In a dispatch issued on 22/11, the Lam Dong Department of Agriculture and Environment directed the Hydropower Companies Da Nhim - Ham Thuan - Da Mi, Dai Ninh, Trung Nam, Dong Nai, and Dong Nai 5 - TKV to increase regulated discharge downstream. This discharge will exceed the inflow to the reservoirs, aiming to drain the basin and create additional flood prevention storage capacity.
Specifically, the Don Duong reservoir is to maintain a maximum discharge rate of 400 m3/s, while the Dai Ninh reservoir will discharge approximately 600 m3/s. Dong Nai 2 and Dong Nai 3 reservoirs will regulate their total discharge not exceeding 700 m3/s and 800 m3/s respectively. The Dong Nai 5 reservoir is instructed to operate with a discharge rate approximately 10% greater than its inflow.

This action comes as soil moisture in many areas of Lam Dong has reached or is near saturation, with levels over 85%. Furthermore, forecasts indicate continued rainfall in the near future. The National Center for Hydro-Meteorological Forecasting is also tracking a low-pressure area off the Philippines, which could enter the South China Sea on 26-27/11 and strengthen into a tropical depression or storm number 15.
The Lam Dong Department of Agriculture and Environment also urged communes, including Ninh Gia, Tan Hoi, Duc Trong, Bao Lam 4, Bao Lam 5, Cat Tien, Cat Tien 2, Da Teh, D'Ran, Ka Do, Quang Lap, and Don Duong, to inform downstream residents of the water release plan for prevention.
Recent floods in Lam Dong resulted in 5 fatalities and displaced over 1,137 households. The province recorded approximately 1,640 ha of damaged crops, primarily vegetables, with D'Ran (300 ha), Ka Do (150 ha), Quang Lap (150 ha), and Quang Phu (over 50 ha) being the most affected areas.
Across the province, 33 landslides were reported, and many roads were deeply flooded and cut off, complicating rescue efforts and the transport of essential supplies. Initial damages to homes, crops, livestock, and aquaculture are estimated at approximately VND 1,000 billion.
