New research shows that climate change is causing mountain lakes to rapidly lose ice cover in the winter. That can harm the Mountain West region’s water quality – and native fish.

Eastern Idaho and western Wyoming are hotspots for salmon shares from Bristol Bay, Alaska. Customers are increasingly buying wild sockeye in bulk because they say it tastes better, and they want to support small businesses.

We zoom in on a water restoration project in southwest Wyoming, the headwaters of the Colorado River system that serves about 40 million people downstream. The goal is to restore the surrounding habitat and ultimately hold water on the landscape longer, a problem that's plaguing all of the West. And one way to address that? Humans acting like beavers.

Wildlife agencies are purchasing 3,345 acres of ranchland in the Mountain West that serves as a critical habitat for several species, including a threatened Western fish.

A new study looks into how many fish are in reservoirs across the U.S., and what role these ecosystems could play in conservation and food security.

The Interior Department is spending another $70 million to reopen habitat for native fish in many parts of the U.S., including the Mountain West.

The main thing about Kate Olsen is she’s a fish biologist for the U.S. Forest Service and loves and knows all things fish. Part of her job is managing a fish that is only found in one place in the world: in a 1,000-foot stretch of stream in the Upper Green. The Kendall Warm Springs dace is a tiny fish that’s been listed as endangered for 50 years.

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

A new project on the Bighorn River launched this month with hopes of learning more about the small native fish living in that region.

A new study shows that eating a single serving of freshwater fish in the U.S. can be equal to drinking a month’s worth of water laced with “forever chemicals.”
