I feel this morning a bit like a kid watching the NORAD map of Santa on his global travels, as I hit “reload” on the Middle Rio Grande Conservancy District’s new gaging data page. The district opened the diversion gates early this morning at Cochiti Dam, at the head of what we call New Mexico’s …

By John Fleck It is agonizing to watch this, but here we are. With efforts by the Colorado River Basin states to craft an agreement to share the river’s water skidding, brakes screeching, toward a cliff, we appear on the brink of repeating the disastrous mistake the authors of the Colorado River Compact made a …

By Eric Kuhn One of the commentors to our January 19th, 2024, blog post titled “Are We headed for the First Colorado River Compact Tripwire?” – John C. (who, by-the-way runs a very talented water resources engineering firm) raised several finer points to explore further: The first point deals with obligations of each Basin to …

The Middle Rio Grande Conservancy District’s crews will usher the first water into the ditches of New Mexico’s middle valley Feb. 26, district Water Distribution Division Manager Matt Martinez told the district’s board at yesterday afternoon’s meeting.

EDDI is a new experimental tool that offers potential for tracking quickly emerging drought conditions by analyzing the evaporative demand of the atmosphere. It combines how moist things are with how hot and dry …

Folks in Colorado’s San Luis Valley are engaged in a bold experiment in western water management – charging farmers for the water they use.

The U.S. Senate Indian Affairs Committee is holding an important hearing Thursday on S. 2385, a bill to refine the tools needed to help Tribal communities gain access to something that most non-Indian communities in the western United States have long taken for granted: federally subsidized systems to deliver safe, clean drinking water to our …
I’ve been updating the crufty old code I use to generate graphs to help me (and colleagues) think about river flows. This one’s a little busy, so maybe for specific nerd colleagues’ use, and not general consumption? It’s based on a request from a friend who uses these, and asked for a visualization of the …

This Rio Grande crossing, just south of Belen, 30-plus miles downstream from Albuquerque, has changed dramatically since Jack Delano took the picture above in spring 1943. The Bosque I’ve stared at Delano’s picture often, because of the story it tells – a broad open river valley. It’s nothing like that today. I pieced together …
