According to data from Vietnam Electricity Group, at 3:00 PM on March 18, in the Northeast region, Tuyen Quang Lake reached 114.74m, about 5.3m lower than the normal water level (120m).
The water flow to the reservoir is at 50 m3/s, while the total discharge volume reaches 121.35 m3/s, all through turbines, no overflow is generated.
In the Northwest region, large reservoirs on the Da River system continue to store water well. Lai Chau Lake reached 294.44m, only 0.56m lower than the normal water level.
Son La Lake reached 214.38m, approaching the normal water level of 215m; water inflow to the lake reached 1,194 m3/s, total discharge reached 1,649 m3/s.
Hoa Binh Lake maintains a water level of 115.02m, nearly 2m lower than the normal water level of 117m. Notably, the water flow to the lake is at a high level of 1. 512 m3/s, while the total discharge is only 488 m3/s, showing that the lake is increasing water storage.
Some other reservoirs such as Huoi Quang (368.63m/370m) and Ban Chat (440.93m/475m) also recorded high water levels. However, the total discharge volume at these two reservoirs is 339 m3/s and 241 m3/s respectively, much higher than the inflow, reflecting regulation for power generation.
At Thac Ba Lake, the water level reached 54.88m, 58m lower than the normal water level. The inflow to the lake was at 85 m3/s, but the total discharge amount reached 454.86 m3/s, many times higher than the inflow.
According to the National Center for Hydro-Meteorological Forecasting, the weather forecast for March 18th, the Northern region has light rain in some places, early morning fog and light fog scattered, sunny skies in the afternoon. Cold at night and in the morning.
