If I wanted to make mischief, I’d write a blog post pointing out that Lake Mead ended May at a historic low right after release of 105,392 acre feet of water for a historic environmental flow through the Colorado River Delta. I’d calculate how much higher Lake Mead would be if that 105,392 acre feet …

Poking in the garden this morning, I’d never have guessed without actual rain gauge data that we just finished a wet month. It’s really dry out there. But drought is a funny thing, eh? 0.55 inches (1.4 cm) of rain at our house in May was the first above-average month since November. My total …

Another example of reasons to be optimistic about our water future? With just half its normal precip last winter, Israel is in what might properly be characterized as a meteorological drought this year. But not to worry, according to this AP report: Tenne said the country has managed to close its water gap through a …
Five years ago, Lissa and I stopped to talk to a ranger on the Petroglyph Point Trail at Mesa Verde. We’d been admiring the turkey vultures soaring above the canyon, and the ranger clued us in. If you like turkey vultures, she told us, go to the Spruce Tree House overlook at dusk tonight and …
Unless tropical depression Amanda does something miraculous, and quickly, Lake Mead will end May at its lowest level for this point in the year since Elwood Mead and his buddies filled the reservoir in the 1930s, 20 feet in surface elevation below last year at this time. The “tropical storm Amanda” thing was a joke. …

I suppose if you work this image from yesterday’s Landsat pass over the Colorado River Delta hard enough, you could find a path of wet connection between river and sea: Image courtesy USGS Earth Explorer
We’re not running out of water in the West. What we’re running out of is cheap water in the West. – Jeff Mount
As Southern California looks at its next water supply steps, one of the top items on its agenda is cleaning up groundwater contamination. It’s cheaper than building more storage. So says MWD’s Jeff Kightlinger: I think you’re going to see the next wave of investments over the next decades in Southern California focused around issues …

Another reason for optimism about our ability to solve our water messes: [I]n most regions, the water needed to feed one person decreased even if diets became richer, because of the increase in water use efficiency in food production during the past half-century. Global Changes and Drivers of the Water Footprint of Food Consumption: A …
