加利·达菲在圣保罗报道。

The Sau Reservoir is already at less than 10% capacity.

绍水库的蓄水量已经不足10%。

Back at the Sau Reservoir, authorities are actually draining most of the remaining water to prevent this precious and ever scarcer resource from getting contaminated by the sludge at the bottom of this once mighty lake.

再让目光回到绍水库，当局实际上正在抽干大部分剩余的水，以防止这一珍贵而日益稀少的资源受到这个曾经巨大的湖泊底部污泥的污染。
