I’ve been joking to my Colorado River management friends about how I keep trying to leave the Salton Sea out of my book. This effort has been such a failure that the Salton Sea now makes multiple appearances in the current draft. All paths to the end of my book’s argument seem to pass through …
Even with a dose of bonus water transferred from the Upper Colorado River Basin’s storage account to the Lower Colorado River Basin’s storage account, Lake Mead is forecast to drop another five feet between now and the end of September, according to the U.S. Bureau of Reclamation’s first forecast of the 2015-16 water year.

The finally elevation at midnight last Wednesday, Sept. …
From his Sept. 30, 1935 speech dedicating what was then called “Boulder Dam,” U.S. Secretary of the Interior Harold Ickes: I venture to hope that this dam, with its great storage of health and wealth and happiness for thousands of people, will stand as a definite opening of a new era with respect to the natural …

Unruly rivers were straightened and channelized , massive levees and dikes were thrown in the way of encroaching water, cheap electricity was …
Southern Nevada Water Authority crews pulled the end cap off of the agency’s new, deeper Lake Mead intake today, and by this weekend they’ll be pumping water from the new system.
