As of 23 August 2026, the four main dams (Bhumibol, Sirikit, Kheo Noi and Pasak Chonlasit) held about 60% of capacity and could take roughly 9,999 million cubic metres more. The Nakhon Sawan gauge sits 6.62 m below the bank, and no flooding has been reported in the eight central provinces, including Bangkok. Tropical storm Nara is forecast to hit southern China, not Thailand directly. For now no action is needed, but if you run a business in low-lying or flood-prone areas along the river, keep checking official water and rain updates through the rainy season.
