Owens Lake: Former toxic dust bowl transformed into environmental success

From The Los Angeles times (Louis Sahagun):

Fearsome gusts of desert wind routinely kicked up swirling clouds of choking dust over Owens Lake on the east side of the Sierra Nevada after 1913, when its treasured snowmelt and spring water was first diverted into the Los Angeles Aqueduct.

It was not until 2001, and under a court order, that the Los Angeles Department of Water and Power began transforming the lake’s grim heritage, flooding portions where toxic, powder-fine dust exceeded federal pollution standards.

In what is now hailed as an astonishing environmental success, nature quickly responded. First to appear on the thin sheen of water tinged bright green, red and orange by algae and bacteria were brine flies. Then came masses of waterfowl and shorebirds that feed on the insects.

On Saturday, Owens Lake was designated a Western Hemisphere Shorebird Reserve Network site of international importance, joining an exclusive group of 104 areas between Alaska and the southern end of South America certified for their outstanding numbers of birds.

Saturday’s designation is part of a growing movement across the nation and around the world that sees wetlands as crucial connections to natural vistas that are receding as the planet heats up and development spreads.

Rob Clay, director of the shorebird reserve network headquartered in Plymouth, Mass., said it is also testament to a Los Angeles dust mitigation project that “demonstrates how human welfare and biodiversity conservation are intrinsically linked.”
