Floating Albuquerque’s Rio Grande: notes on “naturalness”

The Rio Grande is up through Albuquerque right now, swollen with spring snowmelt. But not for long. We may already have hit the runoff peak at a bit above 3,000 cubic feet per second in late April, and a friend who’s been cheerfully nagging me to float it with them talked me into locking down …

Rapid snowmelt on New Mexico’s Rio Grande

A recent rapid warmup has brought high flows to the Rio Grande through New Mexico. But with a modest snowpack sitting in the mountains to the north, that means we should expect the early rise to be followed by an early drop. Members of the Inkstain Rio Grande Rapid Response Team (IRGRRT) were busy over …

The loss of El Vado: some followup

A couple of followup notes related to last week’s post about the news on El Vado Dam on the Rio Chama, crucial to water management on New Mexico’s Rio Grande, thanks to my many alert and thoughtful Inkstain readers….

The Loss of El Vado Dam

The Bureau of Reclamation’s announcement at Monday’s meeting of the Middle Rio Grande Conservancy District that it is halting work on El Vado Dam repairs raises hugely consequential questions about water management in New Mexico’s Middle Rio Grande Valley. The short explanation for the halt is that the current approach to repairing the 1930s-era dam …

Otowi flow, without the log scale: 21st century peaks are ~half what they were in 1980-2000

Alert Inkstain reader John correctly questions the impression left by the log scale I used last time ’round in my graph of flow at Otowi: [W]hile I appreciate the usefulness of logarithmic scales for being able to discern patterns at the low end of the flow range, it does somewhat hide the magnitude of the …

Happy Rio Grande Spring Runoff!

It is telling that I got excited when I noticed inflow into New Mexico’s Middle Rio Grande Valley approaching “normal”, which I now define as the median of 21st century flow. Our climate-altered world, y’all. A note on the evolution of the graph: I’ve added the “max” and “min” lines back. I dropped them because …

New Mexico’s Rio Grande reservoirs: Running on Empty

Inspired by Jack Schmidt’s monthly “how much water is in Colorado River storage” posts (see here for last month’s), I’ve been playing with a similar tool to help me think about the status of our reservoirs on the Rio Grande system here in New Mexico. The graph above helps me with two important intuitions about …

New Mexico’s Rio Grande, at the U.S. Supreme Court

The U.S. Supreme Court will hear oral arguments tomorrow (Wed. March 20, 2024) about the fate of ongoing litigation between Texas and New Mexico about how to share the waters of the Rio Grande. The two states (Colorado is technically a party two, but this is really Texas v. New Mexico) have what they think …
