ABQJournal video edition of the weekend post-fire flood flow explainer, with the remarkable Kerry Jones video of the torrent in Cochiti Canyon: (Thanks to Troy Simpson, Richard Pipes and Kerry Jones)
One of my new tricks when looking at western water problems is to pose the question: “What is the failure mode?” It’s clear that on many scales, both temporal and geographic, we’ve got supply-demand imbalances. It’s easy to point that out and call the system unsustainable, to point out that we’re headed for a crash. …
The results of a couple of trips north last week into the flood zone in the canyons below the watersheds burned by the Las Conchas fire (sub/ad req): In Cochiti Canyon, a New Mexico Environment Department team estimated the Aug. 21 flow that caused the first round of damage at Dixon’s at 12,000 cubic feet …

If you’ve driven the stretch of Interstate 40 across northern Arizona between Gallup and Holbrook, you’ve perhaps seen the signs for a place called Goodwater. If you’ve not, trust me – there’s not much good water around those parts. The story of human settlement in the region is the story of the struggle for good …
Jay Lund and colleagues have modeled a range of possible impacts of climate change on flood flows in California. From a nice summary on the UC Davis California WaterBlog: Warming generally worsened flood inflows into reservoirs. Even with less precipitation, warmer conditions often increased flood inflows to reservoirs. When more precipitation fell as rain, rather …
A river is not just in one place. It extends in time up and down its watershed. Last night, Daniel Porter at the Albuquerque National Weather Service office sent out an alert of possible flooding on Peralta Canyon, which enters the Rio Grande about 40 miles north of Albuquerque. Its watershed was burned in the …

New Mexico’s in the midst of a tense and interesting discussion about the Rio Grande silvery minnow, the Endangered Species Act and managing the Rio Grande. I’ve got a post up over at the work blog going meta on the underlying issues – why I think ESA discussions have become our proxy discussions for big …

John Bass today argues for clarity in our use of language when talking about a water conveyance around the Sacramento-San Joaquin Delta: Could I ask that Dan Bacher and those he quotes use the term “canal” when referring to a canal to take water around the Delta, the term “tunnel” for the other option under …

Over at the Lane Center, a look at what the extra water on the Colorado River means: While Colorado Basin water users had survived 11 years of drought without suffering shortages, simply by draining their two big reservoirs, US Bureau of Reclamation calculations raised the clear possibility that by next year, the first ever shortage …
