For example, when the design flow of upward of the peace bridge of upward of the east - one main canal is 45m3 / s, the actual flow quantity is 23. 8m3 / s on the 30th of september in 1989, the water level of the transition region terminal of the mouth of hao wan flume of the east - one main canal had gained the design level of 4. 3m, and the level between downstream and shang tian yuan tunnel was generally higher. it says that the actual discharge capacity now is only about 24m3 / s which is half of the design value. this not only make the benefit of the irrigation district abnormal, but also greatly hinder the economic development of the irrigation district, and lead to the canal run frequently at small flow, high water level, lengthen the discharge duration
如東一乾渠上段太平橋以上設計流量45m ~ 3 s ， 1989年9月30日實測通水流量23 . 8m ~ 3 s時，東一乾渠郝灣渡槽出口漸變段末端水位已達到設計水位4 . 3m ，其下游至上天院隧洞水位也普遍偏高，即東一乾渠上段目前僅能通過流量24m ~ 3 s左右，只有設計值的50左右，不僅使灌區效益得不到正常發揮，嚴重阻礙了灌區范圍內的經濟發展，而且使渠道經常處于小流量、高水位運行，延長了次通水時間，大大增加了渠道工程的安全管理難度。
