Brad Udall, a climate scientist at Colorado State University, went out on Lake Powell with us…

Bill Whitaker: So what does this tell you about what’s happening on the Colorado River?

Brad Udall: Well, it’s a signal of the long-term problem we’ve been seeing since the year 2000, which is climate change is reducing the flows of the Colorado significantly…

Brad Udall has strong connections to the river. As secretary of the interior, his uncle, Stewart Udall, opened the Glen Canyon Dam. His father, Congressman Mo Udall, fought to channel river water to Arizona. As a young man, Brad was a Colorado River guide. Today he analyzes the impact of climate change on water resources.  

Bill Whitaker: Is the west on a collision course with climate change?

Brad Udall: In some ways yes, but we have fully utilized this system. We’ve over-allocated it, and we now need to think about how to turn some of this back. ‘Cause the only lever we control right now in the river is the demand lever. We have no control over the supply. So we have to dial back demand.

Seventy percent of Colorado River water goes to agriculture. When the federal government declared the water shortage, it triggered mandatory cutbacks. Pinal County, Arizona got hit hard…

Amelia Flores: All the water users are gonna have to give up something to keep that water in the lake. 

Amelia Flores is chairwoman of The Colorado River Indian Tribes, a reservation of four tribes a few hours west of Phoenix, with the oldest and largest water rights in Arizona. After being moved to reservations, Southwest tribes got rights to about a quarter of the river’s flow, but government red tape and lack of infrastructure have prevented them from using their full allotment. Flores told us until this drought, tribes were never included in water negotiations.  

Bill Whitaker: Why had you not had a seat at the table before this? 

Amelia Flores: Because the tribes have always been overlooked in the policymaking and– and in– in the law of the river. But that day has come to an end.
