From Bobby Magill, more evidence for my thesis that we’re such profligate water users in the United States that we’ve got lots of room to move as drought and climate change reduce supply: Eventually, TV station weathercasters began reporting the level of the Edwards Aquifer along with the daily weather forecast, forcing residents there to …

As California struggles against the problems posed by its current drought, there has been a great deal of attention paid to the lack of groundwater regulation. Melody Gutierrez has a great example today, from Paso Robles: How scant has the crucial underground water supply become around the San Luis Obispo County city? Sue Luft can …

I’ve often written about the ways in which our rivers in the western United States have become like plumbing (and here, here, and especially here). But one of the most interesting things to me about metaphors is when you push them to too hard. You can learn a lot at the point where the metaphor breaks …

To folks in many parts of the arid western United States, the notion that some California communities don’t meter residential and business water sales seems crazy. It is. This may be, by some measures, a record drought in California. But even without it, Californians have known they have serious water stresses. That it has taken …
If you have any doubt about it, know that the desert begins with the creosote. – Mary Austin, Land of Little Rain
Ben Cook at NASA’s Goddard Institute for Space Studies has a new paper that offers a reminder of why the impact of climate change on our ecosystems and water supplies involves more than “will it rain less”? In some sense this is an old and obvious point, which I link here just to repeat said …

Mark Lubell at U.C. Davis has a fascinating post about the history and politics of drought: [N]early every scientist, commentator, and politician is using drought to make some call for their preferred political change. Regulate groundwater. More storage. Build the twin tunnels. Pass the long-delayed water bond. So given that we’ve been here before (click …

While Lake Mead’s drawdown might be viewed negatively from a perspective of maintaining full-pool water storage, it has re-exposed a vast area of new terrestrial habitat increasingly colonized by native species as invasive species abundance declines through time. That’s from “Plant colonization and soil properties on newly exposed shoreline during drawdown of Lake Mead, Mojave …

tl;dr – It wasn’t the U.S. government “reserving” water rights on behalf of the Indians. It was the Indians keeping the rights they already had. Longer version: After I last took a stab at writing about the “practicably irrigable acreage” standard that sort of underpins U.S. Native American water rights in the west, a member of …
