Emergency flood warning in southern Khanh Hoa province

On the afternoon of November 19, Ninh Thuan Irrigation Works Exploitation Company Limited issued an urgent warning about the flood discharge situation at many reservoirs in the southern part of Khanh Hoa province after the water level continued to rise due to prolonged heavy rain. Compared to 7:00 a.m., by 2:00 p.m. on the same day, many reservoirs had to increase the discharge flow, potentially causing flooding downstream.

Song Trau Lake (Cong Hai commune) capacity reaches 98.6%, currently 2 gates open, spillway ^141.08m3 /s.

At Song Cai Lake, the overflow flow increased from 466m³/s to 801.84m³/s, an increase of nearly 336m³/s, due to the lake's continued high water level. This is a large discharge level, potentially increasing the risk of flooding in riverside areas. Song Sat Lake also increased its discharge from 102.2m³/s to 197.88m³/s, nearly double that of the morning. At Tra Co Lake, the discharge flow increased from 22.96m³/s to 175.08m³/s, an increase of more than 152m³/s, showing an unusually large amount of water flowing into the lake. At the same time, many other lakes also increased their discharge sharply, including: Phuoc Trung from 0.95m³/s to 10.61m³/s; Buffalo River from 51.76m³/s to 141.08m³/s; Freshwater from 9.29m³/s to 45.11m³/s; Cho Mo from 14.04m³/s to 163.4m³/s, an increase of more than 11 times; Than River from 59.75m³/s to 95.55m³/s.

The company said that due to the continued heavy rainfall in the past hours, many reservoirs reached 95-110% of their design capacity, forcing them to open additional sluice gates to ensure the safety of the project. The increased discharge could cause rapid flooding in low-lying areas, riverside areas and areas that were already flooded.

The company recommends that people limit movement through culverts, streams, and rivers; closely monitor rain and flood warning information; proactively move assets away from areas at risk of deep flooding and fast-flowing water. Downstream localities need to prepare response plans and proactively evacuate when required.
