"Right now the whole world is focusing on our drainage work. Time waits for no one," said Wen. He added multiple plans must be prepared for potential threats, including plans for flotsam disposal and pollution prevention.

Wen said the plans must be adjusted according to real-time lake conditions.

"Currently the 'water bucket' above our people's heads is still there, and so are dangers. We must be prepared to accept new challenges at any moment until all quake lakes are managed."

He encouraged the soldiers to remain strong in the face of danger and fatigue.
