Folks on the Colorado River delta “pulse flow” science monitoring team sent around a few pictures yesterday taken by the Sonoran Institute’s Tomás Rivas of the water arriving at the Laguna CILA environmental restoration site. The beauty of this picture for me, beyond the obvious sight of water in a formerly dry delta river channel, is …

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):
