Ebb and flow of the Colorado River

• The tides on the Colorado River

David Owen talks about the vanishing of the Colorado River. He reports that the river "so much has changed and controlled", that began to resemble the Grand Canal - the force that spins the turbines, irrigates the fields and fills the tanks - each gallon of which belongs to wither states of the American West. Owen follows the riverbed with its origins to Lake Mead, near Las Vegas, where it is clearly seen the depletion of white mineral deposits on the cliffs; from there it goes down to the Gulf of California - the mouth of the Colorado River, where the water is now rarely reach these places. What once was "natural flow" he writes Owen now "is an extensive resource allocation system."
