The Central Yunnan Water Diversion Project (Chinese: 滇中引水工程; pinyin: Diānzhōng yǐnshuǐ gōngchéng) is a large-scale civil engineering project under construction that will allow water from the Jinsha River near Lijiang to be transported to Central Yunnan.

The region has suffered from long drought spells, such as a period of 30 months without heavy rains in Kunming.

[3] Construction was preceded by 16 years of preliminary work involving studying of the water use of the target area and selecting suitable routes.

[6] The project includes 58 tunnels with a total length of 612 km (380 mi), 25 inverted siphons, 17 aqueducts, and 15 culverts.

[3] Once completed, the project would improve water availability for 11 million people, spread over 35 counties in Yunnan and a total area of 36,900 km2 (14,200 sq mi).
