The study included determining the current monthly changes taking place in the most important Physico-chemical specifications of the downstream public water at the point of intersection of a suit by Baghdad with the estuary town of Mahmudiyah, north-General to the point of intersection of Al-ssaouira protoplasm with River estuary year for the duration of the month of November 2009 to October 2010.
Water temperature ranged downstream the year between 11.1-28.9 °C, the amount of dissolved oxygen water between 7.2-8.6 mg/l, pH between 7–8.6, salinity ranged from 2.9–4.6 ppt. and the transparency ranged from 27.2–42.6 cm These results revealed the existence of significant differences in the measurements of these Physico-chemical characteristics of water downstream year, and the overall changes in the Physico-chemical specifications of the downstream public water is within the normal range borne by Common Carp
