  • Outstanding Podcast

    Just started listening after this podcast was recommended by Zach at NW Rafting. I listened to two podcasts and they were both outstanding. I look forward to more episodes. Great work.

  • Getting way too political

    You guys have done a great job, but lately you’ve gotten away to political. I just listened to an episode that instead of being about the river was about politics. I think I’ll be taking a break from a while till you get away from the politics

  • Great podcast — and not just for river folk!

    I will struggle to write this review and not be over the top effusive in my praise for this podcast. This is the best researched, written, and produced podcast about rivers……period. Sam Carter, the host, is a delight to listen to and his background in local NPR shines through. Sam is a great interviewer and gets people talking at a depth you might not expect. Imagine Terry Gross in a splash jacket.

    Sam wonderfully avoids the “two chuckleheads talking” model all too common in small, topic specif... more

Talking Points

Recent interactions between the hosts and their guests.

Live with The Returning Rapids Project, at the America Outdoors Conference
Q: What is a returning rapid, and when did you first notice it?
A returning rapid is where a riverbed that had been flooded by a dam exposes sediment again as the reservoir drops, allowing the river to carve back and re-create a rapid; the team first noticed this change in the early 2010s as Lake Powell declined and sediment dynamics became visible.
3 Women 300 Miles, River Boarding the Grand Canyon
Q: What do you do when you need to eddy out and you can't?
It's about problem-solving and surrounding yourself with really good teammates.
Ben Stookesberry, Exploratory Kayaking & Ecuador
Q: What is the relationship between activism and kayaking for you?
He sees it as important for kayakers to support local communities and advocate for river protection.
Ben Stookesberry, Exploratory Kayaking & Ecuador
Q: When did the kayak game change?
It changed when he first saw the impact of illegal gold mining on the Jatunyacu River in Ecuador.
Albania's Vjosa River
Q: Tell us, we're here to talk about the Vjosa River. Would you tell us about the Vjosa? If I'm saying it right, where it starts, how long it is, how much water is in there, how much volume?
The Vjosa is a river located in northwest Greece and southern Albania, roughly 270 kilometers long, where the first 80 kilometers runs through Greek territory, and then it enters into southern Albania.
