A new study shows climate change is melting glaciers and permafrost in the Mountain West. Researchers say this can trigger the production of toxic mercury in mountain wetlands, posing risks to water supplies and wildlife.

For decades, hydrologists believed most spring snowmelt rapidly enters rivers and streams. But a new study from the University of Utah shows that most of it spends years as groundwater before it spills into reservoirs – new research that could help western water managers and farmers better plan each year.

A new study reveals snow in the Rocky Mountains is contaminated with mercury and other metals, and that pollution has historic causes.

Winter is coming. But how much snow will it bring? Federal forecasters recently released their outlook for the season, and projections for the Mountain West are all over the map.

The federal government is spending nearly $5 million to improve drought monitoring and forecasts in the West to help states, communities and farmers better plan and prepare for droughts.

A new study shows just how much climate change is shrinking water supplies for Western farmers. But its authors also have some ideas of what they could do to adapt.

More than 100 years ago, a professor in the Mountain West invented a tool and technique to measure the amount of water in a snowpack — a discovery that still lives on to this day.

New research shows less snow is falling in many parts of the U.S., including the Mountain West, a region that relies heavily on snow.

The wet season got off to a weak start in the Mountain West, but federal officials say recent winter storms have helped strengthen some snowpacks.

A new study shows human-caused climate change is shrinking snowpacks around the world, raising concerns for regions where communities and industries rely on snow.
