Roughly meaning "Mother of Rivers" in Thai and Lao languages, the Mekong River is a sacred lifeline in Southeast Asia.

The upper half of the Mekong originates in the Tibetan Highlands in southwest China where it is known as the Lancang. It flows southeast through Yunnan province, pictured here, before crossing into Southeast Asia. FREDERIC J. BROWN/AFP/AFP/Getty Images
The brown waters of the Mekong meet the tripoint of China (left) Myanmar (right) and Laos. From there it flows along the border of Myanmar and Laos, and then roughly traces the border of Thailand and Laos before crossing Cambodia and Vietnam and emptying into the South China Sea.

Millions of people up and down the Mekong depend on the river for its resources and also for their livelihoods. Here, a fisherman casts his net into the river in Phnom Penh, Cambodia. TANG CHHIN SOTHY/AFP/GettyImages

Communities living on the river are vulnerable to flooding, particularly during the monsoon season. In 2013, floods in Cambodia left more than 80 dead and wreaked havoc in villages like this one in Kandal province.

The Mekong is not just one river. Thousands of rivers and streams feed into the main river, including the Nam Khan tributary in Laos, pictured here. During the dry season, villagers build a bamboo bridge to cross the river. Khomkrish Innanchai/MekongRiverCommission
It is also a sacred place for local communities. Each April, a water splashing festival takes place on the banks of the Lancang-Mekong River to celebrate the new year for the Dai ethnic minority of Xishuangbanna in southwest China. Similar water festivals take place across Southeast Asia to bring in the new year. Guang Niu/Getty Images
Another water festival takes place in Cambodian capital Phnom Penh each November to commemorate the end of monsoon season. This long dragon boat carrying 179 rowers and measuring 87.3 meters will be on display during this year's water festival.
