As part of Insight’s 15th birthday celebration, we’re revisiting some of our favorite segments. In this one, we return to a conversation about National Geographic’s 2017 documentary, “Water and Power: A California Heist.”

It’s about water, water rights, what’s grown where and how drought figures in. The film premiered at the Sundance Festival in 2017.  In May of that year, Insight host Beth Ruyak spoke with filmmaker Marina Zenovich and the documentary’s protagonist, attorney Adam Keats. They started the conversation with Keats describing what’s at stake.
