LAS VEGAS—Water will once again flow in an old Colorado River channel in Mexico that's been sucked dry by farms and cities.

The Las Vegas Review-Journal reports ( the gates of Morelos Dam a mile south of the border will open March 23 to release a man-made flood expected to last eight weeks.

It's part of an experiment that will be closely watched by a team of Mexican and American researchers.

The so-called "pulse flow event" mimics the floods that happened each spring before the Colorado River was dammed up and its waters stored in reservoirs such as Lake Mead.

It's meant to spur the growth of plants and trees in the now-dry river delta.

The project was authorized by a 2012 amendment to a treaty between the U.S. and Mexico.
