Man-made lake plan simply for water supply stability: WRA

Man-made lake plan simply for water supply stability: WRA

Taipei, April 5 (CNA) Taiwan's first large man-made lake project is simply aimed at stabilizing the water supply in southern Taiwan, a water resources official said Monday.
Joses Y. H. Wu, deputy director of the Water Resources Agency (WRA) under the Ministry of Economic Affairs (MOEA), made the remark to rebut claims by some environmental groups that the Jiyang Lake project is aimed at benefiting gravel industry operators.
When a project to dig five man-made lakes in an area straddling Kaohsiung and Pingtung counties was proposed five years ago, Wu said, the 72 million cubic meters of gravel expected to be extracted were considered an important resource for southern Taiwan, because the region faced a shortage of gravel for the construction industry.
However, Wu said, the picture has changed greatly after Typhoon Morakot wreaked havoc in southern Taiwan last August. Since then, more than 15 million cubic meters of gravel have been dredged from the Cishan and Laonong rivers, which flow into the Gaoping River, to date.
As a result, southern Taiwan has stopped importing gravel from China and will likely not have to do so over the next three to five years.
Out of environmental concerns, however, the MOEA has decided to cut the number of man-made lakes to be dug in the region from five to only two, Wu said.
Noting that the Jiyang man-made lake project has been approved by the MOEA, the Council for Economic Planning and Development and the Environmental Protection Administration, Wu said the project is simply aimed at helping stabilize the water supply in southern Taiwan, which has often been troubled by water shortages.
The proposed lakes will be able to conserve river water during the rainy season and restrain land subsidence by reducing the extraction of groundwater. During the dry season, it will serve as a supplementary source of water, Wu said.
According to the WRA's plan, the project will get under way in 2011, with a budget of NT$17 billion. The new lakes will be able to store 20 million cubic meters of water.
