WANZHOU, China - When this city decided to dam a tributary to the mighty Yangtze River, the city fathers searched for a suitable name for the beautiful artificial lake they said would form. They settled on Goddess Lake. They planned a tree-lined park along its shores, a tranquil respite from city life. Little boats would ply its waters. Six months after Goddess Lake began filling up, it's become a cesspool filled with pig blood, dead fish, raw sewage, dye and runoff from tanneries.
EDIT
Similar stories of environmental degradation are unfolding along the Yangtze upriver from the Three Gorges Dam. As the huge dam and smaller dams along the river's tributaries block the water, the flushing and self-cleaning action of the Yangtze River basin has slowed. Reservoirs are becoming sewers, filled with trash and smelly water. Local officials refuse to shut down polluting factories, fearful that unemployment will rise. Edicts from Beijing on controlling industrial waste go unheeded.
EDIT
Earlier this month, the State Environmental Protection Administration declared that pollution treatment projects along the Yangtze were "not as smooth as planned," the China Daily newspaper said. Local officials declined to close 206 of 304 small and medium-sized factories, including paper mills and distilleries, which the central government targeted as major polluters, a report by the agency said. In addition, 242 large factories, including steel and chemical plants, were told to improve their pollution control facilities. Of these, 227 haven't completed the work, it said. Industrial plants up the Zhuxi River include a pig slaughterhouse, a fruit juice cannery, textile industries and a dye factory, residents said. Numerous pipes pump sludge into the reservoir, which in turn funnels into the Yangtze through a flood-relief sluice.
EDIT
About a quarter of the 207 tributaries that flow into the Yangtze River are so seriously polluted that the water is unfit for irrigation, local press reports say. The Yangtze's water quality has also deteriorated. State officials say it's at grade three under a Chinese rating system, which means it's of poor quality but usable for various purposes. However, the state system doesn't include a count of coliform bacteria, a sign of raw sewage, which would drop the grade further. Some 30,000 ships and vessels operating in the Three Gorges Reservoir dump an estimated 7 million tons of excrement into the Yangtze every year. Moreover, cities keep dumping raw sewage into the river basin."
