    ABSTRACT: A study was conducted to characterize Modjo tannery effluent (wastewater) and determine its impact on the Modjo River using some physicochemical parameters. Accordingly, three tannery wastewater samples along wastewater channel at different distances have been taken and three river water samples (one upstream and two downstream) were collected along the river to determine its impact on the river. The samples have been analyzed for temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), total suspended solid (TSS), chloride(Cl﹣), biological oxygen demand (BOD5), chemical oxygen demand (COD), total ammonia (as N), total nitrogen, total phosphorus and sulphide. The result of tannery wastewater showed that the values of temperature, pH, EC, TDS, TSS, Cl﹣, BOD5, COD, total ammonia, total nitrogen, total phosphorus and sulphide along the wastewater channel ranged from 26.97℃ to 24.93℃, 9.33 to 8.33, 15,670.00 to 14,496.67 mg·L﹣1, 9370.00 to 8723.33 mg·L﹣1, 4979.33 to 2647.67 mg·L﹣1, 6111.67 to 5555.78 mg·L﹣1 , 960.34 to 842.00 mg·L﹣1, 2011.00 to 1950.75 mg·L﹣1, 520.44 to 401.23 mg·L﹣1, 720.46 to 665.43 mg·L﹣1, 30.12 to 19.55 mg·L﹣1, 35.56 to 21.05 mg·L﹣1 respectively. And most of the effluent characteristics except pH and temperature were beyond the provisional discharge limit of tannery effluent to water body set by the Ethiopian Environmental Protection Authority (EEPA) and Federal Environmental Protection Agency (FEPA). Analysis of variance (ANOVA) also showed that variation among sampling points was statistically significant (p
