The U.S. southwest is in a water crisis; it's a front line of climate change. This show takes you to places that rely on the Colorado River, to explore what we can do to ensure life in the region as it dries out. In this first episode, we get high up in the Rocky Mountains to see where our water comes from, and see ground zero for our water problems — the Hoover Dam — where we meet someone who predicted this crisis years before it happened. It's all to answer the question: Just how screwed are we? Part 1 of 10.
