According to preliminary statistics, in 1984, the total water supply for all water conservancy projects was 429 billion cubic meters (excluding water for hydropower), including 354.2 billion cubic meters of agricultural irrigation water and 74.8 billion cubic meters of industrial and urban domestic water. 1984 irrigation area of 599000000 acres, the average irrigation of 591 cubic meters per mu. By project facilities: 140.7 billion cubic meters of water supply for water storage projects, 17.6 billion cubic meters of water supply for diversion works, 44.2 billion cubic meters of water for electromechanical wells and 57.4 billion cubic meters of water for electromechanical pumping stations.
