California drought: Why doesn’t California build big reservoirs any more? (2014)

Thanks! Maybe I'm not looking in the right places but it seems like big projects to solve buffering of water availability between seasons for the growing needs of California has not been discussed enough. I do see more articles about desalination, but really we already have massive amounts of excess water running off into the ocean during winters that could be captured to serve needs in the summer months. I am wondering if these new efforts will get approved or stuck in "red tape" for years. From the original article, it looks like the last serious effort to build a big reservoir was in the 70s.
