As of 7:00 a.m. on December 12, 2025, according to an update from Vietnam Electricity Group, at Tuyen Quang Hydropower Reservoir, the upstream water level reached 119.64 m, near normal rise. Total discharge is 184.88 m3/s, all through the plant.
In the Northwest area, Lai Chau Lake recorded upstream water levels of 292.99 m, discharging 254 m3/s through the plant.
Ban Chat Lake on the morning of December 12 reached 474.50 m, close to normal water level (475 m). However, the flow to the reservoir is only 12 m3/s, so the plant does not generate discharge through the dam and discharge through the generator.
Huoi Quang Lake is also in a similar situation when the water level reached 369.64 m (near the normal increase of 370 m), but the flow is only 17 m3/s, not causing discharge.
At Son La Lake, the water level is 214.76 m, the total discharge is 995 m3/s, all through the plant to optimize power generation.
Hoa Binh Lake maintains a water level of 116.20 m, discharging 632 m3/s.
Thac Ba Lake recorded a water level of 57.90 m, no discharge.
