Rama VI Dam All six spillway gates of Rama VI Dam have been fully opened to increase water discharge from October 1 to 3, resulting in the Pa Sak River downstream rising approximately 1 to 1.5 meters. Residents in risk areas are moving their belongings to higher ground.
On 1 October 2026, reporters covering the water situation in Phra Nakhon Si Ayutthaya Province reported the need for close monitoring, especially along the Pa Sak River and low-lying areas outside flood embankments. The Department of Disaster Prevention and Mitigation (DDPM) warned that Rama VI Dam will increase water discharge to about 700-800 cubic meters per second from 1 to 3 October 2026, potentially raising Pa Sak River levels downstream of the dam by 1 to 1.5 meters.
Special monitoring areas include Tha Ruea, Nakhon Luang, Phra Nakhon Si Ayutthaya, and Bang Pa Han districts. Residents living along the riverbanks and in low-lying areas outside embankments are urged to move belongings to higher ground, relocate vehicles to safe zones, and closely care for vulnerable groups.
Currently, Rama VI Dam has opened all six spillway gates to speed up water release to accommodate inflows from upstream. Water levels just in front of the dam have slightly decreased, but downstream conditions require ongoing monitoring because Rapeepat and Nakhon Luang canals are at full capacity—around 100%—limiting their ability to handle additional water.
Mr. Methas Piriyasatit, Deputy Mayor of Tha Ruea Subdistrict Municipality, revealed that today water levels have dropped about one meter after accelerated water release, but the situation remains concerning. Rama VI Dam must handle inflows from Pasak Jolasid Dam and the Chainat-Pasak Canal. He noted that on 3 October, Pasak Dam is expected to release about 800 cubic meters per second.
This water will flow downstream of Rama VI Dam and may affect riverside homes, particularly in Tha Ruea and Nakhon Luang districts. Residents are advised not to be complacent, to prepare by moving belongings to higher ground, and to follow official announcements continuously. The municipality is actively informing villagers.
In Tha Ruea District, about 2,234 riverside households have already been affected by flooding. Residents in riverbank communities are closely monitoring water levels, as signs indicate rises from 1 to 3 October.
Mrs. Ratri Noppakun, a resident of Wat Satu Community in Tha Ruea District, said her home is on the Pa Sak Riverbank, and the community is among the first to be affected by annual floodwaters. When water levels rise, her family must relocate to relatives’ houses in Champa Subdistrict.
She continues to monitor the water situation daily but admits feeling stressed and worried, fearing rising waters may impact the area where her family has relocated. Despite only 3-4 days of continuous rain recently, water has already flooded homes and damaged belongings.
Mrs. Ratri said she hopes relevant authorities will closely track the situation and continuously warn residents to allow time for preparation and moving belongings if water levels rise as forecasted.
Meanwhile, riverside residents are vigilantly watching water levels and preparing, especially for vulnerable groups such as the elderly, bedridden patients, and young children who need special care and safe spaces arranged in advance.
Residents in risk areas are urged to closely follow announcements from Phra Nakhon Si Ayutthaya Province, district offices, irrigation, and disaster prevention agencies, as water levels may fluctuate according to discharge volumes and upstream inflows.
