The world has made it so easy to overlook our natural resources in exchange for revenue. Take a look at dams as an example. According to statistics, we have buried a landmass equal to the size of the state of California in reservoirs behind dams since the start of the 20th century. That is a staggering amount of land lost. In this episode, writer and award-winning filmmaker Steven Hawley sheds light on this alarming information. With his new book, Cracked: The Future of Dams in a Hot, Chaotic World, Steven tells us the impact of dams on the health of our entire ecosystems and, more importantly, what we can do about it. Tune in as he joins Corinna Bellizzi to share more important insights on the state and future of dams and whether it is possible to recover the rivers we lost.About Steven Hawley

The Impact Of Dams On The Health Of Our Entire Ecosystems With Steven Hawley
I've shared my views on how we manage our open spaces and the problem of an over-extracted view of our natural world before on this show. It will come as no surprise to you that we're going to dive deep into another system that we need to work to dismantle with this episode. We are going to talk about dams as we get to know Steven Hawley. Steven is a writer and filmmaker from Hood River, Oregon, my home state. He is the writer and co-producer of an award-winning documentary called Dammed to Extinction and the author of Recovering a Lost River. His new book, Cracked: The Future of Dams in a Hot, Chaotic World, was released on May 2nd, 2023 from Patagonia. Steve was among the first to write about the historic agreement to tear out Edwards Dam on the Kennebec River in Maine. Since then, his work has appeared in High Country News, which is one of my favorite newsletters to subscribe to, OnEarth, The Oregonian, Missoula Independent, and other publications. I'm honored to bring him to you. I can't wait to get started. Steven Hawley, welcome to the show. Thanks, Corinna. I'm happy to be here. I got to spend some time watching Dammed. I picked it up on Venmo for $4.99 and spent an hour being pretty pissed off, to be frank. You start to dive into the world that we have over-harvested for either energy, corporate interest, or what have you. It's maddening. What's happening in the Pacific Northwest is a peculiar situation where you have a government agency that markets and sells power from dams on the Columbia. What your audiences should know about the Columbia is that until those dams were built years ago, the Columbia was one of the world's greatest salmon-producing rivers. It was the world's greatest producer of Chinook salmon anywhere on Earth. We traded that production of marine fecundity. It was a one-of-a-kind marine ecosystem, rivaled nowhere else in the world. We traded that for what has become the most hydroelectrically developed system in the world. As you've said in your introduction, we have reached a point where we need to balance things out and regain some of that semblance of plenitude on the biological side. When I received your book, I started reading from the very first page. You have described so much the problems that we see in this natural world and the importance of our rivers for the health of our entire ecosystems. Something I've talked about before on this show is the impact that salmon migration even has on the health of forests because they evolve together. If the salmon are going further upstream, they're bringing the nutrition that they gained in the ocean to the rivers upstream and then die when they spawn, and their bodies feed the forests. When we impact their ability to get where they need to get, then we're not just impacting the health and tonnage of a salmon population that we can then harvest from the sea. We're affecting the health of the forest. We're affecting the health of the animals that live there and the apex predators, including the bears and anything else that might consume these fishes too. We're creating stagnating waters. We're taking away what could have been fertile and productive land. For what? Here's an interesting statistic that your audiences might appreciate. Since the start of the 20th century, we have buried a landmass equal to the size of the state of California in reservoirs behind dams. This is a staggering amount of land that we have lost. Fortunately, what a large part of my book, Cracked, deals with is the movement to return some of these lands to the oxygen side of the Earth's crust. There are some heartening stories up and down the West Coast. I think of the two dams on the Elwha River West of Seattle, Washington where they took out two dams that were built illegally inside a national park years ago. One of those dams was more than a century old. Scientists have been charting the recovery of this ecosystem, most of which lies protected in the national park. The recovery has been remarkable. This recovery has taken place at a time when the major factor in salmon production or the productivity of oceans has been on the decline. Nonetheless, the Elwha and other rivers where dams have been torn out are giving us an antidote to a less productive ocean. It's not only an aesthetically pleasing thing to have a free-flowing river again. It provides numerous other benefits, including economic ones as well.
Impact Of Dams: We're starving what has been historically one of the richest marine ecosystems on the planet in the name of producing power on a river that produces too much of that electricity, especially this time of year.
There was another story told in that film, which is something we have heard about around the globe when you introduce dams. Indigenous populations are often uprooted. That's exactly what happened in this case. I'm fully endorsing and hoping that people will go out, go to the Vimeo page, rent this film for 48 hours, and watch it as many times as they care to in that time. I was so angry watching the film even though I knew about these things and even though I read a fair amount about the things that happen when you create dams with salmons. I've heard all the stories, "We created a fish ladder so they can swim upstream."
