In order to understand water quality situation in the lower Yellow River since the integrated dispatching of water quantity of the Yellow River, the current water quality situation there was analyzed according to the water quality monitoring data in 2006, and the water quality change tendency of five sections during 1999~2006 was statistics analyzed by using Daniel tendency inspection method. The results indicated that current water quality is good in the lower Yellow River, the water quality in flood season is better than that in non-flood season, the water quality of the lower reaches has gradually turned better since 1999, which is closely related to the effort of the water resources protection management department and the increase of water volume because of the integrated dispatching of water quantity of the Yellow River.
