One of the significant areas of climate research right for us in the southwestern United States involves work on modeling the large (spatially and temporally) droughts that are so significant in long term human and ecosystem dynamics. These are the ones that are not just one-year whammies, but linger for decades, like the drought of …
The status of the endangered Rio Grande silvery minnow raises some fascinating transboundary questions. As water moves across state boundaries, who bears responsibility when upstream actions affect an endangered species in a downstream state? The fish, once found from the mountains of northern New Mexico to the Gulf of Mexico, is gone from all but …
In his book Border Oasis, Evan Ward tells the story of the transborder conflict between the United States and Mexico over salinity in the Colorado River. “Unfortunately,” Ward writes, “sometimes when one region solves its salinity problems, it creates new salinity problems for people downriver.” The conflict Ward describes began in 1961 when farmers on …
At a water conference here in Albuquerque last week, one of my water mentors Bill Hume (former editorial page editor at the newspaper, later water advisor to New Mexico Gov. Bill Richardson) made this observation (this is from Bill’s written text, which he kindly shared after the talk and gave permission to me to use): …
Here’s the entire Rio Grande right now, which easily fits through the slot on the east edge of the Angostura diversion dam north of Albuquerque. No water is being diverted. That’s the whole river you see. This is not unusual. The flow measures about 600 cubic feet per second at the San Felipe gauge a …
I was reminded at a talk last night that farmers in the Elephant Butte Irrigation District in southern New Mexico got less than 10 percent of a full irrigation allotment last year. I say that by way of a preface to noting Juliet McKenna’s observation that there’s a 50-50 chance of a formal shortage declaration in …
Filing some pictures this evening, I came across this, taken in the bed of the Rio Grande beneath the Hatch bridge in southern New Mexico on April 29, 2013: This is the sort of thing Jack Schmidt of the Grand Canyon Monitoring and Research Center was talking about at a conference in Boulder last August when he …
Talking about water, and talking about water as a commodity, is not the same as talking about a river. Jack Schmidt, Grand Canyon Monitoring and Research Center, speaking at the Clyde Martz Summer Water Conference, August 2013, University of Colorado
From this morning’s newspaper: The community’s total water use for the year, 32 billion gallons, was the lowest for the metro area since 1983, despite the fact that the population in the utility’s service area has grown 70 percent in the two decades since, according to Katherine Yuhas.
