Nature Responds to Colorado River Delta Pulse Flow

The Colorado River has been flowing in its delta for more than three weeks, thanks to a cooperative effort by the United States and Mexico to deliver a “pulse flow” of water. The pulse flow is meant to mimic – albeit at a small scale – the spring floods that historically inundated the delta and…

Landscapes Transform With the Arrival of the Colorado River

It’s a rare event to see a river literally form before your eyes. But each day that we ventured out to find the leading edge of the Colorado River as it advanced through its delta during this historic “pulse flow,” we were treated to exactly that phenomenon: a dry, sandy channel that hasn’t seen water…

Update From Colorado River Delta: A Community Gets its River Back

For more than two weeks, the Colorado River has been flowing in its delta, through more than 30 miles (48 kilometers) of recently bone-dry river channel choked with desert scrub.  The flow is all too brief, lasting only eight weeks in all.  The United States and Mexico are demonstrating how a “pulse flow” of water…

Monitoring the Pulse of the Colorado River

Now in its 14th day, the historic pulse flow coursing through the Colorado River Delta toward the sea is under the careful watch of dozens of scientists who fan out across the landscape to measure and track its vital signs – from flow rates and salinity levels to seed dispersal by native cottonwoods and willows.…

Will the Colorado River Delta Pulse Flow Make it to the Sea?

One of the big unknowns of the pulse flow of water currently working its way down the channel of the Colorado River in its delta is whether that water will reach the sea.  The mouth of the Colorado River drained historically into the Upper Gulf of California (Sea of Cortez), a unique body of water…

Chasing the Historic “Pulse Flow” Through the Colorado River Delta

For one week now, the Colorado River has been flowing into its delta.  It’s the first ever deliberate release of water here to benefit the environment. That the river is flowing again in its delta is somewhat astounding, all the more remarkable because it’s happening as the result of cooperation between the United States and…

A Colorado Delta Community Reconnects with its River

On Tuesday afternoon, March 25, 2014, word got out that the river was coming. Kids, parents, dogs and teenagers began gathering at the bridge in San Luis Rio Colorado, a border town of about 160,000 people. Young people had never seen the river that gives this town its name flow beneath the bridge. They waited. …

Witnesses to History at Morelos Dam on the Colorado River

A dozen dignitaries faced a crowd of more than two hundred gathered yesterday at Morelos Dam in the Mexican city of Los Algodones, Baja California, to proclaim the release of a “pulse flow” of Colorado River water to its dry delta a momentous occasion for both the river and binational relations. (See “Historic Pulse Flow…

Water Flows Into Colorado River Delta in Historic First

Sunday March 23, 2014, at a little after 8 am, the gates at Morelos Dam on the Mexico-Arizona border were opened for the first time in history for the purpose of allowing the Colorado River to flow downstream into its delta to water the plants and animals that live there.  A crowd of more than…

This World Water Day, Something Big to Celebrate

On Monday, March 24, I leave on a trip to witness an event I never thought I’d see:  the Colorado River flowing through its delta toward the sea. Except in years of unusually high precipitation in its watershed, the Colorado hasn’t coursed through its delta for most of the last half century. Its entire flow…

Report Shows Unanimous Support for Colorado River Conservation

“Mapping the River Ahead,” a new report by Carpe Diem West, provides an insightful discussion of solutions for the Colorado River Basin.  The authors conducted anonymous interviews with more than 30 “water leaders” (disclosure, I was among them) representing a broad range of sectors and locations.  The anonymous process was a useful strategy to get…

Well, not really, but they do make some good points in this funny video calling for restoration of the embattled, and thirsty, Colorado River Basin. The celebrities are working to support Raise the River, a campaign building…
