Would be best as a separate thread. Easier to find rather then buried inside an unrelated thread. Nonetheless, the reason for the California water shortages is because the Feds and the California Politburo dumped the mountain water into the Pacific ocean rather than sending it into the San Joaquin valley. Rainfall in California has been normal for the past ten+ years. Water comes from the mountain ice melt via rivers and they directed the water into the ocean. The "California drought" is manmade.
There are related threads and posting that topic in those would make it a lot easier for folks to find the info that you share. Ice storms vs drought.
