The Department of Disaster Prevention and Mitigation (DDPM) counted flooding in 2 Saraburi districts, Nong Khae and Wihan Daeng, at 06:00 on 8 October 2026: 10 subdistricts, 23 villages and 518 households, with 1 death and the water falling [1]. That is far below the peak on 30 September, when DDPM counted all 13 districts, 87 subdistricts, 566 villages and 5,393 households [2].
The flooding began on 19 September, when a flash flood hit Muak Lek district and left water in low-lying homes for more than 2 hours [3]. Flash floods returned on the night of 24 September in Muak Lek, Lam Phaya Klang, Nong Yang Suea and Sap Sanun subdistricts [4].
Highway 1 between Pak Khao San and the Phu Khae Botanical Garden junction was the main road problem. Department of Highways lists showed 2 impassable points there on 4 October [5], and 1 point, at km 104+300-104+500, on 5 October.
The Pa Sak River is still running high. On 8 October three of five gauge stations in the province read between 81% and 84% of bank height, and none was over its bank. Pasak Jolasid Dam, upstream in Lopburi, held 106.80% of its storage on 30 September and opened all 7 gates [6].
DDPM has reported 1 death in Saraburi since 26 September without naming the person [7]. Separately, an 11-year-old boy died on 29 September in Nong Khae after being sucked into an uncovered drain full of floodwater [8].
The Office of the National Water Resources (ONWR) has asked people along the Pa Sak in Saraburi to watch for sudden rises during forecast rain on 9-12 October [9].
Krap AI is a free platform developed on a voluntary basis to support Thailand's AI future. It can be used for general conversations, and development is ongoing to enable flood forecasting by processing open-source data—a crucial capability for managing natural disasters like floods in Thailand.
You can chat with Krap AI to get the latest updates on Saraburi flood disasters. While Krap AI utilizes its own dedicated flood AI model, it can also employ other AI models as a fallback during periods of high traffic.
DDPM's daily counts show a sharp rise and a steady fall. The province went from 5 villages on 20 September to 566 villages on 30 September, then back to 23 villages by 7 October.
| Date, 06:00 Data | Districts | Subdistricts | Villages | Households |
|---|---|---|---|---|
| 20 September [10] | 2 | 3 | 5 | 57 (179 people) |
| 25 September [11] | 3 | 6 | 17 | 179 |
| 26 September [7] | 8 | 21 | 53 | 297 |
| 29 September [12] | 8 | 21 | 53 | 297 |
| 30 September [2] | 13 | 87 | 566 | 5,393 |
| 3 October [13] | 8 | 40 | 186 | 3,066 |
| 4 October [14] | 7 | 32 | 166 | 1,983 |
| 5 October [15] | 7 | 32 | 107 | 2,165 |
| 6 October [16] | 2 | 7 | 21 | 628 |
| 7 October [17] | 2 | 10 | 23 | 518 |
| 8 October [1] | 2 | 10 | 23 | 518 |
The 20 September row counts 179 people, while the 25 September row counts 179 households, so the match is a coincidence. Some days do not move smoothly: on 5 October villages fell while households rose, and on 7 October subdistricts rose while households fell, and DDPM gave no explanation. The count stayed at 5,393 households from 30 September to 2 October, and DDPM reported the water falling every day from 25 September.
Rain fell across 76 provinces and Bangkok from 17 September, and Saraburi flooded on 19 September [10]. In Muak Lek subdistrict a flash flood put water in low-lying homes along a waterway for more than 2 hours [3]. At Ban Tha Sao, Moo 13, 13 houses were damaged by mud and at risk of repeat flooding, and about 30 people moved into a temporary shelter at Wat Tha Sao [3].
On 20 September the governor, the provincial Red Cross chapter head and the district chief joined DDPM, the military, police, civil defence volunteers and 904 royal volunteers to clean homes and survey damage [18]. Water at Muak Lek Waterfall returned to normal but stayed slightly turbid, and swimming was barred while sightseeing stayed open [18].
The Deputy Prime Minister, acting on the Prime Minister's instruction, ordered the governor and DDPM that day to set up a forward command post, run pumps with the Royal Irrigation Department, care for vulnerable groups and survey damage [10]. The Thai Meteorological Department (TMD) forecast heavy rain on 24 September and very heavy rain on 25 and 26 September [19].
