Melting away in a hot drought

The snowpack that 40 million people rely on for water was supposed to provide a bounty this year. Instead, much of it melted away fast and early — part of a long-term trend associated with climate change.

Scientists use simple cameras to answer complex questions about forests and the snowpack

“Snowtography” captures how the snowpack can vary dramatically across short distances

Once a rich desert river, the Gila struggles to keep flowing

Population growth, agricultural withdrawals and climate change have badly diminished the river and threaten its future.

Spring runoff forecast looks better than last two years

Colorado’s predictions for spring runoff are looking better than the past two years, but streamflows are still expected to be below normal.

Critical April snowpack above average, but potential for dry spring causes concern

While snowpack and reservoirs are strong, forecasts for streamflows, which build as melting snow reaches streams, are expected to be below normal across southwestern and southeastern parts of the state.

La Niña likely to continue, intensifying drought, wildfires; snowpack hits 91% of average

Colorado's drought may continue into the fall, bringing a third year of below-average snowpack and streamflows and high wildfire danger.

On average, atmospheric rivers have about twice the regular flow of the Amazon River.

Drought and decreased snowpack have left Colorado reservoirs below average capacity levels.

In a first-of-its-kind project, scientists will trace snow from where it arrives in the atmosphere, to where it melts into the ground.
