LADWP says Owens Lake's 'Owengeti' could suggest new modes for dust control

LADWP's Marty Adams says he calls one parcel of the Owens Dry Lake "the Owensgeti," after the grass and woodland Serengeti.

In one 600-acre patch of the lake, LADWP has begun to mimic nature as an experiment. "We took this area and we releveled it so we put better angles on the dirt, and it worked well," Adams says.

Using bulldozers, LADWP has been trying a new technique called "tillage." Putting a bulldozer at an angle, operators plow in a straight line several feet deep through soil to turn up a layer of clay that can hold salty particles down.

I went out to Owens Lake for a story on dust mitigation with the Los Angeles Department of Water and Power back in April. When I did, Marty Adams and pretty much everyone else from the DWP I encountered were all eager to show me an area on the northeast side of the lake. Adams called it "the Owengeti."

The Serengeti is a grass-woodland in Tanzania and other countries in Africa, legendary for its beauty. (See, e.g., Toto, "Africa.") This 600-acre "Owengeti" is on the far side of the lake, away from Highway 395--unfortunate, says Adams, "because it's far from traffic. The average person sees the salt flats; they don't see the beautiful part on the east side." 

There's plenty of crusty white powder near the "Owengeti," too. It crunches satisfyingly underfoot, though I also was immediately burdened knowing that I contributed to the possibility of the particulate, PM10, flying through the air. "It's like walking on the moon. except i thought the moon would be firmer," Adams said. "It's like a powdered sugar donut." (Though I sort of think it's more like Entemann's crumb cake.)


Eastern California Museum shows us what the eastern Sierra, lower Owens could look like

There's been a lot on the eastern Sierra lately, on this blog. I just wanted to make a quick pitch for the fascinating resource that is the Eastern California Museum. 

I was in this spot the other day-but I couldn't tell till later. If you listened to my story on the radio today you heard Mike Prather talking about a river mosaic - "Wetlands and meadows, closed tree canopies, shrubby understory, cattail bullrush tule-type things." This first picture now lives in the Eastern California Museum; it was taken by Andrew A. Forbes, who had a photography shop in Bishop between 1902-1916. Where these willows and cottonwoods were doing their thing before the 1920s, we've now got tule, tule, tule.

This next one, I snapped. The guy in red is Larry Freilich - Inyo County water department's mitigations projects manager, and I'm facing slightly sideways, while the picture above is facing downstream. But it's pretty close to the same spot.
