What does El Niño mean for the Colorado River Basin?
What does the growing El Niño oceanic pattern mean for the Colorado River Basin? Best to just shrug, and say the statistics are too small to say much of anything conclusive. In the nine El Niño years since the 1960s, three have been wet, three have been in the middle, and three have been dry. Here’s a …

Thus far, an excellent New Mexico monsoon
Those unfamiliar with the volcanoes on Albuquerque’s west side will have to take me at my word when I assert that they are not normally this green:
Risks of 2016 Colorado River shortage declaration pretty much gone, risks of 2017 also shrinking
The Bureau of Reclamation’s latest 24-month study, out this afternoon (pdf), shows continued improvement on the Colorado River system’s big reservoirs as a result of the hella rainy spring and summer, and therefore a continued reduction in the risk of a Lower Basin shortage declaration. The number to watch is a Lake Mead elevation of …
An Albuquerque rainstorm for the record books
That thunderstorm that woke most of us up early this morning (lightning flashes through our skylight at 1:30 a.m.) was one for the record books. At the National Weather Service’s airport gauge (the “official” Albuquerque gauge), 2.24 inches (5.7 cm).

Halfway through June, another million acre feet on the Colorado River
The June mid-month forecast from the Colorado Basin River Forecast Center is up a million acre feet from June 1. Total April-July inflow into Lake Powell is now projected to be 6 million acre feet, up from 5 million acre feet forecast on June 1. That’s still below average, just 84 percent of the mean. …

This is fascinating:
“Miracle May” leaves Colorado River reservoirs in much better shape than when the month started
A month that Eric Kuhn of the Colorado River Water Conservation District in western Colorado called a “miracle May” has left the Colorado River’s two largest reservoirs in much better shape than we might have expected given the glum projections of doomsayers like me. Precipitation across the Colorado River Basin has been well above average, …
