Newly released satellite images of the Colorado River and Lake Mead in Nevada show the impact the historic drought has had on the region in just one year.

The big picture: The nation's largest reservoir by volume is at its lowest level since being filled after the Hoover Dam's completion in the 1930s — prompting the federal government to this week for the first time declare a water shortage for Lake Mead. The Hoover Dam has been operating below its maximum capacity all summer, and it may drop further.
