Water delivery has been run over 30 years. the main canal has the problem that the actual conveying capacity is very low now and the conveying capacity of the east - one main canal i only half of the design value, this lead to guaranteed real - time efficiency of the irrigation of the farmland recede greatly. the downstream has no water and crops were drought to death have been seen more times in the irrigation period, this lead to the contradictory between the upstream and downstream on water usage, moreover, the lower discharge capacity of the dry canal in irrigation period is the main cause of the actual irrigated area is only half of the design value
經過三十年的輸水運行，目前乾渠工程存在嚴重的輸水能力低問題，其中東一乾渠輸水能力只能達到原設計的1 2 ，使農田的適時灌溉保證率大大降低，多次發生灌溉期下游見不到水而旱死莊稼的情況，造成上下游用水矛盾突出，而且灌溉期乾渠過流能力偏小，是導致實際灌溉面積僅為設計值的1 3的重要原因。
