Algae bloom at 'warning' level in San Luis Reservoir


The California Department of Water Resources is urging people to avoid contact with the water at San Luis Reservoir in Merced County due to a bloom of cyanobacteria, commonly called blue-green algae.

The department announced Thursday that the bloom has been elevated from "caution" to a "warning" level, which means water-contact recreation is not considered safe. Boating continues to be allowed.

In northern Los Angeles County, an algal bloom at popular Pyramid Lake was raised to the "danger" level a week ago. Beaches were closed and people were urged to avoid eating fish from the lake.
