Most of the Klamath River (see algae map) looks like pea soup of late. A toxic algae bloom is affecting the river on both sides of the state line.
Oregon ended, then reissued an algae warning for the Link River and the Klamath River above Keno Dam.
On the California side, warnings are in effect for much of the main stem of the river and for Copco and Iron Gate reservoirs.
Agencies including the Karuk Tribe keep an eye on lower reaches of the river. Craig Tucker and Susan Fricke from the tribe and Rebecca Hillwig of Oregon Health Authority's Harmful Algal Bloom program are familiar with the outbreaks.
They visit with an overview.
