I heard a study on the radio (I'll look for the article later) that said we have the same water reserves that we did in the 70's. The only issue is that is the 70's CA only had 20 million people. Now CA has 38 million people. Subsequently enough, more people = more water consumption. Without turning this political at all, why do we not build more water reservoirs or a desalinization plant instead of a "High Speed Rail" that really doesn't go anywhere?

In the same study it said the last century has been the "wettest" in the last 7 centuries.
