Northern region operates 94 stations to drain water

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

Currently, Phu Tho has 11.8 hectares of flooded, damaged, and broken rice, crops, and fruit trees. Other localities are continuing to update.

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

Regarding the situation of irrigation reservoirs, the current water storage capacity in irrigation reservoirs in the Northern region is on average about 58 - 85% of the design capacity. The reservoirs currently operating spillway discharge: Nui Coc reservoir (Thai Nguyen) with a discharge flow of 150 m3/s, Cam Son reservoir (Bac Ninh) with a discharge flow of 9 m3/s.

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

With reservoirs managed by the Ministry of Agriculture and Environment, Cua Dat reservoir had a water level at 5:00 p.m. on July 21 reaching 61% of its design capacity, with a total discharge of 171 m3/s through power generation; the reservoir still has 797.40 million m3 for flood storage.

Ngan Truoi Lake has a current water level of 31% of its design capacity; the lake still has 535.97 million m3 for flood storage. Ta Trach Lake has a water level of 94% of its design capacity; the lake still has 249.5 million m3 for flood storage, with a total discharge of 80 m3/s for power generation.

Rainfall forecast from the evening of July 21 to July 23, the Northeast region, the Northern Delta, Thanh Hoa and Nghe An will have heavy to very heavy rain and thunderstorms, with total rainfall ranging from 200-350 mm, with some places over 600 mm. Other areas of the North and Ha Tinh will have moderate rain, heavy rain, and locally very heavy rain with total rainfall ranging from 100-200 mm, with some places over 300 mm.

On the night of July 21 and 22, the area from Quang Tri to Hue will have scattered showers and thunderstorms, locally heavy rain (10-30 mm), in some places over 70 mm (concentrated in the afternoon and evening).

The Department of Irrigation Project Management and Construction recommends that localities and units monitor water level changes 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 projects under construction, there must be a suitable construction plan to ensure that no incidents occur, and absolutely no items that do not meet the construction progress of flood control must be implemented. Units must operate reservoirs in accordance with approved operating procedures; reservoirs with flood discharge gates must adjust the reservoir water level to ensure the safety of the project and not discharge flood water abnormally, causing unsafety to downstream areas; at the same time, properly store water for reservoirs with low storage capacity; strictly implement early warnings to downstream people before reservoirs discharge flood water and when there is a risk of incidents.

Units organize 24/7 duty during times of rain and floods; arrange permanent personnel at construction sites at risk of incidents, reservoirs full of water to promptly handle unusual situations according to the "4 on-site" motto when there is a risk of construction incidents.
