According to data from Vietnam Electricity Group, at 12:00 on May 9, in the Northern region, reservoirs on the Da River system continued to record quite good water inflow.
Son La Lake has a water level of 203.94 m, a water inflow of 221 m3/s and a total discharge output of 482 m3/s. Hoa Binh Lake reached a water level of 106.99 m, a water inflow of 366 m3/s, and a total discharge output of up to 1,139 m3/s.
Thac Ba Lake also maintains power generation with a discharge flow of nearly 291 m3/s. This development shows that the upstream water source is improving, creating conditions to increase power generation and ensure downstream flow.
In the Northeast area, Tuyen Quang reservoir has a water level of 110.29 m, a water inflow of 50 m3/s and has not generated discharge. Meanwhile, Northwest reservoirs such as Lai Chau, Ban Chat and Huoi Quang continue to accumulate water, with water inflow fluctuating from 17–313 m3/s.
The North Central region in general operates stably. Trung Son and Ban Ve reservoirs maintain water levels at safe levels, with inflow reaching 94–134 m3/s. Khe Bo reservoir has resumed power generation with a total discharge flow of 170.8 m3/s.
In the Central region, most hydropower reservoirs are stocking water and generating electricity at a low to medium level. Some reservoirs such as Vinh Son A still maintain power generation, while many other reservoirs such as Song Bung 4, Vinh Son B and Vinh Son C almost do not generate discharge.
In the Central Highlands region, many reservoirs continue to operate for stable power generation. Some reservoirs with remarkable discharge flows include Pleikrông (122 m3/s), Thượng Kon Tum (26.55 m3/s) and Buôn Kuốp (15.82 m3/s). Reservoirs on the Se San and Serepok systems maintain water levels at a safe level.
In the Southeast region, Tri An reservoir recorded a water flow of 230 m3/s and a total discharge output of 236 m3/s, continuing to ensure power supply and downstream regulation.
According to the forecast of the National Center for Hydro-Meteorological Forecasting, on May 9, the Northwest region will have scattered showers and thunderstorms, with locally heavy rain. Other areas in the North will have showers and thunderstorms in some places. The meteorological agency warns of the risk of extreme phenomena such as thunderstorms, tornadoes, lightning, hail and strong gusts of wind.
The Southern region in the late afternoon and night has showers and thunderstorms in some places; sunny during the day, hot in some places, especially the East has hot sun.
