Many reservoirs in the East of Lam Dong increased discharge due to prolonged heavy rain.

Due to heavy rain from the evening of December 3 to the early morning of December 4, many reservoirs in the eastern part of Lam Dong province had to increase their discharge capacity to ensure the safety of the works. The communes and wards in the downstream areas have been notified to proactively respond.

Therefore, to ensure the safety of the project in the context of continued rain in the Song Quao reservoir basin, Binh Thuan Irrigation Works Exploitation Company Limited will continue to increase the discharge flow through the spillway to lower the lake water level. The regulation is expected to start from 6:00 a.m. on December 4, with the discharge flow increased to 350 - 500 m³/s depending on the amount of water flowing into the lake and the downstream situation.

In order to maintain flood prevention capacity, ensure safety for the project and reduce the risk of flooding in downstream areas when heavy rain continues, the Company will operate to regulate water through the spillway of Suoi Da reservoir from 10:30 a.m. on December 4, with an initial discharge flow of 1-3 m³/s. After that, depending on the amount of water flowing into the reservoir and downstream developments, the discharge flow will be adjusted to increase in the range of 5-50 m³/s.

To avoid damage to people in affected areas, the Company requests the People's Committees of relevant communes and wards to notify people in the downstream areas of the Song Quao reservoir dam (along the Cai River) and the river mouth; downstream areas of the Long Song reservoir, downstream areas of the Suoi Da reservoir dam... to know the situation and proactively take safety prevention plans.
