Yamaguchi Prefecture has decided to "emergency release" to the Kotogawa River downstream from 3:30 pm because the water level of the Kotogawa Dam in Ube City is rising due to heavy rain.
Since there is a risk that the Koto River will rise, we are calling on the residents of the Koto area of Ube City, which has already been instructed to evacuate, to evacuate.
When "emergency release" starts, there is a risk of flooding downstream
"Emergency discharge" is a discharge performed at a dam that has a function to suppress the rise of water in the river. It is called a disaster prevention operation during an abnormal flood, and the water that flows in when the amount of water flowing in due to heavy rain approaches a state where it cannot be stored. It is an urgent operation that discharges the same amount of water as.
Although the water stored in the dam is not flushed at once, there is a risk of flooding downstream when the "emergency discharge" begins, so people near the river should evacuate.
