Happy Birthday to Joni Mitchell, whose song "River" is just so beautiful..
On first listen, you may be lulled into thinking this beautiful ballad is a Christmas song. But listen closer and you’ll hear a woman lamenting that she’s torched the relationship...

In Michelin star restaurants, the chef inspects every plate before it goes out to the floor. And, when he thinks it needs just a tad something more, he adds a little garnish

Today is birthday of @lylelovett.bsky.social who sings about rivers frequently, particularly the Brazos. Here’s his Texas River song about the Pecos, Nueces, Guadalupe, Brazos, Red, Wichita, etc.
“There’s many a river that waters the land” indeed

Photo from almost exactly 16 years ago of my 5-year old daughter in a "Born in USA" cover pose for a Springsteen & rivers essay I'd written.
Today she's home for a few days from her college *senior year* and she's kindly agreed to join me for Springsteen movie "Deliver Me from Nowhere"

With new Springsteen movie, "Deliver Me From Nowhere" out, here's a #WaterYear trip down memory lane. Prob 15 yrs ago I wrote a Springsteen-and-water themed essay & got my kids to pose in front of a river so I could use headline "this river was born to run" (as they imitate imagery of Born in USA)

How vulnerable are riparian trees to drought? Using groundwater and satellite data from a California waterhsed, our new paper found that trees by drying rivers lost up to 5 weeks of growing season, suggesting they’re nearing critical groundwater limits.

Another #WaterYear photo celebrating "Take Me Outside" week. When Luca would catch-and-release fish, Wren worried about the time the fish spent out of water. So, as something of a stopwatch-& gesture of interspecies solidarity-she would put her head in the water for the time a fish was out of water
