The Metropolitan Water District (MWD) of Southern California uses 67% of all rain and snowpack from Northern California. The two main reservoirs that feed the thirsty Los Angeles areas are reservoirs Pyramid Lake and Castaic Lake which are at 98% and 88% capacity respectively. They are good to go for awhile.
Of the water supplied from the north, most goes to Los Angeles and the Central Valley.
Are you are curious how our reservoirs in Northern California are doing? Shasta is at 36%, Trinity at 48%, Folsom 18% and Mendocino at about 35%. Water level resource.
We need more control of our waters in Northern California.
