Water levels on many rivers in the North are decreasing but remain dangerously high. The Cau and Ca Lo rivers passing through Hanoi are still above alert level 3.

According to the Department of Dyke Management and Natural Disaster Prevention ( Ministry of Agriculture and Environment ), as of noon on October 12, Hanoi and Bac Ninh still had more than 5,360 flooded houses, a decrease of more than 2,300 compared to the same morning.
However, by the afternoon of October 12, many areas along the Cau River such as Da Phuc and Trung Gia (Hanoi) were still deeply flooded, with dikes and drainage systems under great pressure.

In Bac Ninh, the flood has subsided but the local authorities are still monitoring the dike and dealing with minor problems. In Thai Nguyen, the floodwaters have basically receded, with only a few low-lying communes such as Phu Binh, Diem Thuy, and Van Xuan submerged about 0.5m. The damage in this locality is estimated at about 4,000 billion VND. Cao Bang suffered about 2,000 billion VND in damage, but the specific figures are still being reviewed.
The National Center for Hydro-Meteorological Forecasting said that in the next 1-2 days, floodwaters in the North will continue to decrease, but low-lying areas and river banks will still be flooded from 0.2 to 1 meter, and deeper in some places. The flooding may last another 1-3 days. The meteorological agency warned of the risk of dyke erosion, damage to bridges, roads and riverside structures when the flood recedes.

According to the National Center for Hydro-Meteorological Forecasting, worryingly, from the night of October 13 to 16, the North may experience a new round of rain. Rain concentrated in the Northeast region (which has just experienced a historic flood) may cause river water levels to rise again, causing further damage to areas recovering from natural disasters.
The Ministry of Agriculture and Environment has asked localities: Hanoi, Bac Ninh, Lang Son to strengthen monitoring of key dike points, promptly handle seepage, leakage, landslides and need to prepare response plans if heavy rains return.
At the same time, localities need to urgently mobilize forces and volunteer organizations to support production restoration, repair houses and schools, and stabilize people's lives.

To reduce water pressure downstream of Lo River and Red River, on October 12, Deputy Minister of Agriculture and Environment Nguyen Hoang Hiep signed a dispatch requesting Tuyen Quang Hydropower Company to close one bottom spillway gate from 4 p.m. the same day. Updated on the Vietnam Electricity Group system at 5 p.m., the plant only maintained one deep spillway gate.
