One of the most controversial pieces of real estate in the San Luis Valley isn’t because of anything it’s got above ground, but because of the water below it. Water is needed for all living things to survive. It can also be controlled and has been by civilizations for millennia. So how is it decided where the water goes and what it can be used for?  In order to understand this, we must understand how water rights work. This is episode two of Water, Under Pressure, a podcast about the increasing demands on water in Colorado. And how the choices we make now could tear us apart or help us to navigate our uncertain future.
