The Bicycle of Theseus and the Paradox of Identity

In the fall of 2003, I bought a new bicycle. I wore spandex and those practical (albeit a bit silly) cyclist’s shirts with pockets on the back for snacks. In the years that followed, I rode that bicycle a great deal. While my data are imprecise (my crazy data nerd spreadsheet has all the miles, …

Colorado River water reduction rules: not quite voluntary, not quite mandatory – “vandatory”!

After Friday’s blog post and some intemperate tweeting about whether the Colorado River Drought Contingency plan cuts about to go into effect were voluntary or mandatory, a friend involved in the negotiations explained that they actually came up with a word for this: “vandatory”. The idea was that everything they all agreed to in DCP …

A decent (not great, but decent) water year on the Colorado was not enough to stave off mandatory cuts

Walking across the University of New Mexico campus yesterday afternoon on my way to orientation for our incoming UNM Water Resources Program students, at precisely 3:10 pm MDT, a friend sent me a historic text message: “1089.4”. Translated from the native language of the Colorado River Water Nerd, “1089.4” means “The surface of Lake Mead …

(Technically it’s my co-instructor …

The Salton Sea: “treat it as a real place that impacts real people’s lives”

Imperial Valley resident (and Imperial Irrigation District board member) Jim Hanks: The Salton Sea is a real place to me and I have always seen it as a lake, because that’s what it is. I also see it as hydrologically, geographically and morally connected to the Colorado River, and I appreciate the effort to place …

The biggest year since 1995 on New Mexico’s Middle Rio Grande

Thanks to continued high flows, this is now the wettest year on New Mexico’s Middle Rio Grande since 1995. My measurement point is the San Felipe gauge on the Rio Grande in north-central New Mexico. The measure is total flow to date this year, compared to total flows at this point in all previous years …

Resilience and my little Rio Grande sandbar island

Since early spring, I’ve taken my early morning bike ride through downtown Albuquerque to the old Route 66 crossing of the Rio Grande. Every time, I’ve stopped to check out this little sandbar island, anchored by a tenacious community of willows. I started watching closely after I saw a pair of geese, frantic as the …
