Thailand will see more rains today (July 22), but these will decrease tomorrow and the day after before increasing again around the weekend, Office for National Water Resources deputy secretary-general Samrerng Saengphuwong said.

“This will help increase the level of water in rivers, canals, reservoirs and dams, especially in the upper and lower Chao Phraya basin in the Central region,” he said.
“To make the fullest use of the situation, the office has asked the Royal Irrigation Department and the Electricity Generating Authority of Thailand [Egat] to reduce the drainage rate of Bhumibol Dam in Tak province from today until July 28 from 5 million cubic metres to 4 million cubic metres per day to conserve water in the dam, while the rain will help fill reservoirs in the areas below the dam,” Samrerng said.
Bhumibol Dam currently holds 3.91 billion cubic metres of water, or 29 per cent of its capacity.
“Since July 15, rains have helped fill the dam by up to 10 million cubic metres and we estimated that around 4 million cubic metres will be added from July 22 to 24,” he said.
Meanwhile, Sirikit Dam in Uttaradit province holds 3.26 billion cubic metres of water, or 34 per cent of its capacity. It is estimated that from today to Thursday, rains will add around 37 million cubic metres of water to the dam.
“The office has instructed Egat to reduce the dam’s draining rate from July 22 to 26, from 14 million cubic metres to 12 million cubic metres a day to increase the amount of its water,” Samrerng said.
The flood in Phetchabun’s Lomsak district due to heavy rains on July 15 and 16 has now subsided as the water mass has flowed to Pasak Dam in Lopburi province, he added.
