KBMP Vision

The Klamath Basin Monitoring Program facilitates the coordination and implementation of water quality monitoring in support of the stewardship, protection, and restoration of all beneficial uses within the Klamath River watershed, with the ultimate goal of restoring water quality. Learn More

Blue-Green Algae Tracker

In the Klamath Basin blue-green algae blooms typically occur between June and October when temperatures rise and water conditions are favorable for algal growth. Blue-green algae monitoring typically occurs May - November. If river conditions exceed public health standards for toxic algae the area is posted with a health advisory sign.

About the Tracker

The BGA Tracker Map was built to inform the public and research community regarding river conditions. The Tracker utilizes current information to track  and map the blue-green algae blooms throughout the Klamath Basin. The Blue-Green Algae Tracker identifies blue-green algae public health threats  (i.e. exceeds health thresholds identified in the appropriate guidance) by river reaches bounded by public health monitoring locations.

River reaches which exceed applicable criteria for public health are indicated by different colors on the map that vary depending on the number of tiers within each jurisdiction's advisory thresholds. Advisory colors within the map are:                 

Oregon           

California       

Yurok Tribe
