Northern Vietnam operates 94 stations to drain water.

According to the Department of Irrigation Construction Management, Ministry of Agriculture and Environment, as of 5 PM on July 21st, localities in Northern Vietnam were operating 94 stations with 342 machines to drain water.

Specifically, Phu Tho has 1 station/6 devices, Bac Nam Ha has 6 stations/44 devices, Hanoi has 4 stations/6 devices, Hung Yen has 32 stations/101 devices, Hai Phong has 7 stations/32 devices, Bac Ninh has 30 stations/115 devices, Ninh Binh has 14 stations/38 devices) and 62 sluices (Ninh Binh has 51 sluices, Hanoi has 3 sluices, and Hung Yen has 8 sluices).

Currently, Phu Tho province has 11.8 hectares of rice, crops, and fruit trees that have been flooded, damaged, or destroyed. Other localities are continuing to update their figures.

Due to the impact of Typhoon No. 3, heavy rain is causing a risk of flooding and damage in low-lying areas of Ninh Binh, Hanoi, Hung Yen , Phu Tho provinces and cities, etc.

Regarding the situation of irrigation reservoirs, the current water levels in irrigation reservoirs in the Northern region average approximately 58-85% of their designed capacity. The reservoirs currently operating with spillways are: Nui Coc reservoir (Thai Nguyen) with a discharge rate of 150 m3/s, and Cam Son reservoir (Bac Ninh) with a discharge rate of 9 m3/s.

The water levels in reservoirs in the North Central region are at an average level, with the average capacity of the reservoirs reaching 56-86% of their design capacity. The reservoirs currently operating with spillway discharges are: Cua Dat reservoir (Thanh Hoa) with a discharge rate of 171 m3/s (for power generation); Boc Nguyen reservoir (Ha Tinh) 5 m3/s; and Ta Trach reservoir (Hue) 80 m3/s (for power generation).

For reservoirs managed by the Ministry of Agriculture and Environment, the Cua Dat reservoir had a water level of 61% of its designed capacity at 5 PM on July 21st, with a total discharge of 171 m3/s through power generation; the reservoir still has 797.40 million m3 for flood storage.

Ngàn Trươi Reservoir currently has a water level at 31% of its designed capacity; it still has 535.97 million m3 of water for flood storage. Tả Trạch Reservoir has a water level at 94% of its designed capacity; it still has 249.5 million m3 of water for flood storage, with a total discharge rate of 80 m3/s through power generation.

Rainfall forecast from the evening of July 21st to July 23rd: The Northeast region, the Northern Delta, Thanh Hoa and Nghe An will experience heavy to very heavy rain and thunderstorms, with total rainfall generally ranging from 200-350 mm, and exceeding 600 mm in some areas. Other areas of Northern Vietnam and Ha Tinh will experience moderate to heavy rain, with localized very heavy rain, with total rainfall generally ranging from 100-200 mm, and exceeding 300 mm in some areas.

On the night of July 21st and during the day of July 22nd, the area from Quang Tri to Hue will experience scattered showers and thunderstorms, with localized heavy rain (10–30 mm), and in some places over 70 mm (concentrated in the afternoon and evening).

The Department of Water Resources Management and Construction recommends that localities and units monitor water level changes and the condition of structures, paying particular attention to vulnerable reservoirs, reservoirs with sluice gates, and downstream areas with dense populations when it rains in the reservoir's catchment area.

For ongoing construction projects, appropriate construction plans must be in place to ensure no incidents occur, and absolutely no items that do not meet the construction schedule should be implemented before the flood season. Units operating water reservoirs must adhere to approved operating procedures; reservoirs with floodgates must adjust water levels to ensure structural safety and avoid abnormal flood releases that could endanger downstream areas; simultaneously, water storage must be carried out appropriately in reservoirs with low storage capacity; and early warning systems must be strictly implemented for downstream residents before reservoir flood releases and when there is a risk of incidents.

The relevant units will maintain a 24/7 duty roster during periods of rain and flooding; they will deploy personnel on standby at construction sites at risk of failure and at reservoirs with full water levels to promptly handle unusual situations according to the "four on-the-spot" principle when there is a risk of construction failure.
