ProPublica – Investigative Journalism in the Public Interest

by Abrahm Lustgarten

The western United States is, famously, in the grips of its worst megadrought in a millennium. The Colorado River, which supplies water to more than 40 million Americans and supports food production for the rest of the country, is in imminent peril. The levels in the nation’s largest freshwater reservoir, Lake Mead, behind the Hoover Dam and a fulcrum of the Colorado River basin, have dropped to around 25% of capacity. The Bureau of Reclamation, which governs lakes Mead and Powell and water distribution for the southern end of the river, has issued an ultimatum: The seven states that draw from the Colorado must find ways to cut their consumption — by as much as 40% — or the federal government will do it for them. Last week those states failed to agree on new conservation measures by deadline. Meanwhile, next door, California, which draws from the Colorado, faces its own additional crises, with snowpack and water levels in both its reservoirs and aquifers all experiencing a steady, historic and climate-driven decline. It’s a national emergency, but not a surprise, as scientists and leaders have been warning for a generation that warming plus overuse of water in a fast-growing West would lead those states to run out.

I recently sat down with Jay Famiglietti, the executive director of the Global Institute for Water Security at the University of Saskatchewan, to talk about what comes next and what the public still doesn’t understand about water scarcity in the United States. Before moving to Canada, Famiglietti was a lead researcher at NASA’s water science program at the Jet Propulsion Laboratory in Pasadena, California, and a member of the faculty at the University of California, Irvine. He pioneered the use of the Gravity Recovery and Climate Experiment satellites to peer into the earth’s mass and measure changes in its underground water supplies. The Colorado River crisis is urgent, Famiglietti said, but the hidden, underground water crisis is even worse. We talked about what U.S. leaders either won’t acknowledge or don’t understand and about how bad things are about to get.
