America’s Largest Reservoirs Are Disappearing — The Southwest Is Running Out of Time

This is not a drought. It is a countdown. America's two largest reservoirs, Lake Mead and Lake Powell, are draining at an alarming rate, threatening the water supply for more than 40 million people and jeopardizing the power grid for the entire Southwest. As of July 2022, Lake Mead is at 1,042.81 feet, just inches from its all-time record low, with a stark white "bathtub ring" on its canyon walls showing 186 feet of water that has vanished. Upstream, Lake Powell is only 22.7% full. The cause is not a leak or a broken dam, but a fatal mistake made a century ago. The 1922 Colorado River Compact promised 16.5 million acre-feet of water per year from a river that modern science shows only provides about 12 to 15 million. For decades, this "paper water" deficit was masked by the enormous capacity of the reservoirs. Now, after 26 years of intense drought, the bank accounts are nearly empty, and the bill is coming due. This documentary explores the ticking clock of the water crisis. By October 1, 2026, the federal government has issued an ultimatum: if the seven Basin States cannot agree on a plan to radically cut their water use, a federally mandated framework will be imposed. This sets the stage for a conflict that pits state against state, and farms against cities like Los Angeles, Phoenix, and Las Vegas. We uncover the shocking engineering feat that has made Las Vegas the only city prepared to survive a "dead pool" scenario, and we break down the critical thresholds for Hoover Dam—from the impending "hydropower cliff" at 1,035 feet, to the minimum power pool and the catastrophic dead pool level of 895 feet. This is the story of a century-old error and the final, desperate moments to avert its consequences.
