Where Did All the Rivers Go? (Ep. 41)


Listen Later

Humans are incredibly intelligent creatures, and we have been smart enough to rely on the power of rivers for as long as we’ve been alive on this planet. Over a quarter of people dependent on them, yet in most cities, people may not even see the many miles of river that actively flow beneath their sidewalks. For a hundred fifty years, we’ve been burying streams and rivers under concrete in most American cities–and most of the ones in Western Europe as well. The Executive Director of Seven Canyons Trust, Ronnie Pessetto, is attempting to peel back the layers of concrete that cover many of the creeks in Salt Lake City, Utah. The process is known as “daylighting rivers.” And because Ronnie’s projects are happening right inside a city with a million people, it means the work is as much about civic healing as it is ecological restoration. 

In this episode, Ronnie Pessetto explains why so many rivers got buried in the first place; how to dig them out of their vaults; and how insanely different the water management policies in the West are from those in the Eastern half of the United States. We also get into climate change (like we do almost always, it seems) and how it might reduce the amount of water in Utah, a state that’s already naturally very dry. Daylighting is one optimistic step that can create greater enthusiasm about urban rivers, and ultimately lead to healthier cities. 
"When you uncover rivers, you're not only uncovering water—you're uncovering the stories and the lives and the people that have loved and touched the river."

Ronnie Pessetto is the Executive Director of Seven Canyons Trust, an organization whose goal is to uncover and restore buried or impaired creeks in Salt Lake Valley. Before working at Seven Canyons Trust, Ronnie was a Public Lands Planner for Salt Lake City, where she helped manage various urban parks and trails. 


Seven Canyons Trust has several daylighting projects in different stages, which you can read about here. With joy and care, the work of the organization also includes advocacy, education, and community engagement. This year, the Trust celebrates its 10th birthday. 

The Backstory of the Three Creeks Confluence

Seven Canyons Trust began in a University of Utah class back in 2014, when a small group of students in an Urban Ecology course developed a 100-year plan for daylighting 21 miles of buried creeks in Salt Lake City. One of the centerpieces of that model was the Three Creeks Confluence, an area just Southwest of downtown Salt Lake City where the “three creeks” (Red Butte, Emigration, and Parsleys) meet the Jordan River. (Confluence is the term for where two or more rivers meet). Within just a few years, the students had had turned the project into a formal nonprofit, secured $3 million in funding, and launched a major daylighting effort. You can read the full original plan (the one they turned in to Professor Stephen Goldsmith) here


The Three Creeks Confluence quickly became a national model, earning numerous esteemed planning and landscaping awards, and inspiring daylighting projects around the world. It’s also the perfect example of what Ronnie calls “cultural daylighting” in the episode. Water restoration, she says, goes hand in hand with creating accessible and robust community spaces. The Three Creeks Confluence isn’t just a success story in ecological restoration; it’s a public art site, a music venue, and a thriving community gathering space.


If you find yourself in Salt Lake City, you can visit the Three Creeks Confluence at 1300 South and 900 West. See this webpage

Above, you can see two maps of Salt Lake City. The first shows the Seven Major Creeks of the Salt Lake City Valley. The second highlights where these creeks overlap with recreation in the city – they run through a total of 29 parks! While some sections are still buried, you can see how much of the creeks now flow above ground. 

The Spiral Jetty

If you visit Salt Lake City, in addition to looking at daylit rivers, be sure to make the 90-minute drive out to see Robert Smithson’s famous Spiral Jetty. It’s a large-scale earthwork that extends out into the Great Salt Lake, and it’s a truly incredible piece of art. It was built in the 1970s, but not too long after it was completed, the lake’s water levels rose. For 30 years, Spiral Jetty was underwater and unviewable. Then, in the early 2000s, there were times when the water got shallower, and you could partially see Spiral Jetty again — and other times when you couldn’t. Making a pilgrimage was always a gamble! It’s really only been the past decade that it’s been reliably visible. It now sits fully exposed in a lake bed of salt-encrusted sand. 

On the drive out there, keep your eyes peeled for long-billed curlews and long-eared jackrabbits hanging out in the grasslands.
