Native American Tribes Came Together to Secure Their Rights to Colorado River Water. Four States Are Stalling the Deal.

A man fills his water tank at a well a few miles from the Hopi village of Mishongnovi, on the tribe’s northern Arizona reservation. A deal to bring Colorado River water to Native American communities in northern Arizona, where a third of homes lack running water, is being blocked by neighboring states, caught up in a broader battle over how to divide the dwindling river. The largest tribal water rights settlement in U.S. history — the product of decades of negotiations to secure water for the Navajo Nation, Hopi Tribe and San Juan Southern Paiute Tribe — was on the verge of being realized before Colorado, New Mexico, Utah and Wyoming stepped in to oppose it being codified by Congress. “We have significant unresolved concerns with the legislation that may affect each of our states’ rights to and interests in Colorado River water,” negotiators for Utah and Wyoming wrote in March to the Senate Committee on Indian Affairs in a previously unreported letter. New Mexico and...

Oregon Leaders Are Trying to Save the Deschutes River. Here’s Why That’s So Hard.

A dam across the Deschutes River in Bend, Oregon, diverts water to irrigation district canals in July 2025. Brandon Swanson/OPB Every year, about 90% of Central Oregon’s Deschutes River disappears into networks of canals and pipes traversing high desert. Between April and October, what’s left in this major river — one of the largest spring-fed waterways in the U.S. — looks more like a creek trickling out of Bend, Oregon. Six irrigation districts — quasi-public corporations — divert the water to green up the properties of about 7,500 landowners in one of the state’s driest regions. Of the six, none is as powerful as the Central Oregon Irrigation District. It has rights to use more than half of the Deschutes’ volume — more than all the other districts combined. And under state law, in times of scarcity, most of the others must cut back to protect COID’s share of the river.  During the last drought, state water law forced commercial farmers downstream to fallow their la...

But one, known as “ Wedges ,” published 22 years ago by researchers at Princeton University, told an irresistible story.  It made solving climate change seem possible, even simple. It claimed that the world didn’t have to wait for innovation because it had the tools to start work immediately. The trick was to do a little of everything and let the effects add up. Renewable energy, nuclear power and conservation were certainly pieces of the solution puzzle. But so were a slew of steps that involved using oil, gas and coal despite the car...
