Increasing the spillway level of Buôn Tua Srah hydropower reservoir

Buon Kuop Hydropower Company said that due to heavy and prolonged upstream rains, the amount of water flowing into Buon Tua Srah Hydropower Reservoir increased, so the unit had to increase the spillway discharge level.

From mid-afternoon until now, heavy to very heavy rain has occurred in the upstream of the reservoir, water level in Krong No 3 reservoir in the upstream has increased, reaching more than 1,500 m3/s and will continue to increase in the coming time.

It is expected that at around 2 a.m. on November 20, the flood will reach Buon Tua Srah Lake and may reach 2,000 m3/s, possibly higher.

From 5:00 p.m. on November 19, Buon Kuop Hydropower Company proactively increased the spillway discharge level, with a flow rate of 540 m3/s, plus the machine flow rate, the total water discharge to the downstream was 710 m3/s (the highest total discharge level during storm 13 was on November 7 at 650 m3/s).

Buon Tua Srah Hydropower Reservoir is spilling over.

According to monitoring data at 8:00 p.m. on November 19, the water level of Buon Tua Srah Lake was nearly 487.2 m, the water flow into the lake was 536 m3/s, and the total discharge to the downstream was 659.3 m3/s.

The flood peak at the reservoir is forecasted to occur at 8:00 a.m. on November 20, 2025. With the above monitoring and forecast parameters for the reservoir in case of an unusual flood season, it is expected that the reservoir owner will maintain this discharge level or possibly higher.

Buon Kuop Hydropower Company informs the authorities and people in the downstream area to proactively prevent floods when they come.

For communes in the confluence area of ​​Krong No and Krong Ana rivers, they are also affected by floods from the Krong Ana river branch, which are also continuing to increase.

The company is continuing to monitor the flood situation to adjust the reservoir accordingly to cut and reduce the flood for this flood.
