The Numana Dam fish passage project will open 65 miles of habitat along the Truckee River for the endangered Cui-ui sucker, and for the recently established migration of the threatened Lahontan cutthroat trout from Pyramid Lake. Access to this habitat is essential for the recovery of the species in the wild.(USFWS Pacific Southwest Region / Flickr)

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. The Mountain West News Bureau's Kaleb Roedel reports.
