Colorado River Pulse Flow Event
Starting on March 23, 2014, the United States and Mexico will release some 105,000 acre-feet of water into the delta below Morelos Dam, which straddles the Colorado River on the U.S.-Mexico border.
Although this ‘pulse flow’ represents less than one percent of the annual average flow of the Colorado River, it will be an historic event for the region, stemming from the groundbreaking, multi-faceted Colorado River agreement negotiated between the U.S. and Mexico known as Minute 319. The event will help with efforts by the U.S. and Mexico to reestablish riparian habitat, providing benefits to wildlife species and communities along the Colorado River in both countries and in the Colorado River Delta region in Mexico. The pulse flow event also creates an unprecedented model for water-sharing agreements elsewhere in the Colorado River basin and beyond.
"The pulse flow is a vital part of our ongoing restoration efforts," said Francisco Zamora Arroyo, director of the Colorado River Delta Legacy Program at Sonoran Institute. "We know that relatively small amounts of water can make a big difference in the health of the delta region."

Dramatic photographs capture the mighty Colorado River kissing the sea for the first time in 50-years off the coast of Mexico after dams were intentionally unleashed
(September 10, 2014) - For the first time in half a century the Colorado River kissed the Sea of Cortez in Mexico this May, providing photographer Pete McBridge a glimpse into the past of an American continent untouched by man's meddling.
The river, which flows high up in the Rocky Mountains of the United States, winds its way 1,400 miles south. Over the past hundred or so years its journey has been dammed and changed more than a dozen times to feed and irrigate cities across the West. Read the DAILY MAIL article.
A River Running
(September 4, 2014) - Pulse flow feeds more then dry Colorado River Delta.
If Boulder Creek dried up, and the bridge on Broadway spanned nothing but an empty stretch of sand, and it stayed that way for decades, eventually people would forget what it had meant to see a stream running there. To have place to put feet in the water, a green bank on which to sit, a surge to seed the cottonwoods and willows downstream, an exhale from the mountains when the snow unpacks itself into melt water each spring.

This video describes how history is being made in the Colorado River Delta this month when the U.S. and Mexican governments release some 105,000 acre-feet of additional water into the river as part of the binational agreement known as Minute 319. The unprecedented "pulse flow" of water marks a major milestone in the longstanding efforts to bring life and water back into the depleted Delta.
Delta - Pulse Flow Experts:
The Sonoran Institute has several staff members who are experts on the Delta restoration effort, and on the pulse event. These members of our team are available for interviews, and more detailed information about what's happening in the Delta.
