In all three discharge times, Hoa Binh, Tuyen Quang and Thac Ba hydropower reservoirs under Vietnam Electricity (EVN) have discharged a total of 5.14 billion m3, providing sufficient water for the 2020 - 2021 winter-spring crop cultivation in the Midlands and Northern Delta provinces. Compared with the original plan, the total amount of water discharge has decreased by about 0.5 - 0.7 billion m3. The total amount of discharged water this year has declined against the plan, however is still 2.46 billion m3 higher than that of 2020 (the year with heavy rain on the Lunar New Year Eve) and 0.72 billion m3 higher than that of 2019.
