Aspen joins water managers using new technologies to map mountain snowpack, predict streamflows

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.

Data viz: explore our interactive dashboards for drought, precipitation and snowpack

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

Does cloud seeding work? Scientists watch ice crystals grow inside clouds to find out

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

Climate change will mean more multiyear snow droughts in the West

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.
