In particular, Prenn Pass, the gateway to Da Lat urban area, suffered a serious landslide in the early morning of November 17, with the landslide spreading to the negative slope and reaching the center of the road of this 4-lane wide pass. Currently, the Traffic Police of Lam Dong Province Police have regulated traffic going in the direction of Mimosa Pass to ensure traffic safety.

Landslides also occurred at many locations on Gia Bac and Ngoan Muc passes. Currently, the route through Khanh Le and Ngoan Muc passes (connecting Lam Dong - Khanh Hoa) from Lam Dong is closed to traffic due to the high risk of further landslides. The entire Ngoan Muc pass has 12 landslides, causing vehicles to be stuck all night.

From the night of November 16 to the morning of November 17, the Eo Gio Traffic Police Team (Traffic Police Department of Lam Dong Provincial Police) and the rescue force of D'Ran Commune (Lam Dong) proactively went down to Ngoan Muc Pass near Lam Dong to clear landslides and fallen trees on the road. By 8:30 a.m. on November 17, the rescue forces had basically cleared the landslides and fallen trees on Ngoan Muc Pass so that vehicles could circulate.

In the face of prolonged rain over the past two days, on November 17, the Department of Agriculture and Environment of Lam Dong issued Document 6403/SNNMT-TLTNN on the operation of Dai Ninh Hydropower Reservoir to reduce flooding downstream. Accordingly, at 9:00 a.m. on November 17, the water level of Dai Ninh Reservoir reached 879.816 m (normal water level is 880 m); inflow into the reservoir was 475 m3/s, machine flow was 55 m3/s, and regulated discharge flow through the spillway was 350 m3/s.

Based on the rain situation in the Dai Ninh and Don Duong lake basins under the direction of the Department of Agriculture and Environment of Lam Dong province, Dai Ninh Hydropower Company has increased the regulated discharge flow through the spillway of Dai Ninh lake from 10:00 a.m. on November 17 from 350m3/s to between 400m3/s and 500m3/s to operate and reduce floods downstream. The above-mentioned regulated discharge water from Dai Ninh hydropower lake is discharged along the Dong Nai river, not to Luy river.

On November 17, Lam Dong Provincial People's Committee directed agencies, units and localities in the area to improve natural disaster prevention and control, ensuring traffic safety. The Chairman of the Provincial People's Committee directed the Department of Construction, based on its assigned functions and tasks, to proactively implement or advise and propose to the Chairman of the Provincial People's Committee to direct the implementation of work to prevent, combat and respond to incidents caused by storms and floods to the traffic system and works in the province, especially on key traffic routes, with inter-regional connectivity to ensure smooth and safe traffic.

The People's Committees of communes, wards and special zones continue to coordinate and support road management agencies in arranging areas for dumping of collapsed soil and rocks to facilitate the repair of slope collapse incidents; support site clearance in cases where major damage requires widening the road towards the positive slope or rerouting to ensure safety. At the same time, support maritime and waterway management agencies in arranging dumping areas when dredging channels and creeks due to sedimentation that does not ensure the depth for ships to run, especially in river mouth areas during the rainy and flood season...
