Flooding Update: Chao Phraya Overflows in Bangkok, Dam Breaks in Ayutthaya, Ang Thong

When the Chao Phraya River overflowed into Soi Samsen 23 in Bangkok’s Dusit District Sunday night, it marked the start of what could days of flooding.

District chief Thanin Niamhom said the the river rose due to a combination of an increase in headwaters, aggravated by greater inflows of seawater.

Much of the flooding has been drained today and the water did not flow into other areas and damage more homes, Thanin said.

Bangkok is under a flood warning from the rising Chao Phraya through Oct. 5 as the Thai Meteorological Department predicts more heavy rain covering the North, East and Central regions.

In response, city hall has begun reinforcing its flood defenses in nine riverside districts.

Bangkok Gov. Aswin Kwanmuang ordered the reinforcement of 80 kilometers of floodwalls running from Rama VII Bridge to Bang Na.

Sandbags also are being piled higher Dusit, Phra Nakhon, Yannawa, Bang Kholaem, Sathon, Bang Phlat, Thon Buri, Klong San and Rat Burana.

The National Water Command Center said rain accumulating in the upper Chao Phraya and the Pa Sak tributary could increase water levels through Oct. 5, putting those outside floodwalls in danger.

Evening flooding in Nonthaburi

In Nonthaburi, officials are fortifying flood barriers with extra sandbags. Areas along the Chao Phraya are at a higher risk of flooding. Water from upstream provinces is flowing through this river and into the sea.

Villages near Saeng Siritham Temple in Pak Kret District remain optimistic because the water level is still below the embankment during the day. However, minor overflows can be expected in the evening or during high tide.

The small evening overflow has become a common occurrence at villages behind Pranangklao Hospital. Residents have already moved their belongings to higher floors, and continuously monitoring water levels.

Ayutthaya dam breaks

In Ayutthaya, water is rushing through so fast that a two-meter dam behind Wat Chulamanee in Bang Ban District broke at early Sunday, submerging the temple’s neighborhood.

Water discharges from the Chao Phraya Dam also flooded 18,812 households in eight districts.

In Ang Thong Monday, a concrete embankment collapsed, causing the Chao Phraya River to overflow into a community in Chaiyo District. Some 200 houses have been submerged.

Finally, a flood warning was issued Monday for areas along the Chee River from Oct. 4-15 due to water discharges from the Maha Sarakham Dam. The affected six provinces are Khon Kaen, Maha Sarakham, Kalasin, Roi Et, Yasothon and Sisaket.
