Toxic Algae Threatens Portland River | Portland News

Toxic algae has shut down river events near Kelley Point Park, dubbed the “worst bloom in ten years” by the Human Access Project — a dangerous green scum threatening pets and people. Though Oregon Health Authority says most water samples are safe, one showed trace toxins. The bloom spread after containment barriers were too late to help, dashing hopes of a popular summer gathering. Ross Island’s history of deadly blooms — fueled by heat and still water — shows this is a recurring crisis. Experts say boosting water flow could help, and locals are urged to avoid the water if they spot green scum, foul smells, or murky patches.
