At this time, Dien Thanh drainage, (Dien Chau), workers are on duty operating. Mr. Nguyen Duc Hanh - Director of Dien Chau Irrigation Enterprise said: Dien Thanh drainage culvert mainly drains floods for Dien Chau and Yen Thanh districts. Since 2019, this drainage culvert has been upgraded so it operates smoothly, there is no longer a situation of water hyacinth stuck at the culvert gate.

On the morning of September 27, when the tide was low, the unit opened three sluice gates, each 19 meters wide, with a discharge level of nearly 600 ^m3 /s. At Dien Thuy sluice gate, Dien Ngoc commune, this morning all three sluice gates were opened with a discharge level of over 100 ^m3 /s, and workers were actively salvaging water hyacinth right at the sluice gate.

At Nghi Quang sluice gate (Nghi Loc) since the morning of September 27, water has been discharged at full capacity. Mr. Hoang Van Huong - Station Chief of the Station said: Nghi Quang sluice gate discharges floodwaters for Nghi Loc district, Hung Nguyen, Vinh city and part of Nam Dan district.

The sluice has 13 gates operated by electricity, all of which are fully pulled up with a discharge flow of over 300 ^m3 /s. The current difficulty is that Nghi Quang sluice has many degraded items, such as the gate and valve system being broken, causing operational limitations.

At the same time, Binh Son drainage culvert in Quynh Hung commune and culvert 4B in Quynh Thanh commune, Quynh Luu district are discharging at a rate of 30-35 ^m3 /s, the two above culverts are draining floodwaters for Quynh Thach, Quynh Hong, Quynh Van, and Quynh Ba communes. Currently, the Binh Son culvert area is covered with water hyacinth, making it very difficult to drain the flood. Workers at Binh Son culvert have to take turns to salvage the water hyacinths right at the mouth of this culvert.

A representative of Nghe An Fisheries Department said: Nghe An currently has about 20 large and small drainage systems, such as Nghi Quang three-way sluice, Ben Thuy three-way sluice, Thuong Xa sluice, Nghi Xa sluice, Dien Thanh and Dien Thuy drainage sluices... Currently, only Dien Thanh sluice has been upgraded, the rest are mostly degraded and difficult to operate during the rainy season.

At this time, the Irrigation Department directed irrigation units and workers to stick to the area, be on duty 24/7, discharge water according to the motto "clearing the tide, draining waterlogging"; monitor the water level so that the discharge process does not let salt water intrude./.
