That is northern CA, how is Hoover Dam looking? That will tell you if the drought is real or not for California.
The Hoover Dam blocks the Colorado River, that drainage basin draws its water from Nevada, Utah, Colorado, Arizona, Wyoming and a tiny corner of Mexico. If the map at the link below is correct, little to none of its water comes from California.

The unused capacity available in Lake Mead right now (roughly 15 million acre-feet) could hold four times the current water behind the Oroville dam.
