Home Where We Work Mexico - Colorado River Delta Colorado River Pulse Flow

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."
