Water Lines: Water returns to the Colorado River Delta

Right now, for the first time in many years, the Colorado River is flowing through its historic delta to the sea as a result of an intentional release by water managers. Scenes of jubilation have spread across the Internet as children play in a river they’ve never seen before, and scientists report that bird counts in the corridor are already up.

Meanwhile, combined water storage upstream from the delta in Lakes Mead and Powell have dropped to the lowest they’ve been since Powell filled in the 1960s, as water withdrawals from the river and its tributaries have exceeded new inflows for more than 10 years.

How can this be, that in an era of increasing competition for water, water was found to re-water the Colorado River Delta, and there aren’t riots in the streets? The answer provides a window into the complexities of water management on the river, and the determination of multiple parties to work together to solve its challenges.



The plan to release water to benefit the Colorado River Delta ecosystem was part of a complex “Minute 319” agreement between the United States, Mexico and the seven states that share the Colorado River, as well as several nongovernmental organizations on both sides of the international border. Some of the provisions include allowing Mexico to store water in Lake Mead and infrastructure improvements to Mexican irrigation systems. After a “pulse flow” of several weeks that simulates a moderate flood, minimum base flows will be maintained.

This agreement did not take shape overnight. It took years of study and negotiation by people who came to understand in detail the way the river is managed and the interests of all the parties that rely on this single source of water that brings life to so much otherwise dry land.



Many questions remain about how the natural environment will respond to this release of water, and whether the political environment will allow the experiment to be repeated. But the fact that it is happening at all is a major accomplishment.

If it is possible to find water for the Colorado Delta and simultaneously benefit other water users after a decade of extreme drought, then surely it must be possible to overcome other seemingly irreconcilable differences over water in the West.

This is part of a series of articles coordinated by the Water Center at Colorado Mesa University in cooperation with the Colorado and Gunnison Basin Roundtables to raise awareness about water needs, uses and policies in our region.
