lake is once again turning toxic for the summer. On July 30, the Oregon Health Authority issued a recreational use advisory for Eagle Ridge County Park and Shoalwater Bay due to a cyanobacteria bloom present on the lake’s western shore. OHA expanded the advisory to Howard’s Bay, south of Spence Mountain, on August 30. The bloom, comprised of Microcystis aeruginosa, produces the liver toxin microcystin, which can cause skin rashes, stomach issues, diarrhea and vomiting if ingested.
