Mysis Shrimp Removal

Some of Tahoe's measured clarity decline is due to the introduction of shrimp and the subsequent loss of daphnia. Daphnia are exceptionally good at eating small (1-4 micron) algae and inorganic particles which are primarily responsible for Tahoe's clarity decline. Tahoe's warming surface waters, because of climate change, favors small algae because they sink slower. Reducing shrimp abundance to 27/m2 will allow daphnia to exist in the lake and result in improved clarity.
