Evaporated Water

Smart Water Magazine

“This is a case about evaporated water.” Thus began U.S. Supreme Court Justice Brett Kavanaugh’s opinion for the Court in Texas v. New Mexico, decided on December 14, 2020. Wait a minute!  The Supreme Court is a very busy Court with complicated, serious legal problems to resolve, yet they heard one about something that no longer exists?

Kari Lake’s water-policy mirage – Robert Glennon

Arizona Daily Star
April 22, 2024
Kari Lake’s recent op-ed in the Star set forth her platform for the “most urgent issue” facing Arizona and the South-west: water. I agree, which is why it’s so disappointing that she has so little to offer. Let’s unpack her three main ideas. First, Lake attacks the Biden Administration for policies she thinks will “put...

Colorado River states bought time with a 3-year water conservation deal – now they need to think bigger – Robert Glennon

The Conversation
May 26, 2023
Arizona, California and Nevada have narrowly averted a regional water crisis by agreeing to reduce their use of Colorado River water over the next three years. This deal represents a temporary solution to a long-term crisis. Nonetheless, as a close observer of western water policy, I see it as an important win for the region. Seven western states – Colorado, Wyoming, Utah, New Mexico, Arizona, Nevada and California – and Mexico rely on water from the Colorado River for irrigation for 5.5 million acres and drinking water for 40 million people. Their shares are apportioned under a compact negotiated in 1922. We now know, thanks to tree-ring science, that its framers wildly overestimated how much water the river contained on a reliable basis. And climate change is making things worse.  Read more

The Salton Sea spreads across a remote valley in California’s lower Colorado Desert, 40 miles (65 kilometers) from the Mexican border. For birds migrating along the Pacific coast, it’s an avian Grand Central Station. In midwinter tens of thousands of snow geese, ducks, pelicans, gulls and other species forage on and around the lake. Hundreds of other species nest... Read more »  Read more

Restore the Salton Sea not to its former size but to its role in the ecosystem – Brent M. Haddad and Robert Glennon

LA Times
October 6, 2022
  California’s largest inland body of water is in trouble. Inflows to the Salton Sea have decreased, salinity is growing, the ecosystem is collapsing, and neighboring communities are suffering high rates of respiratory illnesses caused, many believe, by contaminants in dust blowing off the exposed former seabed. It’s not possible to import enough water quickly enough to... Read more »  Read more

Rethinking a finite resource

July 1, 2022
National Hockey League teams in the United States and Canada annually use 300 million gallons of water to operate their arenas. Most facilities use a surprising amount of water. Yet facility managers, much like everyone else, might take water for granted.  Read more
