To ensure the safe operation of water discharge from Nam Giai hydropower reservoir in accordance with the approved Single Reservoir Procedure and Inter-reservoir Procedure on the Ca River Basin, Viet Lao Investment and Construction Joint Stock Company announces the expected operation and regulation plan for Nam Giai hydropower reservoir as follows:

The expected time to start discharging water is from 4:00 a.m. on August 31, 2025 , with a total flow rate from 13.55 m³/s to 500 m³/s.
