Increase flood discharge
On the afternoon of November 24, speaking with Lao Dong, Mr. Ho Dac Chuong - Deputy Director of the Department of Agriculture and Rural Development of Binh Dinh province said that currently, the water level of Dinh Binh lake is at elevation +92.67, with a capacity of more than 235 million m3 (reaching 104% of the design capacity); the water flow to the lake is 1,012 m3/s, the discharge flow is about 752 m3/s.
"The Department is proposing to increase the flood discharge flow to 930m3/s to reduce the water level in Dinh Binh Lake to a safe level. For Dong Mit Lake, the spillway gates are currently being lowered by the operating unit, gradually reducing the discharge flow. It is expected that by tonight, the spillway water will reach the downstream," said Mr. Chuong.
According to Mr. Chuong, before releasing the flood, the Department of Agriculture and Rural Development will send a document requesting Binh Dinh Irrigation Works Exploitation Company Limited to notify localities to grasp information and warn people. From the time the document is issued to the start of the flood discharge, it will take 4 hours, enough time for people in the downstream area to move to a safe location.
According to calculations, with the current river water level and the largest flow through Dinh Binh Lake of 930m3/s, the water level of the Kon River at Binh Nghi is at alarm level 2 (+16.5), at Thanh Hoa is above alarm level 2 (+7.5).
