“The climate crisis is really a water crisis, and ground zero for that crisis is the Colorado River Basin,” Rice told CNN. “We are being pushed in realtime to live with the river we have, to adapt to a hotter, drier reality in the Colorado River.”
Rivers are a critical source of water, food and energy. These long, flowing bodies of water are vital to many cultures and communities — particularly tribal nations — and are home to a plethora of important species like salmon and trout. They also bolster ecosystems by restoring groundwater and often serve as a buffer against drought.
American Rivers has published the endangered rivers list since the 1980s in collaboration with other conservation groups. It curates the list based on major proposed actions that the public could help influence, the significance of the river to people and ecosystems and the scale of the threat.
“This is a river in crisis because of climate change,” Rice said of the Colorado. “This is not the same river it was two years ago, three years ago or five years ago. We need to learn to live with the river that we have, and we need to implement solutions to allow us to do so.”
Although the Colorado River system is already operating at a deficit, the report says that the climate crisis will likely continue to reduce the river’s flow by 10 to 30% by 2050.
“If the river crashes, it’s a massive economy that’s at stake not only in the Southwest, for cities like Los Angeles, Phoenix, Las Vegas and Denver,” he said. “I would argue that it’s a national economic crisis. This is a national story.”
The Snake River, which flows through parts of Idaho, Oregon and Washington, ranked No. 2 on the endangered list. For years, tribes and local community leaders in the Pacific Northwest — Washington, Idaho, and Oregon — have ramped up efforts to save endangered salmon species from federally built dams. As the planet warms, the river’s water is also heating up, further risking the lives of salmon species that Indigenous people have long relied on..
Scientists have been calling on state governors and other government officials to remove the four federal dams on the lower Snake River, saying that it’s the only strategy that could recover Snake River salmon species.
“Those dams have been the reason why salmon populations are crashing in the Columbia Basin,” Rice said. “So I think that that’s a really important story to tell too, and there’s again a political window of opportunity to actually get this done and remove those dams.”
Additionally, the Mississippi River, which touches nine states from the Minnesota to the Gulf of Mexico, ranked No. 6 on the endangered list due to new contaminants flowing into the river from farm fertilizers and fossil fuel facilities, American Rivers reported.
Over the years, the annual endangered rivers reports have helped remove aging dams, protect rivers and prevent new industrial development and polluting infrastructure from being built in critical river basins.
“The stakes are incredibly high,” Rice said. “This listing is not meant to be a doom and gloom listing, it’s intended to elevate the solutions that we have in the federal funding to implement these solutions. We have the tools to [adapt], we just need the leadership and we need the collaboration to get it done at scale.”
