The Zhuoshui River (Chinese: 濁水溪) is a major river in west-central Taiwan. Starting in the Central Mountain Range in Nantou County, the river flows west toward the Changhua Plain, where it forms the border between Yunlin County and Changhua County, and empties into the Taiwan Strait. With a total length of 186.6 kilometres (115.9 mi),[4] it is the longest river in Taiwan.[5] It is known for its frequent flooding and has the highest sediment load of Taiwan's rivers, which earned it the name "Zhuoshui", muddy water.[6] The river serves as an unofficial boundary between the north and south of Taiwan.[7][8][9]
The Zhuoshui River basin has been inhabited by various indigenous peoples for at least 4,000 years. Although many indigenous groups were assimilated or driven out by Han Chinese settlement starting in the 1600s, the Atayal, Seediq, Bunun and Thao retain some of their traditional lands in the Nantou part of the basin. Han immigrants built Taiwan's first irrigation scheme on the Zhuoshui River, enabling the economic growth of the region. During Japanese occupation in the early 1900s, the upper Zhuoshui River was exploited for its natural resources, and resistance from indigenous groups led to numerous military confrontations including the Musha Incident.
The river has considerable economic importance. It is the site of one of Taiwan's largest hydropower schemes, an interconnected system of reservoirs, tunnels and power plants which include the Sun Moon Lake reservoir, one of Taiwan's most popular tourist attractions. The river is a key source of water for irrigation and industry in central Taiwan. In recent decades, sand and gravel mining and the construction of the Jiji Weir have significantly degraded the channel of the river.