The second flood followed from the evening of 24 September. A district warning went out at 22:48, and flash floods struck Muak Lek, Lam Phaya Klang, Nong Yang Suea and Sap Sanun subdistricts, with water receding by 03:20 on 25 September [4]. In Sao Hai district, continuous rain on 24 September caused standing water and overflow in Ton Tan and Phraya Thot subdistricts [20].
Few depth figures have been published. At Nong Kae in Phra Phutthabat district the water was steady at about 90 cm on 27 September [21]. The drain in which the boy died in Nong Khae held about 80 cm of water [8].
On the Pa Sak at Saraburi town the level was 8.51 m on 25 September, from a municipal notice that names no gauge station [22]. No page gives the depth on any road or in any shelter.
The Department of Highways reported 4 impassable points in Saraburi on 28 September: Highway 1 between Pak Khao San and the Phu Khae Botanical Garden junction at km 103+000-104+200 and km 104+000-104+500, Highway 1 on the Hin Kong-Pak Khao San stretch, and the Highway 362 ring road at km 31+000-31+345. Two reports that day disagree on the Hin Kong-Pak Khao San stretch, one giving km 95+000-103+000 and the other km 95+000-95+400.
| Date | Impassable Points in Saraburi |
|---|---|
| 29 September [23] | 2: Highway 1 km 103+000-105+400 and km 104+000-104+500 |
| 30 September [24] | 2: same two stretches |
| 2 October [25] | 2: same two stretches |
| 4 October [5] | 2, no detail given |
| 5 October | 1: Highway 1 km 104+300-104+500 |
The Highway 1 stretch between Pak Khao San and Phu Khae therefore had at least one impassable point in every report from 28 September to 5 October. The lists for 11:00 on 6 October and 18:00 on 7 October did not name Saraburi among the impassable points, but they list only impassable points, so they don't show that no highway was flooded. No page confirms that Highway 1 has fully reopened.
On 27 September flash flooding receded at the Nong Muang junction at Huai Bong in Chaloem Phra Kiat district, and Phahonyothin Road at the Huai Bong junction was passable, though water remained in the left Bangkok-bound lane [26]. No depth or condition report exists for rural roads in the province.
All 13 districts were counted on 30 September [2]. After 5 October DDPM lists only Nong Khae and Wihan Daeng, but no page says the water has fully receded elsewhere.
Muak Lek took both flash floods and sits at the centre of the early response. On 25 September the DDPM sent a Cell Broadcast at 14:25 ordering residents of Moo 12 and 13, Ban Tha Sao, to evacuate immediately to the shelter at Ban Khao Mai Kwian school. The Muak Lek subdistrict administrative organisation (SAO) cleaned the Moo 11 community hall and the drains at a school on 26 September [27].
For 26-30 September ONWR listed Kaeng Khoi and Muak Lek as risk areas and warned that the Pa Sak River in Saraburi could overtop its banks [28].
On 27 September the Nong Nak drainage canal overflowed in Nong Khae, flooding the Nong Khae Kao, Ko Loi Phatthana, Nong Kang and Charoen Sap communities, the morning market, shops, a school and a temple [29]. The same day, the governor visited Charoen Tham and Nong Mu subdistricts in Wihan Daeng, including the temporary shelter at Charoen Tham SAO and the Wat Khlong Mai sluice gate [30].
On 6 October the deputy governor checked drainage at three points in Kum Hak and Nong Chorakhe subdistricts and ordered faster drainage from Khlong 26 Left into Khlong Raphiphat, a damage survey and a watch for heavy rain on 4-8 October.
Heavy rain on 26 September flooded homes in Don Thong, Nong Don, Ban Prong and Ban Klap subdistricts of Nong Don district [21]. On 27 September the deputy governor found the Nong Don pumping station running one pump at about 2 cubic metres per second, with the provincial administration supplying 2 boats and 1 pump [21].
Standby evacuation centres at Wat Nong Kae, Moo 1, and Wat Pradu, Moo 5, were readied for about 200 people each, and a 20-inch pump was installed at Bang Khamot in Ban Mo [21].
In Sao Hai the mayor of Ton Tan-Phraya Thot visited the flooded area at 06:00 on 25 September, and the provincial administration lent a machinery team to open waterways [20]. A warning for Ton Tan floating market and Moo 2-6 of Ton Tan followed on 30 September, but it was a warning of Pa Sak rises, not a flood report.
DDPM has reported 1 death in Saraburi since 26 September [7]. No page names the person, and the figure has stayed at 1 through 8 October [1].
