Updated Pulse Flow Map
The U.S. Bureau of Reclamation sent around this updated map this afternoon on the progress of the Colorado River delta pulse flow (apologies for large file size, trying to offer up the highest resolution I can):

Following the flow
While many of us have had to return to more mundane lives, Jennifer Pitt remains in the Colorado River delta, documenting the environmental “pulse flow” as it makes its way toward the ocean. The water’s been slowing as it crosses dry stretches where depth to groundwater is great and dry sand soaks up a big …
Minute 320?
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, …
Colorado “pulse flow”: fighting deeply held perceptions
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 …

“water hoarding” on the U.S. side of the border
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 …

Colorado River pulse flow: managing expectations
More than once last week while I was down in the Colorado River delta, I heard people involved with the historic “pulse flow” talk about one of the problems that comes next: managing expectations. This headline and file art, from Fox Latino, illustrates the problem. “Colorado River Begins Flooding Dried Up Delta,” the headline reads, …

“the most beautiful sight”
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 …
a boy and his river
I consider it a great accomplishment that I spent an entire week in the desert sun of the Colorado River delta without getting sunburned.
A river underground
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 …
Following the Rio Colorado west
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 …
