All large- and medium-sized dams in the country are discharging water as planned in preparing to take more rainwater expected to be brought about by tropical storm “Bebinca”, Office of National Water Resources (ONWR) director-general Somkiat Prajamwong said on Wednesday.

He said special attention is now on Kaeng Krachan dam in Phetchaburi, Srinagarind and Vajiralongkorn dams in Kanchanaburi, Ratchaprapa dam in Surat Thani and Khun Dan Prakan Chon dam in Nakhon Nayok.

Khun Dan Prakan Chon dam will be under close watch this week after 100 milimetres of rain poured on mountains on Aug 13, sending run-off that caused sudden flooding at two waterfalls in Nakhon Nayok.

The dam, with a capacity of holding 225 million cubic metres of water, is now holding 188 million cu/m of water or 83% of its capacity, he said.

Today’s inflow was 12 million cu/m while the dam is discharging water at 3 million cu/m per day. As more rain is likely to come in the next few days, the water discharge rate may have to be adjusted, he said.

Vajiralongkorn dam is discharging water at the rate of 42 million cu/m per day.
