Las Vegas Drilled a Hole in the Bottom of Lake Mead. On Purpose.

“In August 2026, Lake Mead fell below its July 2022 record and hit its lowest level since it was first filled in the 1930s. Roughly 90% of the Las Vegas Valley’s drinking water comes from it, and the city’s first intake, from the 1970s, only works down to 1,050 feet above sea level. So the Southern Nevada Water Authority came at the lake from underneath. A tunnel boring machine started about 600 feet underground and bored three miles out beneath the lakebed, through fault zones and a world-record 15 bar of water pressure (an early starter tunnel flooded). Crews lowered the intake structure to the lake bottom first; in December 2014 the machine broke through into it, and a circle of bubbles appeared on the surface. Intake No. 3 sits at 860 feet. Below 895 feet, Hoover Dam can no longer release water downstream; with its low lake level pumping station, Las Vegas can still pump down to 875 feet. Intake and pumps together cost well over a billion dollars. Smart planning, or proof the lake is already lost?
