WUHAN, Aug. 31 (Xinhuanet) -- Dongting Lake, China's second largest freshwater
lake, has become clearer, as there was less silk in the lake in the past year
than in previous years.
According to a survey released by the Hydrological Bureau of the Yangtze
River Water Resources Committee recently, there were 38.3 million tons of silt
flowing into the Dongting Lake in 2003. Nearly half of the amount came from the
Yangtze River. The rate ofsilt sediment was 20.5 million tons, accounting for
one fifth of the average rate in previous years.
Chen Songsheng, deputy chief engineer of the Hydrological Bureau of the
Yangtze River Water Resources Committee (YRWRC), attributed the sharp drop in
the amount of silt to the discharge of clear water from the Yangtze River since
the Three Gorges Project began to store water in June last year.
Dongting Lake, next in size to Poyang Lake with a drainage areaof 262,000
sq km, is located in the northern part of Hunan Province, south of the Yangtze.
The lake area has shrunk from 6,000 sq km in 1852 to 2,623 sq km by 1995 as the
result of large-scale land exploitation and silt accumulation.
Chinese experts say the lake will play its role of diverting flood on
Yangtze River again with a silt reduction and conversion of poor farmland back
into lake. Enditem |
