As of 8:00 a.m. on October 24, 2025, according to an update from Vietnam Electricity Group, Hoa Binh Lake recorded upstream water levels at elevation of 115.79 m; water flow to the lake reached 1,309 m3/s; total discharge was 737 m3/s.
Implementing the inter-reservoir operation process in the Red River basin, Hoa Binh Hydropower Plant closed a bottom spillway gate at 11:00 on October 22 to stabilize downstream flow. When closing a bottom spillway, the downstream water level will gradually decrease.
At Tuyen Quang Lake, by 8:00 a.m. on October 24, the upstream water level reached 118.02 m; the water flow to the lake reached 574 m3/s; the total discharge was 1,211.51 m3/s. Implementing the inter-reservoir operation process in the Red River basin, Tuyen Quang Hydropower Plant opened 1 bottom spillway gate of Tuyen Quang Hydropower Plant at 6:00 p.m. on October 21.
As of 8:00 a.m. on October 24, Son La Lake had an upstream water level of 215.05 m; water flow to the lake was 1,065 m3/s; total discharge was 1,432 m3/s. Currently, the unit has closed all bottom spillways, only maintaining power generation through generators to regulate the flow downstream.
A similar situation occurred in Lai Chau Lake, where the upstream water level reached 294.99m; the water flow to the lake reached 1,001m3/s; the total discharge was 1,101m3/s. Currently, Lai Chau Hydropower Plant has also closed all bottom spillways, only operating power generation.
At Thac Ba Lake, by 8:00 a.m. on October 24, the upstream water level reached 57.96 m; the water flow to the lake reached 280 m3/s, the total discharge was 322.77 m3/s. Currently, Thac Ba Hydropower Plant maintains open 1 spillway.
In the context of complicated heavy rain, the flexible operation of hydroelectric reservoirs, ensuring safety downstream is considered a key factor in natural disaster prevention in the North.
