(This grew out of a comment from Tom on the blog and a subsequent email exchange.) By Tom McCann As we struggle with a long term management plan for water use …
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 latest US Bureau of Reclamation “24-month study” – the monthly update to projected reservoir storage on the Colorado River – shows the bottom dropping out of Lake Powell inflows after a starkly dry April.

Felicia Marcus on the West’s water problems: The problem with vast water negotiations like the Colorado River Compact, said Marcus, the Stanford water policy expert, is that every entity, from governments down to people watering their lawns, come to expect the current amount of available water — even if that availability is an outlier or …
