Ta Trach Lake is capable of cutting the flood peak of 500mm rain.

On October 22, the City Civil Defense Command said that irrigation reservoirs in the area have reached 73% of their design capacity (about 82 million m3/113 million m3). Irrigation and hydroelectric reservoirs now have plans to proactively operate the works and downstream areas safely according to heavy rain scenarios.

Since September 28, the City Civil Defense Command has issued five orders to operate reservoirs in the Huong River basin to gradually lower the water level of the reservoirs to create flood prevention capacity, preparing for heavy rains caused by storm No. 12. Currently, most of the water levels in the reservoirs are maintaining lower levels than normal water levels.

The current water level of Huong Dien and Binh Dien reservoirs is capable of cutting the flood peak of a 400mm rainstorm, and Ta Trach reservoir is capable of cutting the flood peak of a 500mm rainstorm. The specialized agency has developed 4 inter-reservoir operation scenarios corresponding to rainfall of 600-1,000mm.

High tides cause water to rise and flood residential areas in Thuan An.

Due to the influence of storm circulation and cold air combined with East wind disturbances and topographic effects, it is forecasted that from October 22-24, there will be heavy rain and very heavy rain on land. The total rainfall for the entire period due to the influence of storm No. 12 is generally 250-500mm, in some places over 600mm. Rain combined with the influence of big waves and high tides has caused water from the sea to overflow into Tam Giang lagoon, causing local flooding in low-lying areas, areas of Thuan An, Duong No, Hoa Chau wards... and the area along the lagoon, Con Toc ferry (Dan Dien commune).
