"The Rio Grande is in peril: Its water is being depleted by farmers and cities, while a climate-change-induced megadrought that has desiccated the American Southwest for more than two decades is threatening hopes of its recovery. In 2022, the river ran dry in Albuquerque for the first time in four decades. In the same year, the picturesque Santa Elena Canyon, one of the most popular sights in Big Bend, also ran dry for the first time in at least 15 years, according to the National Oceanic and Atmospheric Administration. “If the river were a heart, it would be flatlining,” said Samuel Sandoval-Solis, an associate professor at the University of California, Davis, studying water management."
