California, Arizona and Nevada are facing big cuts in water from the Colorado river. Water managers' responses to the federal government's restrictions are now in.

Three western states and the federal government have signed a $200 million deal to keep Lake Mead viable. Millions depend on it for water and electricity. It's at a historic low due to climate change.

Last year Colorado saw the two largest wildfires in it's history, destroying hundreds of homes and 600 square miles of forest. Largely unbothered, though, are beavers, whose wet habitats offer refuge.

The unprecedented declaration of a water shortage in the Colorado River system mostly means less water for Arizona farmers for now, but cutbacks to cities are likely coming soon.
