From Live Science (Stephanie Pappas):
A release of water down the Colorado River may not reach the sea, as hoped. But it is visible from space.
A new satellite image from Landsat 8 captured a view of the Colorado on April 16. The river is typically dry by the time it gets to this spot in northern Mexico, its flow diverted to feed thirsty farms both in that country and in the United States. The Colorado River has only rarely reached the sea since 1960.
This spring, however, both countries agreed to release more water than usual from the Colorado’s dams in an effort to restore parched ecosystems, especially the Colorado Delta.
