The Office of National Water Resources (ONWR) has said it will finish drafting the country's first-ever water map to help manage river basins in the north by the end of this year.
The state agency hopes the water map will be a key tool for both land and water resources management as part of flood-control efforts, said Chayan Maungsong, ONWR's deputy secretary-general.
Once completed, it will oversee water projects for the Ping, Wang, Yom and Nan. These four rivers are a source of the Chao Phraya River, the country's largest basin, he said.
