The Upper Mun Reservoir was at 44 million cubic metres or 31.88 per cent of capacity, while 23 medium-sized reservoirs held a combined 101 million cubic metres of water or about 30 per cent of their total capacity, he added. Of them, 35 villages in Sung Noen, Chalerm Phrakiat and Phra Thongkham districts were declared drought disaster zones so far and were entitled to compensation. The Thai Meteorological Department meanwhile announced that the rainy season had begun on May 20 and would end around mid-October. The department predicted the period between June and mid-July would see only a small amount of rainfall over Thailand, resulting in insufficient water for farming. The department said heavy rains would come during August and September, posing the risk of floods.
