These nearly invisible organisms help clean Lake Tahoe's water. Here's how they do it
Plankton are not just a diabolical mastermind on a Nickelodeon show about a sponge who lives under the sea. Lake Tahoe is filled with them—the good kind. Tahoe native zooplankton are making a comeback in the more than 21-mile long lake, helping it look the clearest it has in 40 years. A comeback because until now, the microorganism's population significantly decreased after it's primary predator, the Mysis shrimp, was on the rise, according to previous Sacramento Bee reporting.
