• Bots & River Permits
    Apr 8 2025

    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.

  • Part 2, Tijuana River, Source of the Pollution
    Mar 18 2025

    The Tijuana Rivers courses through the City of Tijuana Mexico where 2 million people live. Several hundred thousand homes in Tijuana are not connected to the city sewage system and this leads to significant pollution of the Tijuana River. And because the city of Tijuana butts right up to the US Mexico border, the path of the river sewage and the responsibility for managing is not always clear. This episode goes into Tijuana to learn more about why the pollution exists, where it comes from and the status of various infrastructure tools that manage the pollution.

  • Part 1 Tijuana River, Binational Flow
    Feb 18 2025

    This episode is on site where a beautiful desert mountain river flows through an estuary and into the Pacific Ocean. Before the Tijuana River meets the ocean, it navigates through a dense urban border region with 5 million people. The outcome is a river that is carrying toxic sewage and pollution to the ocean, closing beaches and creating illness in the river and beach communities. This is the first episode in a series about this beautiful place, the epic pollution, and the incredible people who are engaged in the work to clean up this river and ocean.

  • Part 2, Hurricane Helene in Appalachia, River Rescue
    Feb 4 2025
    River runners became paramount for river rescue in many parts of Appalachia when Hurricane Helene inflated the rivers to record levels. People were stranded in buildings, bridges blew out, and houses were swept downriver. This live episode at the America Outdoors Conference hosts 3 river runners who immediately engaged in the rescue of people stranded by the floods, and, the rescue of the rivers from their own floods. They tell the stories of their work beginning at daybreak on day 1 of Hurricane Helene.

  • Part 1, Hurricane Helene in Appalachia, The Science
    Jan 21 2025

    In September of 2024 when Hurricane Helene arrived in the mountains of North Carolina, Tennessee and South Carolina, it landed where the ground and rivers were already saturated and swollen with rain. The result was “the storm of record” taking out thousands of bridges, sending thousands of landslides down the mountains and taking human life. This episode hosts the National Weather Service and the Lower Mississippi River Forecast Center to explore the storm and the river reaction, and then Dr Phillip Prince goes deep in describing landslides and debris flows and their impact.

  • Part 2, Dr Len Necefer, 2025
    Jan 7 2025

    Dr Len Necefer opens up 2025 for The River Radius. Len is the mind and perspective I wanted to welcome me and you both into this 6th season of The River Radius. We talk through the relationship of rivers and elections, of books for this year, the work and impact of Secretary of the Interior Deb Haaland, and other river and life layers. Len is the founder of Natives Outdoors, the Sonoran Avalanche Center, runs rivers, is articulate and intelligently humorous. This is the 2nd episode with Dr Len Necefer and both are some of my favorites.

  • Part 1, Dr Len Necefer, Living in the Soup
    Dec 30 2024

    To move from 2024 into 2025, we have one guest in two episodes for you. Our guest is Dr Len Necefer. This is the first episode. We talk through life wrapped in intellect and self facing humor, 6th grade reading levels, native art and the modern retail market, an upriver bike ride, and river runs at the northern most reaches of the North American continent. Len is the “star” of his Outside TV show where he is riding his bike up the Colorado River from Mexico to Colorado. He is the founder of Natives Outdoors. He served the Obama Administration in the Dept of Energy. And Len is part of the founding crew of the Sonoran Avalanche Center. Len and I sat on top of a small mountain, on a park bench looking down on the deep desert river and ski town of Tucson, Arizona on a Sunday morning in the end of November to laugh and learn, and talk life and rivers.

  • Declaration of Rights for the Biobio River in Chile
    Dec 26 2024

    Do rivers have rights? Should they have a set of rights that guide how they are used? In September of this year, 2024, the Biobio River in Chile was assigned a Declaration of Rights. This non binding document allows for work to be done towards making the Declaration influential and even binding at a later date. We speak with International Rivers and Malen Lebu in Chile to understand this more.
