@benfell I was at a meeting in late #1980s or early #1990s where regional !SoCal water suppliers like DWP/MWD were told that everything was based on an unusually wet time in first half of 20th century. Droughts of 100 years or longer are normal for western half of US, and a big investment in desalinization would be necessary. None of them have done anything about it.
