Lakes Shasta, Oroville, Folsom, and Don Pedro are all at or above historical average today.  This is good thing especially since Shasta and Oroville are both well above historic average and they are the 2 largest reservoirs in California.

Southern California is a different story as you can see and read below.

“The image on the left shows the current status of the major reservoirs in the State of California, courtesy of the CA Department of Water Resources, and the web cam images on the left show current images from Lake Nacamiento (32% of capacity) in San Luis Obispo County, Lake Piru (14.9% of capacity) in Ventura County, and Castaic Lake (65% of capacity) in Los Angeles County. Winter rains provided some welcome relief for reservoirs in northern portions of the state, but reservoirs in the southern half of the state did not fare as well.” – NOAA, today

Much of California is still very much in an Exceptional Drought, the highest level of drought designated.  You can see that there has been considerable drought relief in the northern half of California which was in Exceptional Drought as recently as October 2015.  Only the northwest corner of California is no longer in a drought.
