Photo taken on Aug. 19, 2018 shows Sanhe gate of Hongze Lake opening its sluices for water discharge in Huai'an, east China's Jiangsu Province. The water level of Hongze Lake continued to rise due to the inflow of Huaihe River and the continuous rainstorm. Flood discharge is increased to further control the water level of Hongze Lake.
