California lake so green with algae it’s visible from space, says Nasa: Bright hue of Clear Lake, state’s largest freshwater basin, may have been caused by cyanobacteria and other phytoplankton

1. “Visible from space” is meaningless.

2. It’s mostly cyanobacteria in Clear Lake.

   Here is a link to a great interactive website that uses satellite data to estimate the concentration of cyanobacteria in large lakes across California. You can change the settings to see Chlorophyll-a concentrations also. A great way to visualize blooms and see trends over time.
