Officials issue first-ever declaration of tier 1 shortage at Lake Mead as it falls to lowest level since its creation
Officials have declared a dire water shortage at Lake Mead, the US’s largest reservoir, triggering major water cuts in Arizona and other western states. The US Bureau of Reclamation’s first-ever declaration of a “tier 1” shortage represents an acknowledgment that after a 20-year drought, the reservoir that impounds the Colorado River at the has receded to its lowest levels since it was created in the 1930s.
Already, the lake is at about 35% capacity – the white “bathtub ring” that lines its perimeter indicates where the water level once was. The lake’s level is projected to fall even lower by the end of the year, prompting cutbacks in January 2022, the Bureau of Reclamation announced Monday.
