From National Geographic (Sandra Postel):

Now in its 14th day, the historic pulse flow coursing through the Colorado River Delta toward the sea is under the careful watch of dozens of scientists who fan out across the landscape to measure and track its vital signs – from flow rates and salinity levels to seed dispersal by native cottonwoods and willows.

The goal is to learn as much as possible from this unique experiment in large-scale ecosystem restoration so that future pulse flows – designed to mimic the spring flood that naturally occurred before large dams and diversions were built – will deliver as many benefits to river health, habitat creation and local communities as possible.

“This is a once in a career kind of thing,” said Karl Flessa, professor of geosciences at the University of Arizona in Tucson and Co-Chief Scientist of the monitoring team for Minute 319, the binational agreement signed in late 2012 that established the terms of the pulse flow.

“Scientists all around the world are watching.”
