In High Country News, Matt Jenkins on the Colorado River delta environmental “pulse flow”, which grew out of “Minute 319”, an addendum to the U.S.-Mexico water treaty: Over the past two decades, the Delta’s advocates have argued their case with perseverance, and a lot of good numbers. By monitoring the effect of the pulse flow, …
Folks working on the current Colorado River “pulse flow” must fight against the deeply held perception that the river in Mexico’s Colorado River delta is “dead.” Blame Phillip Fradkin, whose 1981 book “River No More” is one of those touchstones in the regional literature that dominates public understanding, even if it isn’t quite right. Writing …

Ricardo Castillo celebrates the Colorado River “pulse flow” and reminds of us the transboundary tensions that preceded it. He sounds pissed: U.S. Americans proudly boast about the beauty of the Grand Canyon and the might of the Colorado River as “great American treasures.” Over the past 50 years, however, both the U.S. federal government and …

Packing up this morning to head home after a week watching the environmental pulse flow on the Colorado River into Mexico. Ran across this in one of my notebooks, from Bob Snow, an attorney in the U.S. Interior Solicitor’s Office who has been working on this since the ’90s and helped negotiated the international agreement …
I consider it a great accomplishment that I spent an entire week in the desert sun of the Colorado River delta without getting sunburned.
You’ve seen lots of pretty pictures of the Colorado River flowing anew into its delta, right? But one of the most interesting things going on is the movement of water out of sight, beneath the ground (see “hydrology at the end of a river” for some background). I had a chance this morning to visit …
I took a break today from the excitement of following a newly rejuvenated Colorado River south, across the border into Mexico, where it rarely flows, and followed “the river” west instead. Forty-nine river miles upstream from the “Southern International Boundary” – essentially the bridge at San Luis Rio Colorado – a structure known as Imperial …
SAN LUIS RIO COLORADO – Morelos Dam, the last dam on the Colorado, normally diverts the river’s entire flow west, into the Canal Reforma, for farms in the Mexicali valley. In Spanish, it’s called “Presa Morelos,” where “presa” means “dam.” But Francisco Rosas, a Mexicali farmer, told me that it has a second meaning – …
