As of Sunday, 4 medium-size reservoirs and 1,388 small reservoirs in Hubei had dropped below the allowable discharge levels for irrigation, the official Xinhua News Agency reported, citing the director of the reservoir management office for the Hubei Provincial Water Resources Department. One-fourth of all small reservoirs had what officials called “dead water” remaining, which could be pumped for use only in an emergency.
The drought adds to concerns over the effect that a gargantuan water-diversion project will have on the central provinces of China. The project, called the South-North Water Diversion, is supposed to move water from the Yangtze and its tributaries north to Beijing along a canal, and to Tianjin along an eastern route.
