Watch the water disappear from the northern reaches of Lake Powell in this animation consisting of natural-color images taken by the Landsat series of satellites in spring between 1999 and 2014. The first image, from March of 1999, is labeled. It pauses for an extra second, as does the final image in the series, from May 2014. (Source: NASA Earth Observatory) With California's scary, record-breaking drought capturing so much attention lately, an important bit of news about the dearth of water across a much larger region has gotten short shrift. I'm talking about the Colorado River Basin, which supplies water to 40 million people in seven states — including Californians. Over the long run, the Colorado has been providing less than it once did, even as demand for its water has risen. And this year, as in most years during the past 15, the water situation in the river basin is not looking good.
