Irtysh–Karamay–Ürümqi Canal

The Irtysh–Karamay–Ürümqi Canal, also known as the Project 635 Canal, is a system of water-transfer canals and reservoirs in the northern part of China's Xinjiang Uighur Autonomous Region. It transfers water from the Irtysh River into several dry endorheic basins of north-central Xinjiang, where it is used for irrigation and general use of the population and industries.

The canal is often referred in Chinese publications simply the "Project for Supplying Water From the Irtysh".According to Chinese planners, the water carried by the canal will eventually irrigate 140,000 hectares of land. An important user of the canal's water is the petroleum industry around Karamay.
