Specifically, the Head of the Provincial Civil Defense Command agreed with the request that the owner of Ba Ha River hydroelectric reservoir operate with a discharge rate smaller than the flow to the reservoir to store water up to the design flood level of 105.96 m to reduce floods downstream, and when the reservoir water level reaches the elevation. 105.96 m, the project management unit will operate and regulate the water level with a total discharge equal to the total water flow to the lake. Leaders of Dak Lak province requested the owners of Song Hinh and Krong HNang lakes to operate based on actual conditions to reduce floods downstream and ensure project safety. In addition, the reservoir owners are fully responsible for the operation of the reservoirs and absolutely do not let unsafe dams occur. The Ba Ha River hydroelectric reservoir discharges 16,100 m3/s downstream. Regarding the water level at the hydroelectric reservoirs, according to the report of the Department of Agriculture and Environment of Dak Lak province, the Ba Ha River hydroelectric plant at 4:00 p.m. on November 19, the lake water level (MNH) is 105 m; flow to the lake 16,120 m3/s; Total flow discharged downstream is 16,100 m3/s (including engine flow of 300 m3/s, spillway discharge of 15,800 m3/s). Hinh River at 12:00 on November 19, MNH is 208.77 m; flow to the lake 2,229 m3/s; Total flow discharged downstream is 1,349 m3/s (including engine flow 49m3/s, spillway discharge 1,300 m3/s). Srepok 3 at 2:00 p.m. on November 19, MNH is 271.08 m; flow to the lake 951.00 m3/s; Total discharge flow downstream is 953.00 m3/s (including engine flow of 406.00 m3/s, overflow discharge of 547.00 m3/s). Ba River flood is likely to exceed the historical flood level of 1993. According to forecasts from the Dak Lak Provincial Hydro-meteorological Station, on communes/wards in the Eastern region of the province from the evening of November 19 to the evening of November 21 There continues to be very heavy rain and thunderstorms, with total rainfall commonly ranging from 200 - 300mm, in some places greater than 500mm.

In the next 24 hours, floods on the Ky Lo, Tam Giang and Ban Thach rivers are slowly decreasing, but still remain at a high level. Downstream of Ba River continues to rise, the flood peak water level at Cung Son station is likely to exceed the historical flood level in 1993 by 1 - 1.3 m, at Phu Lam station, the flood peak water level is likely to exceed the historical flood level in 1993 by 0.2 - 0.4 m. On the Sre Pok river basin, the flood water level continues to rise and fluctuate at a high level. Ban Don station fluctuates at level 1 - level 2, Giang Son station flood level continues to increase, possibly reaching 0.5 - 0.8m above level 2, Krong Buk station fluctuates at level 2 - level 3. 22,938 houses were flooded, 1,123 households were isolated. According to quick reports from localities in Dak Lak province on the damage caused by heavy rain, by 4:00 p.m. November 19, Dak Lak province had 1 person died in Song Cau ward; 8 houses collapsed and were swept away in Tong Rang A village, Tong Rang A village and Ra Han village, Yang Mao commune.
