For 40 years, American Rivers has published its annual Most Endangered Rivers list — a powerful statement sparking awareness and action to restore waterways across the country. In this 40th anniversary episode, we talk with Chantel Dominguez from American Rivers to explore this year’s list, river by river, moving through the challenges they face and the tangible solutions for each. We also revisit three rivers from last year’s list to learn about their increasing health and vitality.

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.

This is the 3rd and last episode about the Tijuana River. The Tijuana River is a story of trade, immigration and international borders. This is a river that flows across the US Mexico border and carries pollution and sewage. Our guest is Dr Maria-Elana Giner; she served as commissioner of the International Boundary and Water Commission and upon request of President Trump, she resigned from this position in April of 2025. In this 3rd episode we look for solutions to this epic challenge for the US and Mexico.

Many of our favorite rivers run through public land, land that is owned and managed by the Federal Government, and so therefore owned by the citizens of the United States. There is renewed chatter in Washington DC suggesting that major sales of public lands can create significant revenue for the Federal Government. This episode hosts experts on this topic from the Idaho Outfitters & Guides Association, and the Greater Yellowstone Coalition to learn more about who wants this, why this is being considered, what are the benefits, and how listeners can engage in the process.

Do you ever wonder if bots are being used to acquire river permits during the annual cancellation lotteries each year? So do we. So we built a bot to see if it works to secure permits. And we tried talking with rec dot gov to get their input. Check out this episode for a tour of bots, permits, bureaucracy and access to public rivers.
