The limnological study of Maroon River was initiated along Idanak station and the district was continued to the Cham-e-nezami. Sampling was started from the spring of 2014 and continued to the winter of 2015 from four specific stations. Seasonal sampling was performed from any station to determine water factors, planktons, macrobenthos and fishes. They were transferred to lab to be analyzed. At the same time, some physical and chemical factors in terms of DO, pH and temperature, salinity and conductivity were recorded. The result indicated that the amount of TDS and TSS, turbidity was increasing from station1 to station 4. Also, 6 phytoplankton jenus, 2 zooplankton jenus, 7 macrobenthos and 5 fish were recognized. The results of diversity indices indicated that the highest diversity macrobenthos species was in spring in station 1 and 2 and the lowest was in summer in station 3. On the basis of HFBI index, four grades of suitable, relatively poor and poor water qualities were distinguished at all the sampling stations.
