View Full Version : Colorado Delta gets some water

This is happy news for the day.
A tiny fraction of it's un dammed flow but it's something.


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."


Once written off as dying of thirst and beyond revival, the delta of the Colorado River is slated to get a rejuvenating flood that for scientists offers a unique opportunity: the chance to study how plants, trees, birds, fisheries, and the vast delta ecosystem as a whole respond to an experimental pulse of river water.

This flood is made possible by Minute 319, the add-on to the 1944 treaty between the United States and Mexico that divides the Colorado River between the two neighboring nations.

Signed in late 2012, Minute 319 allows Mexico to store some water in Lake Mead, the giant reservoir behind Hoover Dam, establishes new rules for sharing shortages in times of drought, and commits the two nations to return some flow to the delta as part of a five-year pilot project.

Saw a show on this agreement about a year ago, glad to see it become a reality.

California stole that river... I"ve always that was likely based on racism and disregard for our neighbors to the south
