Via Laura Paskus:
The Middle Rio Grande began drying on April 15, and on Monday more than 18 miles were dry south of Albuquerque. We should expect poor conditions to expand in the coming weeks and months — and plan accordingly.
Historically, the Rio Grande experienced snowmelt-driven spring pulses, which spurred fish like the endangered Rio Grande Silvery Minnow to spawn.
But this year, biologists have already had to collect minnows2 from the drying riverbed.
And this:
Last week, when I mentioned river drying at a social event, someone asked me, “Why do you care?” And all I can think is, “How can you not?”
“How can you not?”
Yeah. The minnows are the canaries in the coal mine for us.
It’s coming for the San Pedro in southeastern Arizona.
