Praise for Robert Glennon

“If you want to scare yourself silly, read Water Follies …. You’ll learn how America is irrigating itself to death … while sucking its groundwater aquifers dry.” Margaret Atwood, in the Toronto Globe & Mail.

“The wells of the American dream stand a good chance of running dry; and to read Glennon’s necessary book is to know that without water there will be no wine, no roses, nothing over Dorothy’s rainbow except a pillar of salt.” Lewis H. Lapham, former editor of Harper’s Magazine and founder and editor of Lapham’s Quarterly.


“In Unquenchable, the examples of what uses the most water … were shocking.” Jon Stewart, on The Daily Show.

” … a lively account of hydrology ….” Bill McKibben, in the New York Review of Books.

“Robert Glennon has the heart of an environmentalist and the head of an economist. He also has a very good sense of humor – or maybe the absurd – which is on fine display in his survey of the nation’s use and abuse of its vast but imperiled water resources…. Unquenchable is a significant event in the literature of water management.” Tracy Mehan III, in The Environmental Forum.

“Robert Glennon connects the dots between our water woes and climate change, energy, growth, the environment, and agriculture. He makes a compelling case that we need to rethink how we use this prized resource and provides a number of thought-provoking solutions.” then-Senator Mark Udall, Colorado.

[Water Follies] is a book as rich in detail as it is devastating in its argument.” Douglas Jehl, in Scientific American.

” … an array of informative stories that should contribute to shaking us out of what Glennon calls ‘the unlimited human capacity to ignore reality.'” The Washington Post.

Kari Lake’s water-policy mirage – Robert Glennon

Arizona Daily Star

Colorado River states bought time with a 3-year water conservation deal – now they need to think bigger – Robert Glennon

The Conversation
May 26, 2023

Arizona, California and Nevada have narrowly averted a regional water crisis by agreeing to reduce their use of Colorado River water over the next three years. This deal represents a temporary solution to a long-term crisis. Nonetheless, as a close observer of western water policy, I see it as an important win for the region.
Seven western states – Colorado, Wyoming, Utah, New Mexico, Arizona, Nevada and California – and Mexico rely on water from the Colorado River for irrigation for 5.5 million acres and drinking water for 40 million people. Their shares are apportioned under a compact negotiated in 1922. We now know, thanks to tree-ring science, that its framers wildly overestimated how much water the river contained on a reliable basis. And climate change is making things worse.
