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

On the morning of September 27th, with the tide receding, the unit opened three sluice gates, each 19 meters wide, with a discharge rate of nearly 600 ^m³ /s. At the Dien Thuy sluice gate in Dien Ngoc commune, all three gates were opened this morning with a discharge rate exceeding 100 ^m³ /s, and workers were actively removing water hyacinths right at the gates.

At the Nghi Quang sluice gate (Nghi Loc district), water has been released at full capacity since the morning of September 27th. Mr. Hoang Van Huong, head of the sluice gate station, said: The Nghi Quang sluice gate drains floodwaters for Nghi Loc, Hung Nguyen, Vinh City districts and a part of Nam Dan district.

The sluice gate has 13 electrically operated gates, all of which are raised, with a discharge flow rate exceeding 300 ^m³ /s. The current difficulty is that many components of the Nghi Quang sluice gate are deteriorating, such as the damaged gate valves, which severely restricts operation.

At the same time, the Binh Son drainage sluice in Quynh Hung commune and the 4B drainage sluice in Quynh Thanh commune, Quynh Luu district, are discharging at a rate of 30-35 ^m³ /s. These two sluices drain floodwaters for the communes of Quynh Thach, Quynh Hong, Quynh Van, and Quynh Ba. Currently, the area around the Binh Son sluice is completely covered with water hyacinth, making flood drainage very difficult. Workers at the Binh Son sluice have to take turns removing the water hyacinth right at the sluice gate.

A representative from the Nghe An Fisheries Department stated: Nghe An province currently has nearly 20 drainage systems of varying sizes, such as the Nghi Quang sluice gate, Ben Thuy sluice gate, Thuong Xa sluice gate, Nghi Xa sluice gate, Dien Thanh sluice gate, Dien Thuy sluice gate, etc. Currently, only the Dien Thanh sluice gate has been upgraded, while most others are dilapidated and difficult to operate during the rainy season.

At this time, the Irrigation Sub-Department is directing irrigation units and workers to closely monitor the area, be on duty 24/7, and release water according to the principle of "draining the tide and draining floodwaters"; monitoring water levels to ensure that saltwater intrusion does not occur during the release process.
