Dams

Idaho rivers were once home to one of the country’s largest salmon runs. Today, however, those same salmon are headed towards extinction.

While debate continues over whether or not to remove the four lower Snake River dams to help fish, like endangered salmon, in other places, dams are already coming down for a variety of reasons.

The next big phase of the Klamath River Dam removal started this week. It's the largest dam removal in U.S. history and is expected to last through 2024.

Nationwide, millions of barriers - like dams - are plugging up rivers and streams. And that makes it hard for fish to move freely and lay their eggs. Now, the federal government is spending more than $200 million to reopen spawning grounds for fish. That includes an effort to recover an endangered species that's sacred to the Pyramid Lake Paiute Tribe in Nevada.

Officials want to raise Anderson Ranch Dam to provide more water storage to the Boise Basin.

A new interactive story map shows many of the nation’s dams are aging. That poses a threat to downstream communities, including dozens in the Mountain West.

As drought and steady demand shrink the Colorado River and Lake Powell, Glen Canyon Dam faces an existential threat. It's a rare example of the Southwest's water crisis made visible.

Just over a year after President Joe Biden signed the Bipartisan Infrastructure Act into law, a flood of money is already being put to work to restore aquatic ecosystems in the Mountain West.

Looking down at a pool filled with Klamath River salmon swimming back to their spawning grounds, Karuk Tribal Councilor Aaron “Troy” Hockaday says he can’t wait to see what the future holds for them.
