Chai Nat battered as Chao Phraya embankment collapses; over 400 homes flooded
Chai Nat faces severe flooding after a temporary Chao Phraya embankment collapsed in two sections, inundating over 400 homes as dam discharge remains high
The flood situation in the Chao Phraya River Basin remains critical, with continuing high discharge from the Chao Phraya Dam in Chai Nat Province at 2,900 cubic metres per second for the fourth consecutive day. The increased flow has severely affected downstream areas in Sapphaya district, where a temporary 4-kilometre embankment made of crushed rock has collapsed in two locations, sending floodwaters rushing into more than 400 households.
On November 14, 2025, the Chao Phraya Basin continued to face severe flooding. Water flow at Station C2 in Nakhon Sawan was recorded at 2,976 cubic metres per second. Upstream water level at the Chao Phraya Dam was 17.50 metres (MSL), while downstream water level was 16.67 metres (MSL), 33 centimetres above the riverbank. Dam discharge was maintained at 2,900 cubic metres per second for the fourth day.
The high discharge has impacted communities downstream of the dam, particularly Bang Luang Subdistrict in Sapphaya. The temporary crushed-rock embankment stretching over 4 kilometres breached at two points, allowing floodwaters to quickly inundate Moo 1 and Moo 2. Approximately 400 households have been affected, with water levels ranging from 50 centimetres to as high as 2 metres depending on the area.
Sirin Phatsorn, a resident of Moo 2 in Bang Luang, Sapphaya, Chai Nat, said the breached areas were part of a temporary embankment made of crushed rock, which was rapidly eroded by the strong currents of the Chao Phraya River.
“We’re in real hardship now. We must wade to our homes because cars cannot pass. The water began rising as soon as the dam increased discharge to 2,900 cubic metres per second. The municipality had already warned us to move belongings to higher ground, knowing the embankment might not hold,” he said.
