Heavy rainfall across wide areas of the northern region from May 21-28 has helped raise water levels in rivers and hydropower plant reservoirs, improving the electricity supply in North Vietnam.
The National Hydro Meteorological Forecasting Centre said that the northern region saw heavy rainfall from May 21-28, which caused water levels to rise in the Lo, Thao, Boi, Cau, Luc Nam, Hong and Ma Rivers, resulting in flooding in some areas.
Water levels were the highest along the Gam River, measuring 3.9 metres and 7.2 metres along the Buoi River. The lower reaches of the Hong and Ma River swelled up by 1-2 metres.
The increase in water levels helped fill up large volumes of water in the Son La, Thac Ba, Hoa Binh and Tuyen Quang hydropower plants reservoirs, improving the electricity supply from these plants.
