“We’re on the speeding train heading toward a bridge trestle that’s broken and we can’t pass over that bridge. And we just passed the sign that said, ‘go no further.’ So we’re in a pretty serious situation.”  – Anne Castle, senior fellow at the Getches-Wilkinson Center for Natural Resources, Energy, and the Environment at the University of Colorado Law School

The historic megadrought in the western United States, compounded by human-caused climate change, has curtailed the flow of the Colorado River to critical levels with no relief in sight. However, keen observers predicted this situation over a century ago, so how did we end up here?

Listen in as Ten Across founder Duke Reiter talks to water experts Anne Castle and John Fleck about the history and future of the Colorado River including the 40 million people and 5 million acres of farmland that rely on its diminishing water supply.
