On November 19, the Dak Lak Provincial Civil Defense Command informed that the Song Ba Ha Hydropower Plant has raised water regulation to nearly 13,000 m3/s. The country's regulation level is considered the highest in the past 10 years.
It is forecasted that Song Ba Ha Hydropower Plant can increase water regulation to 14,000 m3/s, equal to the historical flood regulation level in 2009.
The Ba Ha River Hydropower Plant is releasing floodwaters in large quantities due to heavy rain from the upstream of the Ba River basin. Thereby, ensuring the operation of reservoirs and avoiding risks.
According to research, on the Serepok River, the water level at 10:00 at stations: Krong Buk above alert level 1 is 0.31m, Giang Son station - Krong Ana river above alert level 2 is 0.08m, Ban Don below alert level 2 is 0.6m.
On the Ba River, the water level fluctuates according to the regulation of hydropower plants and irrigation lakes. The water level at 10:00 at Cung Son station was above alert level 3 at 3.01m, Phu Lam below alert level 3 at 0.73m. On Ban Thach River at Hoa My Tay station, it reached alert level 3.
In the next 6 - 12 hours, floods in the Ky Lo, Tam Giang rivers and the downstream of the Ba river will continue to rise.
On Ban Thach River, the level from alert level 3 to above alert level 3 is 1.6m. In the Serepok River basin, the flood level continues to rise and fluctuate at a high level, at Ban Don station it is likely to reach approximately alert level 2 and Giang Son station will fluctuate at a level 0.2 - 0.4m above alert level 2.
The management unit of large hydroelectric reservoirs in the province is closely monitoring the storm situation to regulate water, ensure safe operation of the project, minimize damage to downstream areas.
