After the dike breach, an embankment considered the second line of defense was threatened on Monday.

团洲垸的决堤代表洞庭湖的“第二道防线”受到威胁。

Efforts to plug the dike breach started on Saturday afternoon, after the water level in the lake went down.

6日下午， 待洞庭湖水位水位下降后，各工作组开始封堵堤坝决口。

The dike breach followed 17 days of heavy rainfall in Hunan, the longest continuous period of heavy rain since 1961.

堤坝决口前，湖南面临了17天暴雨，这是自1961年以来最长的连续暴雨。

Following the dike breach, a large volume of water from Dongting Lake rushed into the Tuanzhou dike region, flooding 47.6 square kilometers of the region's total area of 55 sq km.

堤坝决堤导致洞庭湖的大量湖水涌入团洲垸，淹没了该地区的47.6平方公里，其总面积约为55平方千米。
