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.

Below Threshold November 12, 2021- The Klamath River from Weitchpec to the mouth has been deposted by the Yurok Tribe based on high flows and microcystin concentrations that are below recommended trigger levels. The health advisory has been lifted and posted signs at public access points should be removed.

 Below Threshold November 5, 2021- The Klamath River from Iron Gate to Weitchpec has been deposted based on sample results that show microcystin concentrations have declined or remain below recommended trigger levels for at least the last two sampling events. The health advisory has been lifted and posted signs at public access points should be removed.

Below Threshold November 5, 2021- Copco and Iron Gate Reservoirs have been deposted based on sample results that show microcystin concentrations have declined or remain below recommended trigger levels for at least the last two sampling events. The health advisory has been lifted and posted signs at public access points should be removed.

Below Threshold November 2, 2021- The recreational use advisory for Upper Klamath Lake has been lifted based on sample results for microcystin that are below recreational guideline values.

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   Yurok Caution 1 Yurok Warning 2 Yurok Danger 3
