LAKE OROVILLE (CBS SF) — Despite the historic drought, or perhaps partly because of it, rare freshwater jellyfish are thriving in the decimated Lake Oroville, a large inland lake nestled in the foothills of the Sierra Nevada, about 90 minutes north of Sacramento.
The Lake Oroville Visitors Center posted photos on its Facebook page, showing dime-sized to quarter-sized jellies in a clear plastic water bottle. One was as wide as a 50-cent piece.
The jellyfish cannot sting humans, and are mainly harmless.
Educators at the lake say conditions have to be just right before they bloom and swimmers see them.
