Around 4:30 PM, water in the Dong Nai River rose, overflowing the embankment along Nguyen Van Tri street, in front of Bien Hoa market, Tran Bien ward. Many riverside sections were submerged, hindering residents' travel and business activities.

According to the Dong Nai Hydro-Meteorological Station, the water level at the Bien Hoa station this afternoon reached 2.2 meters, hitting alarm level three. This level is one centimeter higher than the historical peak recorded in 2000, making it the highest tide observed in the area over the past 26 years.

Nguyen Van Tri street resident, Mr. Tan, 78, stated he rarely witnesses the river rising high enough to breach the embankment. "Most houses here have elevated foundations, so they haven't been heavily affected yet, but the flooded roads make commuting difficult", he said.

Beyond central Bien Hoa, the high tides also caused localized flooding in Tran Bien, Tam Hiep, and Long Hung wards. Numerous roads, alleys, and houses in low-lying areas were submerged by nearly half a meter, disrupting daily life.

This flooding event coincided with rising high tides on the Dong Nai River and the Tri An Hydropower Plant's controlled water release from its reservoir.

To mitigate downstream impact, the Tri An Hydropower Company reduced the discharge rate through its spillway from 879 to 732 cubic meters per second, starting at 2 PM on 10/10. Including water passing through power-generating turbines, the total flow to downstream areas fluctuates between 1,192 and 1,532 cubic meters per second, depending on operational mode.

The meteorological agency forecasts that high tides in the lower Dong Nai River will persist at elevated levels on 11-12/10. Peak tides are expected between 5-8 AM and 5-8 PM, posing a risk of continued inundation for low-lying riverside areas.

Concurrently, high tides also flooded numerous areas in Ho Chi Minh City, including the city center, southern parts, and former Binh Duong. Rising water inundated roads and residential zones, with some areas submerged by nearly half a meter, severely impacting residents' travel and daily routines.
