The collapse of a section of the Kakhovka hydroelectric dam has released a torrent that is only beginning to subside, leaving downstream nature reserves underwater and vast mudflats emerging from an emptying reservoir.

The reservoir’s 19 cubic kilometers of water—more than is currently stored behind the major dams of the Colorado River—began to spill through a breach in the dam.
