Soyang River Dam opened the water gate in three years. Soyang River Dam is the last bastion of flood control in the Han River. 

As the heavy rains continued for the fifth day, the Soyang River Dam exceeded the flood limit limit, and the Soyang River branch of the Korea Water Resources Corporation opened five floodgates from 3 pm today (5th) and releases 3,000 tons per second.

Based on the current 3,000 ton discharge, it is expected that it will take about 16 hours for the water discharged from the Soyang River Dam to reach the Han River.
