The River That Made Texas: A Forgotten History of the Trinity

by Scot McFarlane

Today, half of Texas’s expanding population, including the cities of Dallas, Fort Worth, and Houston, depends on the Trinity River, a river that has shaped the state’s politics, economy, and environment for centuries. From the prairies of North Texas to the Gulf of Mexico, the Trinity established Native nations, foiled Spanish and French imperialism, stood at the center of the Texas plantation system, and fueled the growth of the state’s largest cities.

In the first history of this vital river, historian Scot McFarlane illuminates how the Trinity has defined Texas history. Its floods enriched the soil and destroyed crops, its channel served as both a route and barrier to freedom, and its once-polluted waters now sustain a significant portion of the state. McFarlane’s captivating narrative brims with stories of the people who called the Trinity home over the centuries: the Comanche, steamboat pilots, enslaved and freed people, sharecroppers, inmates, and millions of urban residents. The result is a fresh perspective on economic development, slavery, and the environment—revealing the Trinity not as a backdrop to Texas history but as a force that shaped it.

“After reading this expert chronicle of war, slavery, crime, giant alligator gars, and the ageless persistence of human hubris, it’s hard to disagree that Texas history flows through the Trinity River.”—Stephen Harrigan, author of Big Wonderful Thing: A History of Texas

“An unflinching yet clear-eyed and compassionate history of the Trinity River. Scot McFarlane has given voice to the men and women whose lives shaped—and were shaped by—the river, and to the river itself.”—Margie Crisp, author of River of Contrasts: The Texas Colorado

“Surely no river in Texas is as diverse as the Trinity or contributes more to both the economy and biodiversity of Texas, and no author has captured its panoply of gifts to our state like Scot McFarlane.”—Andrew Sansom, coeditor of The Art of Texas State Parks

“In this brilliant study, Scot McFarlane shows how the Trinity River cuts like a knife through the heart of Texas history.”—Karl Jacoby, author of The Strange Career of William Ellis: The Texas Slave Who Became a Mexican Millionaire

“This is one hell of a book. An evocative, at times lyrical place-based history of a landscape haunted by its violent, sometimes horrific past.”—Benjamin Heber Johnson, author of Texas: An American History

“A lively, brilliantly realized, and richly researched account of the stories and memories the Trinity carries.”—Char Miller, author of West Side Rising: How San Antonio’s 1921 Flood Devastated a City and Sparked a Latino Environmental Justice Movement

Reviews

[Sam Hearn]

The River that Made Texas is a fantastic, digestible read with a great story to tell. As the author notes, the history of the river has been woefully undertold, and this book rectifies that with a great balance of history with environmental components, leaving plenty to enjoy for the amateur historian or ecologist. The diversity of the subjects from chapter to chapter meanders well between the distant past and the feeling of floating down river, back to the recent past, chugging along a steamboat up to present day, reflecting on the growth the region is seeing. It makes you want to get outside into the bottomlands, catch a fish, think about what’s been done to the river and what we can do to preserve it for future generations.

I received an advance reader copy of this book.

I got this book as part of the Goodreads giveaway, full disclosure. I was drawn to learning about the river right where I live, in Dallas. As a transplant to Dallas I feel like I need to know about where I live.

I loved the end learning about the people of Texas standing up to big government trying to push what donors want the government to do.

I would recommend this book to anyone wanting to learn about Texas, Texas rivers, Texas history, and people standing up to big government.