I was happy to see that you addressed that in the film because for those that don't know, I've spent more than a decade in the omega-3 space and fish. I helped to bring to market Kenai wild salmon oil from Alaska. I got to understand the overburdened commercial fishing operations that are out there to secure salmon populations and also the illegal fishing that often takes place impacting these animals. I also visited places along the coast of Alaska where you would see these fish ladders in operation.
There's a great movie from Patagonia called Artifishal that examines that whole world or this idea with the advent of fish ladders and fish hatcheries that we could have our cake and eat it too. We could have dams and hydroelectricity. You could have wild salmon as well. The fact of the matter is you can't. Those hatchery operations are based on an agricultural model of production. Salmon production is not based on that model at all. It's based on diversity and abundance.
For instance, with Chinook, there's a spring run of Chinook and a fall run of Chinook in the Columbia but probably more significant than that, these animals in evolutionary terms are incredible. Remember that every Chinook salmon that spawns in a stream is genetically distinct from its neighbor in the next watershed over. Every wild Chinook salmon has exquisitely genetically adapted to their place.
What you do when you build a dam, cut off access to that place, and try to replace that diversity with a hatchery, is you make it impossible for that key component of a salmon's life cycle or the diversity. It's impossible for that to take place anymore because when they raise farmed fish, which is what they are, they release them all at once. They come back to the hatchery at the same time, and they're simply not adapted to survive in the wild the same way that fish that spawn naturally are.
To my earlier point, they aren't as strong. They can't get upstream even if they had some earlier genetic coding. They're not bringing the nutrition from the sea as far inland, and that has other effects on the ecosystem.
Researchers at the University of Washington found that in forests where salmon are present, tree growth can increase by up to a third. You look at where some of the world's largest trees are up and down the Eastern Pacific coast or the West Coast of North America, the Redwoods, and the old-growth Douglas fir forests in Oregon and Washington. Those are forests that were built by salmon. We don't want to give up on that.
If you were to prioritize the dams that we should look to dismantle first, which might they be?
Since I live in the Pacific Northwest, and I've been working as Citizen Steve on this issue for quite some time, if I could wave a magic wand and get rid of four dams on the lower Snake River, that would be my first choice. However, for your audiences in California and elsewhere that live in the Colorado basin, there are some interesting things happening in Colorado. It looks like with this wet year, there may be something of a reprieve but you're looking at two reservoirs on the Colorado system, Lake Mead and Lake Powell, that are each less than a third full.
With longer summers and increasing rates of evaporation and lower precipitation totals, one of those, the reservoir behind Glen Canyon Dam, which is Lake Powell, has reached a tipping point. That tipping point is there are intakes for the hydroelectric turbines at that dam. Probably the first tipping point is if the level of the reservoir keeps dropping, it's not going to be too many more years before they can't make electricity there anymore but the bigger problem quite honestly is that once the level of the reservoir drops a little bit beyond that, the Colorado River will cease to flow.
In other words, there is no way for the river to get below the penstocks of the hydroelectric turbines. That's where the water spills in and down on a turbine and makes it spin to turn electricity. When the reservoir drops below that level, it has to drop another 90 feet before it gets to the outlet works. The Bureau of Reclamation is hastily trying to figure out ways that they can make a new bypass tunnel or do something to prevent the 30 million people downstream of Glen Canyon Dam who rely on the Colorado River from being impacted because this is a disaster unfolding.
They never anticipated that we would enter this period of dry years and that there wouldn't be a way to release Colorado River water other than through those penstocks. This is a serious dilemma. It's also given an opportunity to people like Gary Wockner who runs Save the Colorado and has been advocating for the removal of Glen Canyon Dam for many years now and other people that are doing this work and saying, "The cheapest solution to your trouble on the Colorado is to get rid of Glen Canyon Dam." I have my wishes about which dams I would like to see come out but our climate chaos is making some of those choices perhaps a little easier to make.
I do know too that there are other dams closer to me, even those that are feeding San Francisco's drinking waters, for example. I believe there's a dam out on Tuolumne or somewhere near there that supplies their water. San Francisco prides itself in having the nicest and tastiest drinking water that's completely pure because of that. What do we do about city populations that rely on these water sources when you're talking about millions of people and the potential removal of dams, which could impact their drinking water supply?
I can think of two things. One is the amount of evaporation that is coming out of reservoirs, especially in hot and dry places or places that by all measures inevitably can become hotter and drier. It doesn't make sense to store drinking water or any water for municipal, industrial, or agricultural use in a reservoir. In the book that I wrote, Cracked, there's a chapter about evaporation. Some of the latest science done by researchers at the University of Colorado have calculated that annually, the standard rate of evaporation, the one that the Bureau of Reclamation used for years, said it's 10% annually. You lose about 10% of the water. That's the cost of doing business.
What these researchers have discovered is it's twice that or more. Inevitably, it's going to grow because we're getting hotter and drier. You look at the amount of water that you're losing in a giant reservoir like the one behind Glen Canyon Dam or even the smaller one that you referenced, which is O'Shaughnessy Dam on the Tuolumne River. It doesn't make sense to store water in that way anymore.
