The Royal Irrigation Department on Sunday reduced the amount of water being discharged from the Chao Phraya dam in Chai Nat for the sixth consecutive day as the flood situation in the Chao Phraya River basin improved further.
RID officials said the department had reduced the amount of water being discharged from the Chao Phraya barrage to 1,473 cubic metres per second, from 1,705 cu/m per second, which will further ease flooding in low-lying areas of Chai Nat, Sing Buri, Ang Thong and Ayutthaya. The discharged water was below 1,500 cu/m per second for the first time in a month.
The level of floodwater in the four provinces continued to decrease by between 30 and 50 centimetres since Saturday. At 1pm on Sunday, less water was passing through the dam, now flowing at 1,821 cu/m per second, down from 1,922 cu/m per second.
The flood situation in the Chao Phraya River basin has improved as water levels in all nine flooded provinces have receded, the Disaster Prevention and Mitigation Department announced early this week. The situation is expected to return to normal by the end of the month, according to RID deputy chief Thongplew Kongjun.
Five other flooded provinces are Nakhon Sawan, Pathum Thani, Suphan Buri, Saraburi and Phichit.
