Discharging water from Ban Ve Hydropower Reservoir to respond to storm No. 9

According to the Operation Order, the Head of the Civil Defense Command of Nghe An province has just issued Official Dispatch No. 931/BCH dated September 23, 2025 requesting the Director of Ban Ve Hydropower Company to deploy the operation of releasing water from the reservoir downstream with a flow rate of 400 m³/s to 800 m³/s, starting from 8:00 a.m. on September 24, 2025. The goal is to proactively lower the reservoir water level to welcome the big flood that is likely to appear from the afternoon of September 25 to the morning of September 26.

Specifically, according to forecasts, in the next 24 hours, water flow to Ban Ve hydropower reservoir may reach 250 - 300 m³/s, and may increase to 800 m³/s from September 25.

If during operation, the water flow to the reservoir increases above 1,000 - 1,200 m³/s or the water level at Con Cuong and Cho Trang hydrological stations exceeds alarm level II, Ban Ve Hydropower Company will have to adjust the operating mode to cut and reduce floods downstream, in accordance with the regulations in the Inter-reservoir Operation Procedure approved by the Prime Minister.

Notably, if the reservoir water level reaches 200m, the Company must gradually adjust the discharge flow to balance with the flood flow, ensuring the safety of the project. When hydrometeorological conditions return to normal, specifically when the flow to the reservoir decreases below 1,000 m³/s and there is no forecast of heavy rain or flood in the next 10 days, the reservoir will return to normal operation mode.

The Provincial Civil Defense Command also requested specialized agencies such as the Department of Agriculture and Environment, the Department of Industry and Trade and related units to strengthen supervision and inspection of the implementation of operating orders, ensure compliance with regulations and minimize possible damage to downstream areas.

People in downstream communes are advised to closely monitor official information from authorities and proactively prepare prevention and response plans when bad situations occur.

This is an important and timely step in the work of preventing and fighting natural disasters and protecting the lives and property of people in Nghe An province.
