Snowpack

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.

In studying what led to this historic avalanche cycle, snow scientists are identifying some elements — such as warmer temperatures, wetter air and snow, and more-intense storms — that are consistent with a warming climate.

Cloud seeding disperses dust-sized silver iodide particles into clouds so that ice crystals can form on those particles and fall to the ground as snow.

Pitkin County is warming, the number of frost-free days is increasing and snowpack is declining—all of which have myriad impacts on life in the Aspen area.

As a changing climate renders streamflow predictions less accurate, water managers are turning to new technologies for a clearer picture of what’s happening in their basin’s snowpack.

These maps and visualizations let you interact with vital data on our water supply.

Cloud seeding occurs in more than 50 countries, but we still don’t know whether it works.

Ifclimate change continues relatively unabated, consecutive years with snow drought conditions will become much more common, with impacts on cities, agriculture, forests, wildlife and winter sports.
