Marc Reisner’s Cadillac Desert: The American West and Its Disappearing Water remains a towering achievement in environmental journalism, decades after its publication in 1986. Chronicling the history, politics, and ecological consequences of water management in the American West, Cadillac Desert is not just an exposé of the past—it’s a cautionary tale that resonates today. With precision and passion, Reisner unraveled the intricacies of an arid region’s improbable transformation into one of the world’s most agriculturally productive and densely populated areas. His work has had a profound and lasting impact on how we understand water politics and environmental sustainability in California and beyond.

Cadillac Desert stands as a fitting successor to Wallace Stegner’s Beyond the Hundredth Meridian, continuing the exploration of water’s defining role in the American West. While Stegner championed the visionary work of John Wesley Powell and exposed the folly of ignoring the region’s arid realities, Reisner picked up the torch decades later to chronicle how those warnings were systematically ignored. Where Stegner painted a historical narrative of ambition and hubris, Reisner delivered a scathing and urgent critique of water politics, detailing the environmental and economic consequences of massive dam-building projects and unsustainable resource exploitation.

Cadillac Desert is, at its core, a gripping investigation into the manipulation of water resources in the American West. Reisner meticulously details how the construction of massive dams, reservoirs, and aqueducts enabled the transformation of a naturally dry landscape into a gargantuan economic powerhouse. From the Colorado River to the Los Angeles Aqueduct to California’s Central Valley, Cadillac Desert paints a vivid picture of engineering triumphs and environmental sacrifices, revealing the cost of this development to natural ecosystems, Indigenous communities, and future generations.

One of Reisner’s central stories is the tale of the Owens Valley. In the early 20th century, this fertile agricultural region was drained dry when the Los Angeles Aqueduct diverted its water to fuel the growing metropolis of Los Angeles. The story, replete with backroom deals, broken promises, and outraged locals, serves as a symbol of the greed and ambition that defined water politics in the West. Reisner weaves this narrative with the larger saga of William Mulholland, the ambitious engineer whose name is synonymous with both the success and hubris of L.A.’s water empire. This saga of water, power, and betrayal would later inspire the dark and iconic tale of Chinatown, the Roman Polanski film that captured the moral ambiguities and human cost of Los Angeles’ relentless thirst for growth.

Another cornerstone of the book is the story of the Colorado River, a waterway Reisner calls the most controlled and litigated river on Earth. He charts the creation of the Hoover Dam and the vast network of canals and reservoirs that distribute its water across seven states. The book reveals how over-allocation of the river’s resources, coupled with decades of drought, have pushed it to the brink of collapse—an issue that has only grown more urgent since Cadillac Desert was published.

Reisner also dissects the Central Valley Project and the State Water Project, two gargantuan efforts to turn California into an agricultural Eden. By moving water from Northern California to the arid south, these projects enabled California’s emergence as a global agricultural leader. But Reisner doesn’t shy away from exposing the social and environmental consequences: drained wetlands, salt buildup in soils, and a system that prioritizes agribusiness over the needs of small farmers and urban residents.

What makes Cadillac Desert extraordinary is not just its scope but its style. Reisner’s journalistic rigor is matched by his ability to tell a compelling story. He brings characters like Mulholland and Floyd Dominy, the brash commissioner of the U.S. Bureau of Reclamation (part of the U.S. Department of the Interior), to life with vivid detail. At the same time, his writing is infused with moral urgency, challenging readers to question the sustainability of a society built on unsustainable water use.

The book’s legacy is immense. It galvanized environmentalists and policymakers, inspiring debates about water rights, conservation, and the future of development in the West. Documentaries, academic studies, and even contemporary water management policies owe much to the awareness Cadillac Desert raised. In California, where water battles continue to define politics and development, the book remains as relevant as ever.

As we face a future of intensifying droughts and climate change, Reisner’s insights grow more prescient by the day. California is still grappling with the overuse of groundwater, the challenges of aging infrastructure, and the inequities in water distribution. And while new technologies and policies offer hope, the central question Cadillac Desert poses—how do we balance human ambition with the limits of nature?—remains unanswered.

Tragically, Reisner passed away in 2000 at the age of 51 from cancer, cutting short the life of a writer who had so much more to contribute to our understanding of environmental challenges. His death was a significant loss to the fields of journalism and environmental advocacy, but his legacy endures through his groundbreaking work. Cadillac Desert continues to inspire new generations to confront the urgent questions surrounding water use, conservation, and the future of the planet.

Marc Reisner’s Cadillac Desert is not just a history of water in the West; it is a call to rethink our relationship with one of the planet’s most precious resources. At once an epic tale and an urgent warning, it stands as a monumental testament to the price we pay for bending nature to our will.
