Ayutthaya: The Royal Irrigation Department has reaffirmed its commitment to controlling the Chao Phraya Dam’s water discharge rate at 2,700 cubic meters per second. This decision comes as the department closely monitors potential rainfall resulting from Tropical Storm Kalmaegi, which could lead to increased water flow into the Chao Phraya Basin.

According to Thai News Agency, Thanet Somboon, Director of the Office of Water Management and Hydrology, reported that the discharge rate of 2,700 cubic meters per second is the highest since recent heavy rainfall. This rate has affected the Ping, Wang, Yom, and Nan river basins located downstream of the dam. While the dam still retains capacity to hold water, downstream rainfall accelerates the flow into the Chao Phraya Basin.

Mr. Thanet also mentioned the development of a water management plan in anticipation of Tropical Storm Kalmaegi. The Meteorological Department has forecasted extensive rainfall across Thailand, prompting measures to optimize water distribution through the irrigation system on both sides of the dam. Should the water level exceed control limits, there is a risk of overflow affecting riverside areas in provinces north of the dam.

The Office of National Water Resources (ONWR) has been informed to prepare for a potential increase in the discharge limit beyond 2,700 cubic meters per second if necessary. Nonetheless, efforts will focus on maintaining the current discharge rate to minimize further impact on the lower Chao Phraya Basin.
