Hydropower plants on the Chay River basin announced flood discharge with a flow downstream of more than 1,000 m3/s.

Due to the impact of heavy rains over the past two days, water from upstream has continuously poured in, causing the water levels of hydroelectric reservoirs to rise. To ensure safe operation of the plant and safety of the downstream area, hydroelectric plants in the Chay River basin have announced the release of floodwater from their reservoirs, of which some hydroelectric plants have increased the discharge level to more than 1,000 m3/s.

Accordingly, at 10:00 p.m. on September 29, Bac Ha Hydropower Joint Stock Company announced that the discharge flow through the spillway was 671.66 ^m3 /s; the flow through the generator was 187.20 ^m3 /s; the total discharge flow downstream was 858.86 ^m3 /s.

Bac Ha Hydropower Plant increases discharge flow due to increasing water flow from upstream.

Along with Bac Ha Hydropower Plant, on the evening of September 29, hydropower plants on the Chay River basin, including Bao Nhai Hydropower Plant Level 1, Bao Nhai Hydropower Plant Level 2, Nam Luc Hydropower Plant, Vinh Ha Hydropower Plant, Phuc Long Hydropower Plant, and Thac Ba Hydropower Plant also announced an increase in flood discharge to the downstream compared to previous days.

Specifically, Bao Nhai Hydropower Plant Level 1 announced that at 9:53 p.m., the total flood discharge to the downstream was 752 ^m3 /s. The plant is operating normally, ensuring safety.

Hydroelectric dams release floodwaters causing water levels on the Chay River to rise.

Bao Nhai Hydropower Plant Level 2 announced at 22:03, the total flow downstream is 817 ^m3 /s.

Nam Luc Hydropower Plant announced at 10:00 p.m. that the total discharge to downstream was 1,008 ^m3 /s.

Vinh Ha Hydropower Plant announced at 22:03, the total discharge to downstream is 1,155 ^m3 /s.

Phuc Long Hydropower announced at 22:06, the total discharge flow to the downstream is 1,295 ^m3 /s, by 0:30 on September 30, the discharge flow will increase from 1,600 ^m3 /s - 2,650 ^m3 /s.

Thac Ba Hydropower Plant announced that at 10:00 p.m., the total water flow to the lake was 4,110 ^m3 /s, the total flow downstream was 366 ^m3 /s.

Localities downstream of the hydropower plant are urgently moving people to safety.

Faced with the situation of hydropower plants simultaneously releasing floodwaters, causing the water level on the Chay River to rise, localities downstream of hydropower plants are urgently deploying, checking, and reviewing, while continuing to propagate and instruct people on how to prevent and avoid, ensuring the safety of life and property.
