Let's examine one by one whether there is a place where the rain damage has increased due to human error, and whether there are places that have been sufficiently prevented. First of all, the torrential downpour was particularly damaging to the residents in the lower river area. It has been pointed out that the flood damage could be reduced even if the amount of dam discharge was well controlled, but it turned out that the Yongdam Dam in Jinan, Jeollabuk-do, did not comply with the operating guidelines.

First, this is reporter Lee Yong-sik.

12:00 noon on the 8th. One hour after the emergency evacuation order was issued to Geumsan residents of Chungcheongnam-do, Yongdam Dam greatly increases the amount of discharge to three times that of the dawn of the day.

2,900 tons of water per second poured out at once, swallowing up Geumsan's houses and agricultural land in just two hours.

[Jungho Jang/Jaemin Geumsan: All this was a wall. There was a long window, but the water

flows in from the Yongdam Dam .] The water flowing down here from the Yongdam Dam reaches Geumsan, Chungcheongnam-do, Yeongdong, and Okcheon in North Chungcheong Province, and has a direct impact on the upper water level of the Geum River. Is going crazy.

Before the flood, we looked at the discharge of Yongdam Dam.

At 12 o'clock on the 7th, the day before, the amount of inflow per second was about 2,000 tons, but the amount of discharge was only about 300 tons, which is 15%, and at 3:40 pm, when the amount of inflow increased, the amount of discharge was further reduced to about 10%.

It violated the dam operating guidelines that the water level of the dam should be kept below the flood limit by controlling the amount of discharge during the flood season.

Suddenly, a large amount of water was poured out and he did not even provide proper guidance.

An emergency letter stating that the amount of discharge will be doubled was sent to the residents at the scheduled release time.


Water Resources Corporation is only blamed on the weather.

[Lee Han-gu/Director of Water Resources Corporation: I have to say that we had to increase the amount of discharge compared to some unexpected rainfall, and that we considered the safety of the dam.] A

flood is visible in front of you. There is.
