The unexpected history of Las Vegas and Hoover Dam

Folks in Nevada today are celebrating the 80th anniversary of Hoover Dam’s sort-of-semi-official power production. Hoover Dam is such a dominant feature on the history of the west in the 20th century that it’s fun to contemplate what people thought about it before it happened. One of my fascinating side trips when I was researching …

Do US native communities’ water rights extend to groundwater?

In the 1908 case, Winters v. United States, the court ruled Indian tribes are entitled to sufficient water supplies for their reservations.

The message from the Colorado Delta pulse flow: a little water can go a long way

There’s an important point I try to make when I’m out in public talking about the 2014 Colorado River Delta environmental pulse flow: the amount of water used and the size of the landscape that got wet, compared to the once-vast delta, is tiny. I get excited about the pulse flow, when water managers on …

Climate change in the Colorado River Basin

Discussions about climate change and water supply in the western United States risk getting bogged down in pursuit of uncertainties. Those uncertainties are real, but there’s a bunch that we already know, and it’s sufficient to help us form policy responses, according to a new summary paper from the Colorado River Research Group: Assuming the …

Greenhouse gases and southwest “megadrought”

Scientists have dubbed decades-long periods of aridity in southwestern North America “megadroughts“. We’ve had them in the past, and research has long pointed toward an increasing risk of them as the climate warms. New research published last week by Cornell’s Toby Ault and colleagues has generated a wave of scary headlines – A Mega-Drought Is Coming to …