In the case of Hetch Hetchy, there's a gentleman named Spreck Rosekrans who's interviewed in the book. He points out that there's already enough other storage in the Tuolumne system that San Francisco could keep their drinking water. If you took out O'Shaughnessy Dam, it would open up some opportunities for San Francisco to acquire drought year rights that they don't have.
The last thing that I'll mention on that front is a fairly recent development in California to their credit has started to experiment on a large scale with this. Instead of storing water in a reservoir, why not store it underground? There are a couple of experiments going on where water managers are recharging underground aquifers, especially in years like this one. There's going to be a massive surplus of water. This is where all of our groundwater came from originally anyway.
You divert the flow of a river into these underground storage areas, and then it doesn't evaporate. It's available for use in future years. You may not be able to completely recharge some of the underground aquifers that we have depleted but you're not going to lose 20% of that water to the sun either. This is the innovative and creative thinking that is going to be important to get us through what's looking like a very long emergency with the drought that we have.
Impact Of Dams: You divert the flow of a river into these underground storage areas, and then it doesn't evaporate. It's available for use in future years.
My understanding is that our local reservoir, the Lexington Reservoir, may be one of those that is feeding an underground supply. At least I've heard that. I haven't looked into it personally. These are pages 98 and 99 of your book where you compare 2020 to 2022 of what's happening with the Colorado River. The reason this is so critical beyond your mention of this issue with that dam and needing to tunnel it out so the water will be able to move is that the Colorado River supplies much of California farmland.
If you're thinking about the food that we produce and the hay that is grown, it is all coming from the Tuolumne or the Colorado River. Those are the two primaries for what we're seeing here. A lot of Central Valley gets water from the Tuolumne. We have aquifers that are diverting water from the Colorado River and the Tuolumne but ultimately, if we run into an issue, the farmers get hit. Suddenly, they can't produce the hay they normally do. Food costs go way up. This is something that we're already seeing. The price of hay went from roughly $20 for a bale of grass hay to $35.40. It more than doubled. It's gotten ridiculous.
Food security is a huge issue. I don't want to take anything away from that. In the short term, California, because of the powerhouse nature of its agricultural output, has secured the senior most water rights in the Colorado basin. They will be the last to receive cuts but our thinking on issues like this is unfortunately very short-term. It also doesn't answer the question of what happens when the Colorado River stops flowing out of Glen Canyon Dam.
Another huge issue with irrigated agriculture that I don't deal with in this book is the increasing salinity of water as it's used for agriculture. For the Colorado system, this is a huge problem. A lot of water that waters a field drips back into the river, is taken out again, and then waters another field. In the process of flowing through agricultural lands, it becomes more alkaline.
Impact Of Dams: We have become this nation of urban nomads. Staying still in a place long enough not only to get to know it on an intellectual level but to love it requires time.
I already have the answer to one of my next questions but I want to ask it anyway because you never know. You might come up with some other crazy gem that we need to know or a section of the book. If you were to define what your hope for the future is, could you describe that for us?
The final chapter of the book is called What Spirits Might Wear in 2050. It's a vision of those three rivers that are depicted in that final chapter, the Tuolumne, the Colorado, and the Snake all running free. The vision is a little bit flighty, I suppose, but it's also meant to inspire because to get to a place that I'm envisioning at the end of the book in mid-century, you have to start imagining it now.
The reason I wrote yet another book about dams and rivers after I had already written one is that this work is not only urgent, and when it's done, it's done in a way that's powerful, but rivers provide us with the easiest access to finding that spot as we already discussed where you can sit down and see that the world is still a beautiful thing and that we owe it to ourselves, our children, and grandchildren to make it as good as we can possibly make it so that they can do the same thing for their ensuing generations when they're our age. It's ultimately a book about rivers and dams but it's also about hope. I hope it inspires some hope in people.
It inspires people on both sides of the aisle to agree, shake hands, and work toward the preservation of the world's natural beauty. I'm also somewhat of a skeptic. I've heard people make some ridiculous comments like, "If you take the dams out, beavers will create their natural dams."
The flooding argument is probably the biggest mythology about dams. It's that they control floods. There are a few dams that do that thing but even the giant dams that we have here in my neck of the woods provide almost nothing in the way of flood control. They're designed to facilitate navigation and power production. We saw flooding here years ago when the Portland Airport almost flooded because the Columbia was about to overtop its banks. The dams can't control those things. The illusion that you can control those things only makes a disaster worse.
When you straighten the banks with levees along a river, that increases the velocity of the water. When the river finally overtops its banks, you have a bigger problem than what you would have had if you had left it alone. We seem to insist in all of the generations of the past century and a quarter on deploying these grand feats of engineering without thinking too much about the consequences in both the short and long term. It's time to step back from that and recognize that any ecosystem that evolves over hundreds of thousands or even millions of years probably has its inherent wisdom that's worth respecting.
