Niland, California, 2005
Gerd Ludwig
An irrigation canal reflects dawn-stained skies over Imperial Valley, a fertile farming region just north of Baja California.
The canal brings Colorado River water to the dry Salton Sea watershed, which, with an average of three inches (seven centimeters) of rainfall a year, would otherwise revert to desert. The Imperial Valley’s half million acres (202,343 hectares) of croplands soak up more water than Los Angeles and Las Vegas combined.

Niland,加利福尼亚,2005
Imperial 峡谷里的一条灌溉渠反射出黎明的天空,这是下加利福尼亚北部的一个肥沃的农业区。
渠道将科罗拉多河水带到沙顿海(Salton Sea)流域,这里每年的平均降水量只有7厘米,如果没有引水的话将回转成沙漠。Imperial峡谷202343公顷的农田所吸收的水量超过洛杉机与拉斯维加斯的总合。
