When Irving Berlin penned “White Christmas” more than six decades ago, he did not have Albuquerque in mind. According to the National Weather Service, the chances of actually seeing falling flakes here on Christmas are about one in thirty. But that does not stop Rin Tara and John Fleck from hoping, scanning the long range weather forecasts as they write those last holiday cards and record their last podcast of 2025.

The old Western cliché that whiskey’s for drinking while water is for fighting over has always been problematic. Frequently attributed to Mark Twain, it seems that Twain never said it. And research by the Utton Center’s Stephanie Russo Baca shows that sharing water – ensuring that no one goes dry when the water runs low – is a viable approach to New Mexico water management.

In practice, New Mexico’s water law has always had an uneasy relationship with the “doctrine of prior appropriation,” the legal principle that newcomers should have their water cut off in times of shortage to ensure that those who came first can get a full supply. Russo Baca’s work shows how formalizing water shortage-sharing agreements can serve as a viable alternative, keeping irrigation ditches flowing that might otherwise go dry.

In this episode of Water Matters, Rin Tara and John Fleck talk with Russo Baca about how shortage sharing agreements can work, about their cultural heritage in New Mexico’s deep history of water sharing, and about how the state’s laws are adapting in the 21st century to make these new arrangements possible.

This week, Rin and John talk about flows on the Rio Grande, planning for a new federal river management project south of Socorro, groundwater contamination questions, and the future of federal clean water regulation.

Rio Grande

With the irrigation season over and the Rio Grande’s riparian vegetation shutting down for the winter, river flows are up through Albuquerque. But the biggest reason for the high flows is the annual Rio Grande Compact accounting exercise, as water stored in Abiquiu reservoir for the six Middle Rio Grande Pueblos, but not needed, is moved down to Elephant Butte Reservoir.

To track the flows, the USGS measurement gage at Central Avenue is Rin and John’s go-to information source: Rio Grande at Albuquerque, NM - USGS-08330000

And to get the best report on current river conditions, we recommend Anne Marken’s monthly presentations to the Middle Rio Grande Conservancy District Board of Directors. The audio recordings, including Anne’s slides, are here, and once the meeting minutes are posted, you’ll get a great written summary.
