Over the past year, the question of how to account for evaporation and system losses in the Lower Colorado River Basin has become a hot political and policy topic. With the recent Lower Basin water use reduction scheme, we seem to have set the question aside for now. But it’s not going away. My Science …
By Eric Kuhn and John Fleck With the arrival of all of the commissioners and their key advisors, the Commission got back together on Saturday morning. The purpose of this meeting had been agreed to back in early April. Each commissioner would be given the opportunity to suggest the form of a compact. Nevada’s James …
By Eric Kuhn and John Fleck On Saturday, April 1st, 1922, at 9:00 AM in Denver’s iconic Brown Palace Hotel, Chairman Herbert Hoover opened the 9th meeting of the Colorado River Commission. The official meeting lasted only 30 minutes. The commission took only one action of consequence. It asked its members to submit to Executive …
Eric Kuhn: One hundred years ago, we had some flexibility because the river was not very well-used. Today, not a drop of the Colorado River reaches the Gulf of California, so we don’t have that luxury. The way I look at it is: we legally allocated water based on an assumption that this river system …

Our friends at the University of Arizona Press have kindly printed a bunch of new copies of our book Science Be Dammed, this time in paperback so it’s cheaper! Eric and I did a fun Q&A with Abby Mogollon at the press to accompany this second launch: Q: Why did you embark on this project? …
Preparing for climate change on the Colorado River is hard. But we will make it harder, and narrow the scope of our options for dealing with it, if we don’t incorporate realistic flow reduction scenarios in our planning efforts. That’s the thrust of an editorial Brad Udall and I have in this week’s issue of …

The conventional simplification of the Colorado River Compact’s water allocation scheme is that it set aside 7.5 million acre feet of water use for the “exclusive beneficial consumptive use” of the states of the Lower Basin – Nevada, Arizona, and California. In the 21st century, the official accounting shows the Lower Basin states using an …
When USGS reports a century ago suggested there wasn’t enough water to meet the allocations of the Colorado River Compact, the politicians just kinda pretended they weren’t there. I wasn’t done this blatantly: Hours after President Trump assailed guidelines issued by the Centers for Disease Control and Prevention for reopening schools, Vice President Mike Pence, …
By Eric Kuhn As Utah pushes forward with its proposed Lake Powell Pipeline – an attempt move over 80,000 acre feet per year of its Upper Colorado River Basin allocation to communities in the Lower Basin – it is worth revisiting one of the critical legal milestones in the evolution of what we have come …
