VIDEO: The Colorado River Reaches the Sea and Brings Life to Its Delta

In the list of conservation success stories of 2014, the return of flow to the once-verdant Colorado Delta ranks high.

The spring pulse flow made possible by Minute 319, the groundbreaking agreement signed in late 2012 by the US and Mexico, brought the Colorado River to the Sea of Cortez for the first time in many years.

Though it returned less than 1 percent of the river’s historic flow to the delta, the surge released at Morelos Dam recharged groundwater, gave a needed drink to trees planted at critical habitat-restoration sites, and generally greened-up the river corridor.

The delta’s signs of come-back provide honest hope that the millions of birds that traverse the Pacific Flyway from Patagonia to Alaska might once again find welcome oases to feed and rest as they cross the vast Sonoran Desert.

But the hard work of the delta’s restoration continues.

Base flows, made possible through the Colorado River Delta Water Trust – a collaboration of Environmental Defense Fund, Pronatura Noroeste and the Sonoran Institute – will supply water to the vegetation that emerged during the pulse, as well as to the native cottonwoods, willows and mesquite trees planted at the restoration sites.

Scientists continue to monitor the benefits of the flow restoration – counting bird varieties and numbers, mapping areas of restored habitats, measuring underground water levels, and more.   This documentation will help make the case for a renewal of the US-Mexico agreement to continue this historic restoration process.

Perhaps more than anything, the sacred reunion of river and sea symbolizes that we humans can choose to repair ecosystems that we might have once written off as gone.

Countries from as far away as Central Asia, grappling with the loss of the Aral Sea and the river flows that had sustained it, are watching this grand experiment with keen eyes for what is possible.

 

Change the Course — a program of National Geographic, the Bonneville Environmental Foundation, and Participant Media – is working with the Colorado River Delta Water Trust to acquire the sustaining flows needed for the delta’s restoration.

    As I was surfing the web, I came across this page about the Colorado River and Minute 319. I/we had no idea that this was happening in 2014. Had it been on the news or somewhere, we would have been there. We were there a many yrs. back when it was a muddy trickle and were saddened by the fact that we even went to see the Colorado that wasn’t a river any more.
    I think this is wonderful and will try to stay informed on what the future holds. I want to be, see, and touch it when it happens again. I have a great love for the Colorado River just because of it’s destiny or more of what it’s destiny was and may once again be to touch the Sea of Cortez.
    We have pretty much erased our water footprint, even though we do not take or contribute to/of the Colorado directly. I can honestly say that my husband and I use approx. no more than 10 gallons of water together on any given day if even that much. I couldn’t believe ppl. were using that much water in the cities, (LA/Las Vegas). I have 2 plants outside and they get water that we have already used, and I count that in with the 10 gallons.
    So I say, THANK YOU Sandra, for all your hard work, and if the Colorado flows again this year, we will be there!!

    • Ruby, thank you for your comments — and your commitment to conservation. Whether or not another pulse flow occurs through the Delta depends on the US and Mexico negotiating another agreement to continue the restoration. Minute 319 called for a 5-year experiment of one pulse flow and supporting base flows. That 5 years is up in late 2017. Hopefully, the restoration will be extended. — Sandra
