China's quake-devastated Gyegu Township of Yushu Tibetan Autonomous Prefecture began the reconstruction Wednesday of its flood control projects to prepare for the upcoming flood season, said local authorities.

The action came after part of the 12-km embankments in Gyegu was damaged by the 7.1-magnitude earthquake on April 14, according to a spokesman with the Water Resources Department of Qinghai Province.

With a total investment of about 42.5 million yuan (6.15 million U.S.dollars), the reconstruction would take six months, said the spokesman.

The government would also build 5,486 meters of new embankments, said the spokesman.

It would also dredge the Batang and Zhaxike rivers, he said.
