Snowpack

Technology to study the impact of dust on downwind mountain ecosystems in Colorado and Utah will likely be installed in the Rockies this fall.

A judge has granted a water conservancy district in northwest Colorado a water right for a new dam-and-reservoir project that top state engineers had opposed.

Front Range water providers hope to expand a program that uses a new technology they say will revolutionize water management in Colorado.

Due to budget shortfalls, Vail Resorts has pulled this winter’s funding for its cloud seeding program, potentially reducing the amount of water flowing down the Colorado River this spring.

What started as a promising water year for Colorado with above-average snowpack ended Sept. 30 with the entire state in some level of drought.

The snowpack is crucial to the West’s water supply, ecosystems and economy. But climate change threatens to make the region’s snowpack thinner and less reliable. We talk to a leading snowpack researcher about how scientists are analyzing the past, present and future of the West’s snow.

The city of Aspen is hoping some grant money can help it collect more data on snow and streams in the high country so it can better predict and plan for droughts.

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.

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.

Although snowpack in the mountains near Aspen is hovering above normal for this time of year, streamflows in the Roaring Fork River are predicted to be just 85% of normal for April.
