The North and North Central regions mobilized nearly 280 pumping stations to drain floodwaters.

According to quick statistics from the Department of Irrigation Construction and Management, as of 5 p.m. on October 7, the North and North Central regions had nearly 10,900 hectares of crops flooded. Localities are mobilizing 276 stations/1,352 pumps to drain the water, along with many self-flowing sewer systems.

Specifically, in the Northern region, the total area of ​​rice and crops flooded, damaged, and broken is about 10,476 hectares. The locality with the largest area of ​​flooded crops is Cao Bang, followed by Bac Ninh , Hanoi, Thai Nguyen, and Tuyen Quang. In the North Central region, there are currently about 401 hectares of flooded crops, including 247 hectares of rice and 154 hectares of vegetables, mainly concentrated in Thanh Hoa province. Some other localities are still updating data.

In the North, localities are operating 259 pumping stations with a total of 1,301 pumps. In the North Central region, Thanh Hoa province is operating 17 pumping stations with 51 pumps to drain water. Other localities in the region are mainly operating drainage works using the gravity method.

The Department of Irrigation Construction and Management also said that many large irrigation reservoirs in the North and North Central regions are currently operating to discharge water to ensure safety for the works as well as continue to receive floods when the rain continues.

Specifically, the current water storage in irrigation reservoirs in the North is on average 70 - 100% of the design capacity. The current water storage in reservoirs managed by the Ministry of Agriculture and Environment (3 reservoirs) is on average 91 - 103% of the design capacity. Among them, Cam Son reservoir has a current water level exceeding the pre-flood level of October 2025, at 66.16 m compared to the threshold of 65.5 m and is operating to discharge with Nui Coc reservoir (Thai Nguyen). In addition, large reservoirs directly managed by localities that are operating to discharge include: Yen Lap reservoir (Quang Ninh), Canh Tang reservoir (Phu Tho).

In the North Central region, the capacity of reservoirs is at an average level, with the average capacity of the reservoirs reaching 77 - 99% of the design capacity. There are 3 especially important reservoirs managed by the Ministry of Agriculture and Environment, of which 2 are operating to discharge water: Cua Dat (Thanh Hoa) and Ta Trach (Hue). Other large reservoirs managed by localities are also operating to discharge water: Vuc Mau (Nghe An), Ke Go (Ha Tinh), Da Han (Ha Tinh).

The Department of Irrigation Construction and Management said that according to the report of Lang Son Irrigation Construction Exploitation Company Limited on October 7, the spillway of Dap De reservoir in Thien Tan commune, Lang Son province is experiencing landslides down to the spillway. The Exploitation Management Unit has mobilized excavators to clear the flow through the spillway, ensuring temporary drainage. Currently, the water level of the reservoir is 0.7m from the top of the dam. However, the current rainy weather, the water level of the reservoir continues to rise, and the risk of landslides down to the spillway continues.

Lang Son province has evacuated households at risk of being affected. At the same time, the organization maintains a 24/7 force on duty at the construction site to monitor the water level and landslide situation. If the heavy rain continues, the lake water level will rise and the spillway area will continue to erode, burying the spillway and no longer being able to drain water, it is possible that the auxiliary dam will have to be lowered to ensure the safety of the main dam.

The Department of Irrigation Construction and Management recommends that localities and units operating irrigation works closely monitor weather developments, water levels and the current status of works, paying special attention to vulnerable reservoirs, reservoirs with sluice gates, and densely populated downstream areas when it rains in the reservoir basin. For works under construction, there must be appropriate construction plans to ensure that no incidents occur, and absolutely do not implement items that do not meet the construction progress to overcome floods.

Localities and units shall operate reservoirs in accordance with approved operating procedures; reservoirs with flood discharge gates shall adjust the reservoir water level to ensure safety of the works and not discharge floods abnormally, causing unsafety to downstream areas; at the same time, reasonably store water in reservoirs with low storage capacity; and seriously issue early warnings to downstream residents before reservoirs discharge floods and when there is a risk of an incident.

Localities and units organize 24/7 duty during times of rain and floods; arrange permanent personnel at construction sites at risk of incidents and reservoirs full of water to promptly handle unusual situations according to the "four on-site" motto when there is a risk of construction incidents.
