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
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 2, Tijuana River, Source of the Pollution
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.
