The aim of the present work was to assess the downstream pollution influence of Sodo Town on water quality and macroinvertebrate community structure. Among four sampling sites, three sites were at downstream of the town whereas a reference site was at upstream. Physicochemical data with sample of macroinvertebrates was taken at upstream, midstream and downstream of the sampling sites from September to January 2016/17. Water quality test including temperature, electrical conductivity, TDS and salinity were measured in-situ and the recorded result in ranges 7.385 to 8.46 pH meters, 20.25 to 22.28 & Copyright@ International Science Community Association
