Dr. Adriana Martinez grew up in Eagle Pass, Texas, swimming and playing in the Rio Grande as a part of daily life. 10 years after getting her Ph.D and teaching university classes in fluvial geomorphology, her Texas hometown and home river became the iconic center of the modern immigration debate and the setting for the controversial river buoy border fence.  In this episode she tells us about the research she is conducting to learn how the buoy fence in the Rio Grande is impacting this river, and about growing up riverside to an international border.

Tim Palmer has spent much of his life floating down, writing about, and photographing America’s rivers. With 34 books and scores of awards to his name (including the first-ever lifetime achievement award presented by American Rivers), he’s one of river conservation's most seasoned voices. In this episode, guest host Clark Tate joins Tim to talk about a recent run down the newly dam-free Klamath, his lifelong bond with Pennsylvania’s Youghiogheny River, the origins of America's flood management system, the benefits of giving rivers the room they need to run when the waters inevitably rise, and how increasingly severe floods both reveal our vulnerabilities and offer opportunities.

This September brings the one year anniversary of Hurricane Helene and the powerful flooding that pounded Southern Appalachia. Incredible work has been to remove the bridges and cars and houses and trees that filled up the rivers. And more work continues today and for the next 18 months to clean up the remaining smaller trash. In this episode we learn about these details and how some communities did not flood because dams were removed prior to Helene, and how more dams are being removed post Helene.  Our guests are Hartwell Carson and Andy Hill from Mountain True in North Carolina.

After incredible collaboration and momentum at the Snake River amongst several tribes and two states to create a legitimate pathway for the 4 Lower Snake River Dams to be breached and therefore allow the anadromous Salmon, Steelhead and Lamprey of the basin to avoid extinction, the collaboration has been cancelled by the current presidential administration.  Why?  What comes next?  Our guests are full of passion and wisdom for this story: Kayeloni Scott from the Columbia Snake River Campaign and Libby Tobey from the Grand Salmon Project.

Every year, we ask one big question: What is a River? This year, the currents brought us to Dr. Robert Macfarlane—writer & professor—and his newly released book, Is A River Alive?, Dr Macfarlane joined us to explore that very question. From the chalk streams from his home in England to rivers across three continents, Macfarlane pursues his answers. In this episode, we move through his global journey, his new water literacy, and why he calls himself a teacher first.

In this episode, we dive into About Damn Time, Dana Romanoff’s powerful film that follows Cindell “Dellie” Dale and a crew of boatwomen as they navigate handcrafted wooden dories down the Colorado River through the Grand Canyon. They spent 17 days and 277 miles running the river and filming the story. Their journey becomes a vivid exploration of women reshaping a river culture long dominated by men. We ask: How did they work together to tell this story? What wisdom flows from these women to the next generation of dory guides? And why is the dory the most poetic boat ever built to run through the Grand Canyon?

Every July, more than 500 paddlers push off from Kansas City down 340 miles of massive Missouri River current, paddling day and night across the state in one of the world’s longest nonstop river races. This is the MR 340, an event of endurance, suffering and transformation. From solo racers chasing records to 10-person canoes grinding it out over four brutal days, every paddler faces the same river. In this episode, we sit down with Kate Mansker, a racer from the very first MR 340 in 2006 who still holds course records, and Steve Schnarr, the race director who steers the chaos behind the scenes. Together, they chart the evolution of the race, the legends it’s created, and what it takes to avoid the Reaper.

Katie Veteto is a river guide with quiet calculated confidence and a sharp eye for water. Within a few years she was navigating one of the most difficult crafts on the river—the massive sweep boat. NRS's new film Driving Sweep, directed by River Radius Contributing Host Greg Cairns, follows her journey of learning, doubt, and determination as she takes on a role historically dominated by men. Through her story, the film offers a powerful reflection on resilience, mentorship, and making space in wild places.

GUESTS

Katie Veteto
Katie Veteto was born in Southern Utah, raised in the Missoula Valley, and now spends her time in Missoula, MT and Salmon, ID. She grew up seeing the rivers of the West through the joyful lens of community and recreation and continues to guide on rivers in Montana and Idaho. Katie is an elementary school teacher. During Katies time off, you’ll find her romping in the woods with her dog Tuck, swing dancing, knitting hats, writing, or bumping around on a bike. In the Summer you’ll find her somewhere on the Middle Fork of the Salmon.