Separately, on the morning of 29 September an 11-year-old boy was sucked into an uncovered drain on old Phahonyothin Road in Huai Sai, Nong Khae, where the water stood about 80 cm deep. His body was found about 200 m away after more than 4 hours of searching and sent to Nong Khae Hospital [8].
An 18-year-old man went missing while riding home on the Muak Lek-Wang Muang route on the night of 24 September, and his body was found the next morning after the water receded. The report does not say the flood caused his death, and nothing links it to the DDPM count. No injury figure has been published.
About 30 people stayed at Wat Tha Sao on 20 September [10], and a second shelter opened at Ban Khao Mai Kwian school [4]. The Nong Don SAO shelter held 9 people on 26 September, 6 already there and 3 new [21].
No province-wide shelter count has been published after 27 September.
Pasak Jolasid Dam is in Lopburi, upstream of Saraburi, and no page says it caused flooding in Saraburi. On 30 September all 7 gates were open, storage was 930.78 million cubic metres (106.80%), inflow was above 550 cubic metres per second and the release rose from 115.08 to 145 cubic metres per second, with downstream levels in Saraburi and Ayutthaya expected to rise 1.00-1.50 m [6].
A separate notice listed planned releases of 230 cubic metres per second on 1 October, 400 on 2 October and 500 on 3 October, with Ton Tan floating market and Moo 2-6 of Ton Tan as watch areas. Storage read 109.8% on 5 October and 104.2% on 8 October.
Gauge readings from the National Hydroinformatics Data Center at 12:30 on 8 October show none of five stations over its bank. The Pa Sak bridge at Ban Na Chong in Mueang Saraburi stood at 84% of bank height, the fire-raft station in Mueang Saraburi at 81%, and the canal bridge at Ban Sarang Sok in Ban Mo at 81%. Ban Pa in Kaeng Khoi was normal at 65%, and Wat Tha Rahat in Wang Muang was low at 24%.
On 27 September four gates of the Khlong Huai Rae weir in Phueng Ruang were raised to drain into the Pa Sak, and bags were handed to 37 vulnerable households in Chaloem Phra Kiat [26]. On 1 October the deputy governor inspected 12-inch and 16-inch pumps at Pak Khlong 33 and a 30-inch pump at Moo 4, Khlong Hok Wa Sai Bon, all draining into Khlong Raphiphat [31].
The Gulf group handed over 6,750 relief bags at the Kaeng Khoi district hall on 5 October, 3,350 of them for Saraburi and 3,400 for Ayutthaya, to be passed to affected people in every district [32]. The company also said it had prepared 15,000 more bags for 16 provinces including Saraburi, with no Saraburi share given and no word on overlap [33].
PTT Group said it delivered 3,510 relief bags to Bangkok and 8 provinces including Saraburi, with no per-province split. On 29 September the Protected Area Regional Office 1 cleaned Ban Tha Sao and handed out 200 sets of food and drinking water in Sarang Sok [34].
The national compensation scheme pays 9,000 baht per household for homes flooded 7 days or more and 5,000 baht for homes surrounded by water, through the Tang Rath app, for events before 1 October [35]. No Saraburi claim or payment count has been published.
In Nong Don, about 2,526 rai of farmland and 199 farmers in 4 subdistricts and 14 villages were expected to be damaged, according to a 27 September inspection, and no crop is named [21]. No livestock or fisheries figure exists. Muak Lek Waterfall stayed open for sightseeing after the first flood [18].
ONWR called on 7 October for a watch on sudden rises, bank overflow and ponding along the Pa Sak in Phetchabun and Saraburi, with more rain forecast for the central region on 9-12 October [9]. TMD's heavy rain announcement for 9-13 October lists Saraburi among central provinces expected to be affected on 10 October. On 5 October the Deputy Prime Minister ordered a watch for a new round of rain on 10-12 October, with warnings down to district and subdistrict level [35].
A flash flood hit Muak Lek district on 19 September 2026 [3].
DDPM counted 518 households in Nong Khae and Wihan Daeng districts at 06:00 on 8 October 2026 [1].
DDPM reports 1 death, unnamed [1]. A boy also died in a flooded drain in Nong Khae on 29 September [8].
Highway 1 near Pak Khao San and the Phu Khae Botanical Garden junction was impassable at 1 point on 5 October, and no page confirms it has fully reopened [5].
No gauge station was over its bank at 12:30 on 8 October, though three read between 81% and 84% of bank height.
No. Krap collects public flood reports and doesn't issue official warnings or dispatch rescue.
