Heavy rains are causing flooding and landslides in many areas of Cao Bang province.

According to information from specialized agencies, due to heavy rain, from 7:00 AM to 8:00 AM on June 26th, the water level of the Bang River increased at a rate of approximately 95 cm/hour.

At the Bang Giang Hydrological Station at 8:00 AM, the measured water level was 179.91m, about 0.59m lower than alarm level 1, but it was rapidly rising.

Given this situation, residents in the hamlets of Ma Quan, Na Teng, Thai Cuong, Thanh Hung, and Ban Don (Hoa An commune) were advised to proactively move their property, livestock, and vehicles to higher, safer places; and to constantly monitor weather developments and water levels.

They were also advised to avoid areas with deep flooding and strong currents, and to remind children not to play near rivers and streams to prevent accidents.

On the same day, the Tien Thanh Hydropower Plant (Hanh Phuc commune) issued an urgent notice regarding flood release due to heavy rain in the catchment area and water flowing from upstream into the reservoir.

Flooding caused widespread inundation in the riverside area. 

According to the announcement, at 9:30 AM on June 26th, the inflow into the reservoir reached 260 m³/s, with the water level at 157.4 m. It is predicted that the inflow will continue to increase to 500 m³/s by 10:00 AM.

The power plant began regulating the water flow from 10:00 AM on the same day with a total discharge of 500 m³/s, including 243.22 m³/s through the spillway and 256.78 m³/s through the turbines.

The unit predicts that the water level in the downstream area may rise by approximately 0.5 m, affecting some areas in the communes of Hanh Phuc, Thach An, Phuc Hoa, and Hoa Thuan.

The power plant requests that local authorities widely inform the public to avoid going to the riverbanks during the flood discharge and to proactively implement disaster prevention and control measures.

Flood levels on the rivers are rising very rapidly.

Meanwhile, the Binh Long Hydropower Plant also issued an urgent notice regarding reservoir regulation due to heavy rainfall in the catchment area.

According to the plan, the plant began releasing water at 4:00 AM on June 26th to maintain the reservoir water level at 209.8m. At 4:00 AM, the inflow into the reservoir was approximately 100 m³/s, forecast to increase to 200 m³/s by 5:00 AM. The total discharge reached 130.18 m³/s, including 90.76 m³/s through the spillway and 41.09 m³/s through the turbines.

The regulation is predicted to cause the water level in Pac Gay hamlet, Hoa An commune to rise by about 0.6m. Water will reach this area almost immediately after the release and, about 30 minutes later, will merge into the Bang Giang River at the head of the bridge in Hong Viet commune (formerly).
