Water samples were collected monthly from December 2012 to November 2013 at five stations along the river . The TRIX index integrates dissolved inorganic nitrogen and phosphorus, oxygen saturation percentage and chlorophyll–a .The TRIX index is scaled from 0 to 10 , the values in this area ranged from 5.74 to 7.12 . The results demonstrate the status of Shatt ranged from moderate quality to poor and degraded quality , eutrophication level ranged from high to elevated ( very high)
