Water supplies in four main dams are adequate for consumption and agriculture during the dry season, according to the Royal Irrigation Department (RID).
Deputy director-general Thongplew Kongchan said the total volume of water in the dams was 20.8 billion cubic metres (cu/m), or 84% of their capacity, with 14.1 billion cu/m of usable water, or 78% of capacity.
The four are the Bhumibol dam in Tak, the Sirikit dam in Uttaradit, the Khwae Noi Bamrungdan dam in Phitsanulok and the Pasak Jolasid dam in Lop Buri.
The RID is working on a water allocation plan so water supplies will be sufficient throughout the dry season, which officially began on Nov 1.
Mr Thongplew asked for cooperation from the public and private sector to use water sparingly for the sake of future water needs.
Speaking about the water situation along the Chao Phraya River in the Central Plains areas, the RID deputy chief said the water level in the river had receded by 10 centimetres since Sunday.
The water volume discharged to downstream areas of the Chao Phraya barrage also has dropped to 2,147 cu/m per second, resulting in low water levels in Klong Phong Pheng, Klong Bang Ban and the Noi River in Ayutthaya.
As the situation continues to improve, in Nakhon Sawan, the water volume flowing into the C2 water station in Muang district on Monday also decreased to 2,515 cu/m per second, he said.
As for the discharge of water from low-lying farmland, Mr Thongplew said water had been drained from all paddy fields, starting with Bang Ra Kham field in Phitsanulok which currently holds a total water volume of 431 million cu/m after 69 million cu/m was released from the field.
For the remaining 12 fields in the lower Central Plains areas, they currently hold 1.3 billion cu/m of water after 40.5 million cu/m was drawn from the areas.
The RID expected to drain all the water from the fields by next month, Mr Thongplew said.
Meanwhile, in Chai Nat's Sapphaya district, Wat Maprang School remained inundated by floodwater, which has forced more than 30 Prathom 6 (Grade 6) students to temporarily use a nearby building for classes since last Wednesday.
School director Oranong Phuyathorn said the water level in the school reached 30cm yesterday.
The Provincial Disaster Prevention and Mitigation Centre Region 16 yesterday installed two water pumps in Wat Wat Maprang and Wat Wang Sakhon in tambon Pho Dam Nang Ok to help manage the situation.
The two flood-ravaged zones are currently inundated with stagnant water covering around 100 rai left behind by run-off from local waterways.
