Authorities have started to fill up the breach of a dike along the Dongting Lake in Huarong county of Hunan province, China Central Television reported.

The water level inside the flooded township and the lake has basically leveled, the report said.

The breach, at the dike in Tuanzhou township, Huarong county, under Hunan's Yueyang city, occurred at around 5:48 pm on Friday.

According to a report by Hunan Daily, the closing efforts started at around 3 pm on Saturday. And it is expected to take 100,000 cubic meters of rocks to close the gap.
