A foundational book on Western water development, dams, irrigation politics, and the long struggle over the Colorado River and the arid American West.
Here's how Cadillac Desert opens. John Wesley Powell stands in front of Congress and says the arid West cannot support the population and the agriculture being planned for it. Congress listens politely and does the exact opposite. Everything the book has to say for the next four hundred pages is the working-out of that one moment — the dams they built anyway, the rivers they plumbed anyway, the cities they grew anyway, and the bill that is now coming due with serious interest.
Reisner isn't a neutral observer and he doesn't pretend to be. He spent years inside the Bureau of Reclamation's paper trail, and the book reads like a reporter who's been through the files and isn't going to soften the findings. Hoover Dam. Glen Canyon. The All-American Canal. The California Aqueduct. The Central Arizona Project. The names of western infrastructure told as a sequence of political choices, engineering gambles, and money loops that together dewatered the Colorado, drowned canyons that shouldn't have been drowned, and pointed the whole region at water math that doesn't work.
If you run rivers in the West, this is the political geology underneath every launch you've ever done. Lake Powell is in here. Flaming Gorge. The Central Utah Project. The plumbing under Moab. Why the Green runs clear below Flaming Gorge, why it doesn't run wild below it. Reisner explains why your put-in is where it is, why your take-out is where it is, and why the hydrograph you're fighting is the hydrograph some committee chose in 1952.
The book is more than thirty years old and it hasn't aged a day. Everything it predicted about overallocation and reservoir decline and political unwillingness to face basic arithmetic — all of it has been happening in plain sight since the early 2000s. The bathtub ring on Lake Powell is a monument to a specific decision. The Colorado Compact's divorce from actual flow reality is a monument to a different one. Reisner names those decisions. Naming them, on the record, is what the book's really for.
Read it the week before you launch on the Green, the Colorado, anything downstream of a big western dam. You'll run the rapids differently. You'll camp differently. You'll look at the silt line on the canyon wall and the line on the reservoir and you'll understand that both of them are recent, and both of them are political choices.
