The Irtysh-Karamay-Urumqi 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 (which flows toward the Arctic Ocean) into several dry endorheic basins of north-central Xinjiang, where it is used for irrigation and general use of the population and industries.
