Witness to Water: One Photographer's Mission to Defend the Colorado River

by Pete McBride

For six million years, the Colorado River flowed to the sea.

Sadly, this is no longer the case. Dammed, polluted, and redirected to sustain ever-increasing demand from cities and agriculture, the mighty Colorado now runs dry more than a hundred miles from where it once met the ocean. This disruption of a critical natural resource has caused untold ecological devastation.

Award-winning photographer and filmmaker Pete McBride has documented these alarming changes, undertaking a source-to-sea journey of hundreds of miles to see for himself what had become of his beloved backyard river. Witness to Water chronicles that journey and McBride’s mission to fight for conservation and restoration of the Colorado, as well as a similar source-to-sea journey along the Ganges, and the infamous 750-mile hike through the Grand Canyon that would become the subject of New York Times bestseller A Walk in the Park by Kevin Fedarko.

See the Colorado River as never before, through the eyes of one of its greatest advocates. McBride paints a riveting picture of the water crisis in which we find ourselves and what we risk if we don’t do the work to fix it.

Ok, for the record, this may be called out as "spoiler alert," but people, nonfiction books always are, no surprise endings here. I have had the very good fortune to share space with Pete McBride at 2 different talks sponsored by our little Indy bookstore in our tiny town on the Western slope of Colorado. Pete is our voice. Pete is a friend to our community. Pete is trying like heck to make the rest of the country and world understand that water is life and slipping through our fingers. Pete and I share a love of the river and our home places, and I am grateful that he shares his lived experiences with us. This book isn't flashy. Pete shares his experiences and himself with the raw and concise detail of a journalist while maintaining the heart of an artist. Please read this book and save our mighty Colorado.

An intimate account of both a critically endangered river and the author’s amazing life—and a compelling perspective on what needs to be done to save the river and ourselves. “Fresh water belongs to the mountain peaks, the quiet streams, and the flooding rivers; it belongs to the forests and deltas; it belongs to our wild friends the elk, black bear, mountain lion, osprey, pikeminnow, wood frog, tarantula hawk, and tarantula just as much as it does to our engineered municipal and agricultural needs.”

Read this after reading Kevin Fedarko's "A Walk in the Park." He's not quite as strong a writer as Fedarko (which McBride will admit himself) but he's still a good story teller and the stories about the pulse flow in the delta in Mexico and subsequent trips in the Yampa and Glen Canyon and flights with his father are all well told and thoughtful. Recommend, especially as invaluable first-hand documentation of worsening drought and water mismanagement in the Southwest.

As a freshwater biologist this book hits close to home. It’s sometimes a tough pill to swallow but very eye opening and a story that needs to be told. Without awareness and advocacy, change won’t happen. McBride does a good job tackling multiple layers and issues in a digestible way. While there has been some progress, more is always needed and that starts with knowing what’s actually going on out in the real world. We all live downstream!

Great book. Easy to read- the author tackles a lot but doesn't get caught up trying to tell every detail of a complicated story. This book and Life After Deal Pool have really helped me reshape my ideas about water growing up and living in the west.

Water is Life

Well written book that really captures the importance of our water resources and its impact in our life. Devastating to how much damage has been caused to our resources and how fast global warming is taking effects.

Fedarko's book (from the hike that forms the central trek of this book) was the adventure, this was the context and the soul.

I read A Walk in the Park by Kevin Fedarko, who shared the experience with Pete McBride. That book quickly became a gateway to countless Grand Canyon books and study. I was thrilled when McBride was coming out with this book and bought it right away. I loved hearing about his personal experiences and perspectives with the Grand Canyon, more specifically the Colorado River. I am saddened the more I read and study about the river, many rivers, and dams. I'm sad that so much damage has been done to nature for business and convenience, and to hear how our human influence has shaped and changed the Grand Canyon and many other places permanently. I'm glad to be aware of this issue now and to become more and more of a conservation advocate. I will never forget the image (in my mind) of Pete running aground into sludge as the river just.... dies....

I picked up A Walk in the Park by Kevin Fedarko last fall. And then timing worked out and I finally made my long desired trip to the southwest which included visiting Grand Canyon this spring. So as soon as I saw this book, I ordered and read it right away. I had also just finished The Emerald Mile which is a great companion book because it covers in a lot more depth some of the topics covered in this book.

McBride tells a story that needs to be told, though this book is only one means in which he is doing that. He is a photographer and has spent decades documenting the Colorado and the water crisis that has slowly been building.

The writing is not always graceful, but from what I know of the author, graceful isn’t something he’s ever been called. A lot of the book is short and to the point. But then where are sections, like the Colorado pulse flow where he pulls you in by not just telling the story of the water, but of the people the water touches too.

It’s easy in a prolonged and devastating drought to look at the big problems being created that impact people. Strain on irrigation for farming. Reduced capacity behind dams reducing or cutting off hydropower. Cities struggling to manage water so everyone has it. But where McBride excels in this book is zooming past those issues - while still covering them - to look at the impacts on a local and more human level.
