Large reservoirs such as Lai Chau, Son La, and Hoa Binh all have lower water levels than normal water levels.
Notably, Hoa Binh reservoir discharged up to 409 m3/s through the plant, while Thac Ba reservoir discharged 286.03 m3/s to serve power generation.
In the North Central region, Khe Bo reservoir has a fairly large inflow of water to the reservoir, reaching 194.8 m3/s and discharging 171 m3/s.
Trung Son Lake is also generating electricity with a total discharge rate of 87 m3/s, while Ban Ve and Quang Tri reservoirs have not yet discharged water.
The South Central Coast region recorded a large number of reservoirs with low flow. Some reservoirs still generate electricity such as A Vuong discharging 28 m3/s, Song Bung 4 discharging 49 m3/s, Vinh Son A discharging more than 10 m3/s. Song Hinh reservoir continues to generate electricity with a discharge flow of 15.22 m3/s.
In the Central Highlands, some lakes maintain electricity generation operations such as Pleikrong discharging 78 m³/s, Upper Kon Tum discharging 26.46 m³/s, Se San 4 discharging 10 m³/s. Buon Kuop Lake discharges 15.28 m³/s; Some other lakes have not released water yet.
In the Southeast region, Tri An reservoir has a large inflow of water to the reservoir, reaching about 200 m3/s, and has not yet discharged water.
